Related dynamical process and modeling studies are also overviewed. The circulation and its variabilities consist of three predominant and interacting scales: basin scale, subbasin scale, and mesoscale. Highly resolved and unbiased maps of the basin wide circulation in the thermocline layer are presented which provide a new depiction of the main thermocline general circulation, composed of subbasin scale gyres interconnected by intense jets and meandering currents. Semipermanent features exist but important subbasin scale variabilities also occur on many time scales. Mesoscale variabilities modulate the subbasin scale and small mesoscale eddies populate the open sea, especially the south-eastern Levantine basin. Clear evidence indicates Levantine Intermediate Water (LIW) to be present over most of the Levantine Basin, implying that formation of LIW is not localized but rather is ubiquitous. The Ionian and Levantine basins are confirmed to form one deep thermohaline cell with deep water of Adriatic origin and to have a turnover time of one and a quarter centuries. Prognostic, inverse, box and data assimilative modeling results are presented based on both climatological and POEM data. The subbasin scale elements of the general circulation are stable and robust to the dynamical adjustment process. These findings bear importantly on a broad range of problems in ocean science and marine technology that depend upon knowledge of the general circulation and water mass structure, including biogeochemical fluxes, regional climate, coastal interactions, pollution and environmental management. Of global ocean scientific significance are the fundamental processes of water mass formations, transformations and dispersion which occur in the basin.</td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0012-8252</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td>JUL</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>1992</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>32</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>4</td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td>285</td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td>309</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:A1992JG26100002</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=8"></a>AU </td> <td>PASCHINI, E<br> ARTEGIANI, A<br> PINARDI, N</td> </tr> <tr> <td valign="top" style="width: 25px">TI </td> <td>THE MESOSCALE EDDY FIELD OF THE MIDDLE ADRIATIC SEA DURING FALL 1988</td> </tr> <tr> <td valign="top" style="width: 25px">SO </td> <td>DEEP-SEA RESEARCH PART I-OCEANOGRAPHIC RESEARCH PAPERS</td> </tr> <tr> <td valign="top" style="width: 25px">AB </td> <td>The analysis of the first mesoscale experiment in the middle Adriatic Sea reveals the horizontal and vertical scale of the eddy field.

Major well known features in the circulation are revealed in the data set which covers the period from October 1985 to April 1987. A prominent signal associated with the seasonal variability is identified in the water outflowing along the Italian coast. Differences between autumn and spring in the vein of cold and fresh water flowing along the Italian shelf manifest mainly in the temperature field. During the stratified season the fresh water spreads over the entire surface layer of the southern Adriatic. On the other hand, during spring, when the sea is vertically homogeneous, the fresh water remains confined to the surface longshore boundary layer over the entire length of the Italian coast. Layers below the seasonal thermocline at the eastern portion of the sea display very weak seasonal signals. A strong signal associated with the inter-annual variations also has been documented from the analysed data set; it mainly appears in the salinity field. It is shown that in spring 1986, the salinity averaged over the entire water column north of the Palagruza Sill is lower by 0.3 psu than in spring 1987. A similar, but less prominent difference is noted in the southern Adriatic. An attempt is made to associate these differences with variations in climatic conditions over the area, the river runoff and the Mediterranean water inflow.</td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0967-0645</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>1993</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>40</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>6</td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td>1143</td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td>1180</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:A1993MX35300003</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=10"></a>AU </td> <td>Vischetti, C<br> Businellil, M<br> Marini, M<br> Merlini, L</td> </tr> <tr> <td valign="top" style="width: 25px">TI </td> <td>Comparison of PRZM-2 computer model predictions with field data on the fate of napropamide and pendimethalin in soils</td> </tr> <tr> <td valign="top" style="width: 25px">SO </td> <td>EUROPEAN JOURNAL OF AGRONOMY</td> </tr> <tr> <td valign="top" style="width: 25px">AB </td> <td>The ability of Pesticide Root Zone Model (PRZM-2) to simulate the movement of napropamide and pendimethalin residues in the tobacco crop was evaluated using the soil properties and amounts of rainfall and irrigation in three field trials conducted in two unsaturated zone fields in the ploughed layer (0-40 cm).<br> The results of PRZM-2 simulation do not agree with observed field data, which also show a high variability.

