| Summary: | In situ data obtained from CTD (Conductivity, Temperature, and Depth) sensors attached on 5 elephant seals (Mirounga Leonina) that crossed the Argentine Continental Shelf (ACS) between the 17th and 31st of October 2019 are analyzed. The analysis of the temperature and salinity along the trajectories allowed us to identify two different regions: north and south of 42°S. In the north-ern region, the temperature is 1°C warmer and 0.5 saltier than in the southern region. Sub-surface (15 m depth) in situ data collected correlates very well (r=0.9) with satellite sea surface tempera-ture (SST) data. The SST pattern observed suggests that north of 42°S warm waters are coming from the San Matias Gulf (SMG). Temperature-Salinity (TS) diagrams allowed to clearly identify Malvinas Water, Low Salinity Coastal Water, Mid-Shelf Water, and Water with High Salinity Coastal Water from SMG. The latter water mass was observed only in the northern region and the other three were present in both regions. The high spatio-temporal ... |
