The total B activity shows a small peak around 15 m but 13 Cs activity is below the detection limit in all the samples. The lead 210 activity indicates an average fallout in the range1 1 ? 03 dpm/L in various samples. The vertical profile of 88 O in 3 m ice core ranges between-17 2 to-21 5/o indicating a mean annual surface air temperature of 9 C at the time of deposition. Natural thermoluminescence levels of the trapped dust are smaller than the geological levels consistent with data obtained earlier. Shallow ice core samples were collected near Dakshin Gangotri Station, from a location situated40 km inside the shelf, by the second Indian Expedition to Antarctica during January February1983. The samples were brought in frozen condition to Goa and then air lifted to Physical Research Laboratory, Ahmedabad in specially fabricated boxes (cooled by dry ice) for analysis. The ice samples were studied for natural and artificial radio activity, 3 Cs,2 Pb, Stable Isotope 8 8O and Thermolumincscence (TL) of trapped dust m ice layers. These data are compared with the findings insamples collected by the first Indian Expedition to Antarctica (Bhandan et al 1984) Completed Dr. V N Nijampurkar National Centre for Polar and Ocean Research (NCPOR) 8322525515 Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Principal investigator Earth Science-Cryosphere Theme Dakshin Gangotri Antarctic Place Isotopic and TL Studies of Antarctic Ice Samples Project English 20.0 140.0 -90.0 30.0 1982-01-01 1983-12-31 TableDigital Cryosphere unknown Mr. Sakthivel Samy V National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Distributor http://npdc.ncaor.gov.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF1700187895&userType=user&freeTextValue=Isotopic+and+TL+Studies+of+Antarctic+Ice+Samples.