Both nutrients and standing crop (the latter measured as chlorophyll a concentration and phytoplankton cell density) showed a concentration gradient from west to east with marked changes of average values from 6 to 15 NM off the coast. Nutrients and standing crop appeared to be positively correlated and both showed an inverse dependence on salinity which was mainly influenced by freshwater inputs from the major Italian river, the Po. Primary production rates showed values of about 260 and 210 g C m(-2) year(-1) at the 1.5 and 6 NM stations respectively indicating the presence of a narrow coastal belt with productivity levels significantly higher than those previously reported for other Adriatic areas affected by the Po. The offshore station at 15 NM gave an average annual production of about 120 g C m(-2) year(-1) which lies in the range reported for lagoons and coastal waters in the Po delta area. The photosynthetic efficiency was similar at the 1 5 and 6 NM stations (respectively 4.0 +/- 2.3 and 3.5 +/- 2.7) but significantly lower at the 15 NM station (1.9 +/- 1.7). This difference reflects either different nutrient levels in inshore and offshore stations or different structures in phytoplankton community: diatoms and phytoflagellates prevailed at 1.5 and 15 NM, respectively. Photosynthetic efficiency increased with increasing concentration of nutrients. The behaviour was found to be linear as a function of total dissolved phosphorus, and hyperbolic as a function of total dissolved nitrogen. This different dependence suggests a surplus of nitrogen with respect to phosphorus for photosynthetic processes in the study area, which is consistent with the assumption of phosphorus as limiting element often made for the northern Adriatic.

It is the most continental sub-basin of the Mediterranean, defined between two mountain chains: the Apennins to the west side and the Dinaric Alp and Balkans to the east. The Adriatic can be divided into three distinct sub-basins: Northern, Middle and Southern. Due to the geographical position, its orography and bathymetry, the Adriatic Sea hydrography Is strongly influenced by meteorological conditions, particularly in the north. Climatologically, temper ature variations greater than 20 degrees C are observed between winter and summer, and about 8 degrees C from north to south in winter, as well as a salinity gradient of about 3 psu (practical salinity unit) between the western coastal water and the offshore water. Interannual variability has been evident from the first systematic oceanographic observations of this sea and is remarkable. There are three principal water masses in the Adriatic Sea: the Adriatic Surface Water (AdSW), the Levantine Intermediate Water (LIW) and the Adriatic Deep Water (AdDW) (every sub-basin has its own characteristic deep water). The general circulation is cyclonic with a now towards the northwest along the eastern side and a return flow towards the southeast along the western side. The circulation in the three sub-basins is often dominated by their own cyclonic gyres that vary in intensity according to the season. The sub-gyre of the southern Adriatic tends to persist throughout the year. The sub-eyre of the middle Adriatic is more pronounced in summer and autumn, while in the north, a cyclonic gyre is evident, in front of the Po river mouth, only in autumn.</td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0214-8358</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td>DEC</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>1996</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>60</td> </tr> <tr> <td valign="top" style="width: 25px">SU </td> <td>Suppl. 2</td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td>33</td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td>43</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:A1996WL54500004</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=13"></a>AU </td> <td>Vischetti, C<br> Businelli, M<br> Marini, M<br> Capri, E<br> Trevisan, M<br> DelRe, AAM<br> Donnarumma, L<br> Conte, E<br> Imbroglini, G</td> </tr> <tr> <td valign="top" style="width: 25px">TI </td> <td>Characterization of spatial variability structure in three separate field trials on pesticide dissipation</td> </tr> <tr> <td valign="top" style="width: 25px">SO </td> <td>PESTICIDE SCIENCE</td> </tr> <tr> <td valign="top" style="width: 25px">AB </td> <td>Experiments were carried out on three Italian farms to assess the degree of spatial variation of pesticide field concentration during treatment and during dissipation trials.

