The Masoko crater-lake in southern
Tanzania provides a continuous record of environmental changes covering the last 500 years. Multi-proxy studies were performed on a 52 cm sediment core retrieved from the deepest part of the lake. Magnetic, organic carbon, geochemical proxies and pollen assemblages indicate a dry climate during the ‘Little Ice Age’ (AD 1550– 1850), confirming that the LIA in eastern Africaresulted in marked and synchronous hydrological
changes. However, the direction of response varies between different African lakes (low versus
high lake-levels), indicating strong regional contrasts
that prevent the clear identification of climate
trends over eastern Africa at this time.
Inferred changes in Masoko lake-levels closely
resemble the record of solar activity cycles,
indicating a possible control of solar activity on
the climate in this area. This observation supports
previous results from East African lakes, and
extends this relationship southward. Finally,
anthropogenic impact is observed in the Masoko
sediments during the last 60 years, suggesting that
human disturbance significantly affected this remote
basin during colonial and post-colonial
times. |
