Biogenic Silica and Carbon 14 Age Dates from Lake Victoria Cruise V95 Cores

Description

The LLO operates in conjunction with the Limnological Research Center (LRC) in working towards fulfilling the objectives of the International Decade for the East African Lakes (IDEAL) to study the East African Lakes. The Lake Victoria project is funded by NSF. Like Lake Victoria, extensive work is being continued on Lake Malawi, Lake Turkana, and Lake Edward. In addition to the East African lakes, the LLO is working on Lake Issyk Kul', Lake Nicaragua, and Lake Superior. Summary: The Biogenic Silica Data file contains data for 5 cores taken from various sites in Lake Victoria. The data include ship, coring date, water depth, latitude/longitude, sampling device, sampled interval, % biogenic silica, and 14C dates. Cores were sampled at 10 cm intervals for biogenic silica analysis. Samples taken for 14C dating were prepared at the LRC Laboratory and sent to an outside AMS Facility for analysis. Pollen, charcoal, and plant macrofossils were dated. Biogenic Silica analysis was done using a timed, wet extraction technique adapted from D. J. DeMaster (1979). The analysis was done using 0.5 M NaOH at 85 0C.