The authors also define the regional climatological seasons computing the average monthly values of heat fluxes and heat storage from a variety of atmospheric datasets. The long term mean surface heat balance corresponds to a heat loss of 19-22 W m(-2). Thus, in steady state, the Adriatic should import about the same amount of heat from the northern Ionian Sea through the Otranto Channel. The freshwater balance of the Adriatic Sea is defined by computing the average monthly values of evaporation, precipitation, and river runoff, obtaining an annual average gain of 1.14 m. The distribution of heat marks the difference between eastern and western Adriatic areas, showing the winter heat losses in different parts of the basin.<br> Climatological water masses are defined for three regions of the Adriatic: (i) the northern Adriatic where Seasonal variations in temperature penetrate to the bottom; deep water (NAdDW) with sigma(t) &gt; 29.2 kg m(-3) is produced and salinity is greatly affected by river discharges; (ii) the middle Adriatic where a pool of modified NAdDW is stored during the summer season after being renewed in winter and modified Levantine Intermediate Water (MLIW) intrudes from the southern regions between spring and autumn; and (iii) the southern Adriatic where homogeneous water properties are found below 150 m (the local maximum depth of the seasonal thermocline) and a different deep water mass (SAdDW) is found with sigma(t) &gt; 29.1 kg m(-3), T approximate to 13.5 degrees C, and S approximate to 38.6 psu. Due to river runoff waters, the surface layers of all three regions are freshened during the spring-summer seasons. The vertical distributions of dissolved oxygen vary quantitatively in the three regions showing a spring-summer subsurface maximum due to the balance between phytoplankton growth in the euphotic zone and low vertical mixing in the water column. This behavior can be reconciled with open ocean conditions except for the northernmost part of the Adriatic where well-mixed oxygen conditions prevail throughout the year.<br> Large interannual anomalies of both temperature and salinity are found at the geographical center of the basin in surface and deep waters (100 m).</td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0022-3670</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td>AUG</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>1997</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>27</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>8</td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td>1492</td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td>1514</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:A1997XT23700002</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=15"></a>AU </td> <td>Artegiani, A<br> Bregant, D<br> Paschini, E<br> Pinardi, N<br> Raicich, F<br> Russo, A</td> </tr> <tr> <td valign="top" style="width: 25px">TI </td> <td>The Adriatic Sea general circulation .2.

The Adriatic Sea is divided into four regions, the northern Adriatic, in which a region shallower than 40 m and a region deeper than 40 m are distinguished, the middle Adriatic and the southern Adriatic. The basin exhibits a generally decreasing trend of nutrient concentrations from North to South, due to the nutrient input by rivers, occurring particularly in the northern Adriatic, enabling intense phytoplankton developments in winter and autumn. In the northern basin the dominant cyclonic circulation determines a southward nutrient flow along the western coast; however, the resulting horizontal nutrients distribution can be strongly affected by phytoplankton uptake, as in the case of the winter bloom. Strong bacterial regeneration of the organic matter occurs in spring-summer, with a sensible oxygen depletion and nutrient increase at depth. In the middle Adriatic the phytoplankton biomass is much lower than in the northern Adriatic, but its role in controlling the nutrients distribution is relatively more important, because of the reduced influence of river input. In the southern Adriatic the Modified Levantine Intermediate Water (MLIW) is characterized by high nitrate concentrations. However, a detailed picture of the southern basin is prevented by the lack of data. As a tentative result, the analysis of the Redfield ratios seems to confirm that, generally, the Adriatic Sea is a phosphorus limited basin, but also seems to indicate that the surface water in the middle and, particularly, the southern Adriatic might be characterized by nitrogen limitation.

Diatom maxima were observed in spring and autumn: their vertical distribution generally reflected the Chi a pattern and in the western coastal area peaks are due to large diatom species (Pseudo-nitzschia spp.). In offshore waters, dinoflagellates strongly prevail over diatoms and provide a relevant contribution to the total biomass, especially in highly stratified conditions.

This yielded 3600 new oceanographic stations, concentrated in an area where 809 ATOS stations were located. The new data were quality checked, and then a seasonal climatology was drawn up as a first analysis step. The new climatology differed significantly from the ATOS results; this could be explained, at least partially, by the climatic changes that have occurred in this area. For example, air temperature increased significantly over northern Italy starting from 1988. Variations of the observed air temperature and Po River runoff qualitatively agree with sea surface temperature and salinity variations. A preliminary computation of heat fluxes based on ECMWF reanalysis confirms an increased heat flux to the Northern Adriatic Sea starting from 1988.</tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0173-9565</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>2002</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>23</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>Supplement 1</td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td>340</td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td>351</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td></td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=23"></a>AU </td> <td>Corinaldesi, C<br> Crevatin, E<br> Del Negro, P<br> Marini, M<br> Russo, A<br> Fonda-Umani, S<br> Danovaro, R</td> </tr> <tr> <td valign="top" style="width: 25px">TI </td> <td>Large-scale spatial distribution of virioplankton in the Adriatic Sea: Testing the trophic state control hypothesis</td> </tr> <tr> <td valign="top" style="width: 25px">SO </td> <td>APPLIED AND ENVIRONMENTAL MICROBIOLOGY</td> </tr> <tr> <td valign="top" style="width: 25px">AB </td> <td>Little is known concerning environmental factors that may control the distribution of virioplankton on large spatial scales.

