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. |
