Piston cores from northern Lake Turkana in Kenya contain                   strong cyclic records of carbonate abundance and lamination                     thickness.  One of these cores has been radiocarbon dated and                   shows several strong cycles (significant at the 95% confidence                  interval) in the range of decades to centuries.  The proposed                   research on cores from this lake has two primary objectives:                    first, to determine the climatic and limnological significance of               the cycles and second, to determine the phase relationships of                  the various cycles relative to one another and to the present                   day.  Field work will entail deployment of a sediment trap, and                 collection of freeze and piston cores, and filtration of water                  samples.  The significance of this research is that Lake Turkana                sediments provide a unique opportunity to:  (1) gauge the cyclic                behavior of climate in sub-Saharan east Africa for a period of                  4000 years with unusually high temporal resolution, and (2)                     assess man's impact on climate in this region of Africa with the                perspective of 4000 years of historical record.