In order to test this hypothesis, we determined the distribution of viral abundance and bacterial abundance and the virus-to-bacterium ratio in a wide area covering the entire Adriatic basin (Mediterranean Sea). To gather additional information on factors controlling viral distribution on a large scale, functional microbial parameters (exoenzymatic activities, bacterial production and turnover) were related to trophic gradients. At large spatial scales, viral distribution was independent of autotrophic biomass and all other environmental parameters. We concluded that in contrast to what was previously hypothesized, changing trophic conditions do not directly affect virioplankton distribution. Since virus distribution was coupled with bacterial turnover times, our results suggest that viral abundance depends on bacterial activity and on host cell abundance.</td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0099-2240</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td>MAY</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>2003</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>69</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>5</td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td>2664</td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td>2673</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:000182808300030</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=24"></a>AU </td> <td>Campanelli, A<br> Fornasiero, P<br> Marini, M</td> </tr> <tr> <td valign="top" style="width: 25px">TI </td> <td>Physical and chemical characterization of the water column in the Piceno coastal area (Adriatic Sea)</td> </tr> <tr> <td valign="top" style="width: 25px">SO </td> <td>FRESENIUS ENVIRONMENTAL BULLETIN</td> </tr> <tr> <td valign="top" style="width: 25px">AB </td> <td>This paper summarises the research carried out from 2001 to 2002 in the coastal area of Piceno, NW central Adriatic Sea.

The aim of this study was to investigate early diagenesis processes that produce benthic fluxes affecting the chemistry of water column. Two oceanographic cruises were carried out in late summer 2002 and in late winter 2003 to evaluate the seasonal variations of early diagenetic processes. Sediment cores were collected in two sites (inside and in the offshore boundary of the gulf) in which high sedimentation processes occur. Parameters on the solid fraction and pore waters profiles of TCO2, NH3, NO3, PO4 3-, SO4 2-, alkalinity, Fe, Mn, Ca and Mg were determined in each site. Benthic fluxes were measured using two benthic chambers in each site. The 234Th profiles show a more intense bioturbation in the firsts centimetre of sediment in the inner station and the sedimentation rate, calculated by 210Pbex and 137Cs profiles, ranging from 0.40 gcm-2 y-1 in the inner shelf to 0.49 gcm-2 y-1 in the outer gulf. In winter, pore water profiles suggest oxic and anoxic degradation of reactive organic matter less intense and occurring in a thinner layer close to the sediment-water interface in both site Reactive organic matter degradation products also show an intense irrigation in the firsts centimetres of sediments in both stations. During the summer, the pore water profiles reflect remineralization processes limited to a very thin layer close to the sediment water interface in both stations but higher in the shallowest site. Measured benthic fluxes will be compared with the fluxes obtained by pore water modelization to investigate sedimentwater interface processes. </td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0016-7037</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td>JUN</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>2004</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>68</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>11</td> </tr> <tr> <td valign="top" style="width: 25px">SU </td> <td>Suppl.

Larger aggregates (ribbons, cobwebs, clouds, and false bottoms) formed only during late-spring and summer, particularly in 2000 and 2002, when the seasonal thermohaline stratification was marked. In fact, the process of mucilage formation took place mainly in the upper water column, above the main pycnocline.<br> The spatial distribution shows that higher concentrations of small aggregates occur in the more productive coastal waters. The larger aggregates form or accumulate mainly in coastal waters in the southern part of the NA and in the central part of the Po River delta-Rovinj transect, where a gyre greatly influences the aggregates distribution. The fronts between low salinity coastal waters and high salinity waters of southern origin play an important role for accumulation and aggregation of the mucilage during spring and summer. Most of the aggregates accumulate in correspondence with strong pycnoclines with differences in density anomaly of 2 kg m(-3) or higher. False bottoms formed in correspondence with strong haloclines (Delta S congruent to 2), while cobwebs and ribbons also occurred when the halocline was less marked (Delta S &lt; 0.5). Meteorological conditions greatly influenced the aggregate formation. Calm weather and weak winds favour aggregation processes, while strong north-easterly winds, causing intense mixing, result in the dispersion of the mucilaginous aggregates, as occurred during the Bora event in July 2000.

