Radiocarbon dating of east african lake levels

Diatom frustule-bound carbon isotopes offer an original tool in examining long-term fluctuations in a lake's carbon budget and how the balance between supply and demand has changed through time.

Several years of study have gone into this page to present a (hopefully) unbiased examination of the issue of global warming.

The carbon cycle of a lake is a balance between supply from the atmosphere and catchment, and the net demand exerted by primary producers, minus losses back to the atmosphere and to sediment storage.

The most common off these, herein called the reflection seismic-radiocarbon method (RSRM), combines estimates off short-term sediment-accumulation rates derived from radiocarbon-dated cores and depth-to-basement estimates derived from reflection-seismic data at or near the same locality to estimate an age to basement.In East Africa at the same time the small lakes in the Kenya rift valley rose to combine or to create riverain links over the normal watersheds, while to their north Lake Rudolf reached a height sufficient to help feed the White Nile system.
