Two glacial-interglacial cycles (ca. 250,000 years) of climate and ecosystem dynamics on the East African equator.
DeepCHALLA is a research project centred around a c.210-meter thick sediment record from the bottom of Lake Challa, a 92-meter deep crater lake on the border of Kenya and Tanzania. These sediments contain an especially long and continuous record of the past environment of East Africa.
The project seeks to extract high-quality proxy data on climate change and landscape history over the past 250,000 years. This will significantly enhance our understanding of tropical climate and ecosystem dynamics and improve computer models for long-term climate prediction.
Developing a palaeoenvironmental archive for the last 50,000 years from rock hyrax middens of southern Africa.
The HYRAX project aims to revolutionise our understanding of environmental change in southern Africa by developing sites, proxies and methods, based on hyrax midden deposits.
The resulting data will permit the analysis and integration of palaeoenvironmental datasets spanning the last 50,000 years, revealing detailed information about past climate and vegetation dynamics in the region.