In this work, meteorological and oceanographic conditions in the NA during the period June 1999-July 2002 are described and their relation to the outbreak and fate of the mucilage phenomenon was investigated. Salinity and temperature data were collected during approximately monthly cruises along three transects in the NA. Relevant meteorological situations (air temperature, rainfall, wind) were selected from large-scale ECMWF analyses and from the Local Analysis and Prediction System (LAPS; Emilia Romagna Meteorological Service), while sea conditions (waves) were analysed by means of the Wave Adriatic Model (WAM). Data for air temperature, rainfall, and wind from several meteorological stations in the region were used. Average seasonal cycles of sea temperature and salinity simulated with statistical models, based on historical data collected in the NA since 1972, were used to determine thermal and haline anomalies. The monthly anomaly variability of maximum and minimum air temperatures, rainfall amount and number of rainy days did not appear to be relevant for the mucilage phenomenon outbreak. In contrast, both vertical and horizontal thermohaline gradients in the region were more developed during late spring and summer of 2000 and particularly of 2002, when the mucilage events were of greatest extent in space and time, compared to 2001 (short-lived event) and 1999 (no event). These more pronounced gradients were due to a combination of several unusual conditions: sharp heating of the sea surface in May-June, domination of eastwards transport of freshened waters formed in the Po Delta area, and intrusion of very high salinity intermediate waters originating in the eastern Mediterranean. Moreover, in winter of both 2000 and 2002 very dense and cold water formed and remained in the bottom layer until spring, contributing to increase the stratification degree of the water column. The duration of the mucilage events and their spatial distribution in the region depend strongly on meteorological changes. Recurrent anticyclonic conditions, characterized by low wind and calm sea, favour extended events in time (up 2 months in 2002). In contrast, highly perturbed weather, particularly due to strong "bora" wind, can be determined in sharp decay of the event (e.g. in July 2000). (c) 2005 Elsevier B.V.

Three transects with equidistant stations (10 km) were thus monitored monthly between June 1999 and July 2002. The geostrophic method was used to compute currents across the three transects from the CTD data, and dynamic heights provided a picture of the horizontal surface circulation. Currentmeter data records were used to adjust the reference surface and to validate the results for the southernmost and deeper (up to 70 m) transect (Senigallia-Susak Island). Geostrophic currents allowed estimation of monthly water fluxes across the transect. Different circulation regimes in the NA were observed, which may have affected mucilage events. When mucilage was absent (1999) or reduced (200 1) in the western sector, the Western Adriatic Current (WAC, carrying water out of the NA) was found to be active, whilst the WAC was very weak or reversed when massive mucilage events occurred (2000 and 2002). Opposite behaviour has been observed for the Istrian Coastal Counter-Current (ICCC, retaining freshwater water in the NA) which was more intense during or after massive mucilage events and did not appear when mucilage was absent. Both WAC weakening and ICCC strengthening indicate a longer residence time of riverine waters in the NA, which favours mucilage development. Conclusively, WAC and ICCC result as key elements in controlling massive mucilage phenomena in the NA. (c) 2005 Elsevier B.V.

