Provedor de dados: 20
Autores: Negri, R.M.; Carreto, J.I.; Benavides, H.R.
During the spring (H-04/82: october 11-27, 1982)carried out by the Fishery Research Vessel "Dr.E.Holmberg", the distribution of temperature, salinity, nutrients concentration and photosynthetic pigments were studied at the "Rio de la Plata" maritime front. The presence of Sub-Tropical coastal waters in only station did not allow its characterization. Low Chlorophyll a concentration were noted, in association with scarce concentrations of nutrients and high Margalef index values.

The distribution, abundance and population structure of Illex argentinus in relation to the oceanographic conditions during summer 1997, were analyzed as a result of the research cruise carried out by R/V Shinko Maru No.3 on the Argentine shelf (39-50°30'S). Besides, abundance and biological features of Ommastrephes bartrami are analyzed. The main activities carried out during the cruise included jigging operations, tagging (only for I. argentinus) and biological sampling. In addition, meteorological and oceanographic data were collected. A total of 30,2000 individuals were tagged and released. The recapture rate was 0.156.  (47 recoveries/30,200 released), considerably higher than that of 1996 (0.030; 4 recoveries/13,191 released). I. argentinus was...

Oceanographic conditions at the southern end of the argentine continental slope
Provedor de dados: 20
Autores: Guerrero, R.A.; Baldoni, A.G.; Benavides, H.R.
The characteristics of the upper Antartic Intermediate water (AAIW) entering the Southern Atlantic are described on the base of oceanographic data collected from four late austral winters (1978-1980-1994-1995). The upper 500 meters regime along the shelf break and around Malvinas Islands (48° to 55° S) is analyzed. In particular, the 1994 horizontal distribution of temperature, salinity and density was mapped in order to show the extreme winter pattern of these parameters. Three salinity sections crossing the water flow direction in the Malvinas Channel (South to the islands) were selected to describe the vertical stratification 1995 and 1995. Horizontal and vertical distribution of chlorophyll a from the 1995 cruise is presented as reference data,...
