Primary Productivity, Phytoplankton Standing Crop and Physico-Chemical Characteristics of the Antarctic and Adjacent Central Indian Ocean Waters. 2020-09-09T00:00:00 creation Document digital Primary productivity, phytoplankton pigments and physico-chemical properties were studied in Antarctic waters and adjoining Indian Ocean between 11? and 67?E longitudes from polynya region (60?S) to equator during the austral summer season viz. 4th January to 23rd March, 1990. The higher concentration of dissolved oxygen (11.33 mg L-1) due to photosynthesis was observed. The temperature was low (-2.0?C to 2.1 ?C) in the coastal ice-edge zone. Often, temperature recorded above zero, lowered the salinity from 34.9 to 33.16 x 10-3. Gradual increase of temperature (-0.8 - 29.0?C) and salinity (33.19 - 36.27 x 10-3) and decreasing trend of DO (av. 9.78 - 4.12 mg L-1) from Polynya towards equator showed an ascending and descending order of these properties from high latitude towards low latitude. The Southern or the Antarctic ocean, with its unusual combination of the environmental condition is reported (E1-Sayed and Taguchi, 1981, Matondkar et al., 1983, Pant, 1986, Naqvi, 1986, Verlencar and Parulekar, 1987, Goes et al., 1988 and Verlencar et al., 1990) to support a fairly enhanced level of phytoplankton biomass and primary productivity. However, the factors responsible for limiting the primary productivity are not well understood. It necessitates to take up the studies on phytoplankton pigments, primary productivity and physico-chemical parameters in different regions of Antarctica and adjoining areas so as to get a better understanding of the food web dynamics and controlling factors in primary productivity. completed principalInvestigator National Centre for Polar and Ocean Research (NCPOR) 8322525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Dr. M Jiyalal Ram oceans 20.0 140.0 -90.0 30.0 1989-01-01 1990-12-31 Earth Science-Oceans Theme Maitri Antarctic Place Primary Productivity Project eng TableDigital unknown unknown unknown distributor National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Mr. Sakthivel Samy V http://npdc.ncaor.gov.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF57376294&userType=user&freeTextValue=Primary+Productivity%2C+Phytoplankton+Standing+Crop+and+Physico-Chemical+Characteristics+of+the+Antarctic+and+Adjacent+Central+Indian+Ocean+Waters.