Sci Total Environ 2005-this issue], with the aim to verify their possible role in the mucilage phenomenon. The nutrient transports in the northern Adriatic were very variable, seasonally and from year to year, both in intensity and direction. Some differences were noticed also among the nutrient species. At the northernmost transect Po Delta-Rovinj minimal values and variable directions were recorded, probably due to the prevailing of eastward transversal transports, observed already in late winter, and generally dominant in spring and summer. Northward transport was often measured at the central transect Cesenatico-Cape Kamenjak, particularly in spring 2000 and 2002, and summer 2001, as well as for only DIN in summer 1999. In contrast, southward directions prevailed at the southernmost transect Senigallia-Susak Island. In October significant southward transports occurred at all transects and for all nutrients, particularly strong in 2000, when exceptionally high Po River discharges occurred, and the Western Adriatic Current (WAC) was well developed. However, the nutrient transports in the upper water column were low or northwards at both transect Cesenatico-Cape Kamenjak and Senigallia-Susak Island in June and July 2000, 2001, and 2002, when the mucilage phenomenon developed, but were opposite in 1999, a year without events. The results suggest that high variations of nutrient fluxes and their ratios, in conditions of reduced water dynamics, are essential for the development of the phenomenon, rather than the absolute amounts of the nutrient inputs.

A historical dataset collected from 1980 to 1997 was extended with data from 15 oceanographic cruises conducted between 1998 and 2002 in the framework of the SINAPSI research program. The bottom water masses of the Jabuka pits are periodically renewed by Northern Adriatic Deep Water (NAdDW) at 1 to 3 yr intervals. During late winter-early spring, the new water eventually flows into the western pit and then into the central and eastern ones. During 1 yr of residence in the pits, bottom water nitrates increase 3-fold and dissolved oxygen decreases by 28% due to mineralisation processes. Some aspects of recently observed decadal climatic anomalies in the Northern Adriatic Sea, in particular the average winter sea surface warming, are revealed by the analysed dataset. Relationships were observed between these anomalies and the Eastern Mediterranean Transient (EMT), and from this (and other indirect indications) we infer that since 1999 the Adriatic Sea has re-emerged as a major source of Eastern Mediterranean Deep Water (EMDW). These findings confirm the worth of the mesoadriatic depressions as an easily accessible recording site of interannual oceanographic variations in the Adriatic basin.</td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0936-577X</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td>JUL 27</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>2006</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>31</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>2-3</td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td>227</td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td>237</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:000240721200010</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=32"></a>AU </td> <td>Dorman, CE<br> Carniel, S<br> Cavaleri, L<br> Sclavo, M<br> Chiggiato, J<br> Doyle, J<br> Haack, T<br> Pullen, J<br> Grbec, B<br> Vilibic, I<br> Janekovic, I<br> Lee, C<br> Malacic, V<br> Orlic, M<br> Paschini, E<br> Russo, A<br> Signell, RP</td> </tr> <tr> <td valign="top" style="width: 25px">AF </td> <td>Dorman, C.

Mean February winds are from a northeasterly direction over most of the Adriatic and a more northerly direction along the western coast. Wind speeds are fastest in jets over the NE coast during bora events and weakest in the mid-northwestern Adriatic. Diurnal air temperature cycles are smallest on the NE coast and largest in the midwestern Adriatic. The maximum sea-air difference is +10 degrees C on the eastern coast and near zero on the midwestern Adriatic. Boras are northeasterly ( from) wind events that sweep off Croatia and Slovenia, bringing slightly colder and drier air over the northern Adriatic. The main bora season is December to March. Winter 2002 - 2003 was normal for bora events. Synoptic-scale temporal variations are correlated over the northern Adriatic. Fastest Bora winds and highest wind stress over the northern Adriatic is concentrated in four topographically controlled jets. The strongest is the Senj Jet, while the Trieste Jet extends across the entire northern Adriatic. Between each two jets is a weak wind zone. The greatest mean net heat loss is in bora jets in the NE Adriatic, where it was - 438 W m(-2) and is weakest in the midwestern northern Adriatic, where it was near zero. Wind stress is concentrated over the NE half of Adriatic in four bora jets, while wind stress is weak in the NW Adriatic. There is significant variation in wind stress mean and standard deviation structure over the northern Adriatic with each bora event.</td> </tr> <tr> <td valign="top" style="width: 25px">SN </td> <td>0148-0227</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td>DEC 9</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>2006</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>112</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td>C3</td> </tr> <tr> <td valign="top" style="width: 25px">AR </td> <td>C03S03</td> </tr> <tr> <td valign="top" style="width: 25px">DI </td> <td>ARTN C03S03</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:000242754500002</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=33"></a>AU </td> <td>Marini, M<br> Jones, B.

During the winter, the plume was cool, low in both salinity and chlorophyll, but with higher chlorophyll concentrations occurring along the plume boundary. The plume mixed deeply in the water column in response to the strong wind forcing. The northern Adriatic and the Po plume cooled significantly during the observational period, and therefore salinity alone was the best discriminator of water mass variability. In contrast to the strong forcing of the winter period, the late spring was characterized by weak wind forcing, and below-average Po River discharge (_600 m3/s) which was about one third of the typical discharge for this 16 period. As in winter, salinity was again the best discriminator of water mass variability. The Po plume advected southward along the Italian coast and in some locations portions of the coastal plume were transferred offshore in filament-like features. However, the one observed filament was quite low in chlorophyll and was quite thin vertically, extending downward less than 5 m from the surface. The spring observations provide a distinct contrast in the effects of the physical forcings of river flow and wind stress from two different seasons. The strong winter forcing resulted in deep mixing of the plume despite its low salinity and buoyancy, whereas the weak summer flow under weak winds resulted in a very shallow plume (<5 m) that was high in chlorophyll. <tr> <td valign="top" style="width: 25px">SN </td> <td>0148-0227</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td> MAY 21</td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td>2008</td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td>113</td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td> C05</td> </tr> <tr> <td valign="top" style="width: 25px"> AR&nbsp;</td> <td> C05S90</td> </tr> <tr> <td valign="top" style="width: 25px"> DI</td> <td> ARTN C05S90</td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td> ISI:000242754500002</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td valign="top" style="width: 25px">PT </td> <td>J</td> </tr> <tr> <td valign="top" style="width: 25px"><a name="pbl=34"></a>AU </td> <td>Campanelli, A<br> Massolo, S<br> Grilli, F<br> Marini, M<br> Paschini, E<br> Rivaro, P<br> Artegiani, A<br> Jacobs, S.

The sections cross the Subantarctic Front (SAF), the Polar Front (PF) and the southern Antarctic Circumpolar Current front (sACCf). The SAF consists of two parts which have distinct thermohaline signatures: the northern part (NSAF) is associated with the temperature gradient 4-7 °C, whilst the southern part (SSAF) is associated with the temperature gradient 3-4 °C. The PF shows temperature lower than 2 °C and the sACCf temperature lower than 0 °C. Seawater samples were collected at the surface from the ship underway system in correspondence with XBT (expandable bathythermograph) launches. In the studied period the spatial evolution of surface water physical structures is coupled with the variations of nutrient concentrations. In fact the different water masses can be identified by both the temperature and the nutrient trends. In particular in the first and second section, silicic acid sharply increased from 10-15 ?M to 50-55 ?M, from 58°S to 60°S, where temperature strongly decreased from 7 °C to 2 °C. Nitrate increased more regularly moving from north to south, with concentrations ranging from 10-12 ?M at 54°S to 25-30 ?M at 66°S. The same feature was observed during the later transects but the sharp silicic acid and temperature gradients were shifted between 60°S and 64°S. The factors that determine the position of this gradient are poorly understood due to the lack of direct measurement. The last transect showed a significant decrease (or uptake) of nitrate, orthophosphate and silicic acid between 63°S and 70°S respect to concentrations monitored during the previous cruises. The average depletion of nutrient concentrations in this area is around 25 µM (37 %), 0.7 µM (44 %) and 7.4 µM (29 %) for silicic acid, orthophosphate and nitrate respectively. This decrease is probably associated with the seasonal phytoplankton bloom characteristic of this period. In fact during the early summer the N/P apparent drawdown ratio was 8.8 ± 4.1 and the Si/N apparent drawdown ratio was > 1. The nutrient ratio drawdown (N/P and Si/N) suggest that this depletion can be due to diatom group uptake. The region of the ACC is marked by an extremely strong latitudinal gradient in silicic acid concentration, which has been observed centred on the PF.<tr> <td valign="top" style="width: 25px">SN </td> <td>0924-7963</td> </tr> <tr> <td valign="top" style="width: 25px">PD </td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">PY </td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">VL </td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">IS </td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">BP </td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">EP </td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">UT </td> <td>ISI:000077494700012</td> </tr> <tr> <td style="width: 25px">ER</td> <td></td> </tr> <tr> <td valign="top" style="width: 25px">__ </td> <td>___________________________________________________</td> </tr> <tr> <td style="width: 25px">EF</td> <td></td> </tr> </table> </body> </html>
