CHEMICAL AND PHYSICAL ANALYSIS OF LAMINATED SEDIMENT FORMED IN LOE POOL, CORNWALL
… lamination and the palaeo-redox condition of the lake at that time. From this information a hypothesis of the formation of the laminated sediments in Loe Pool is proposed. It is suggested that a dominant factor controlling sediment composition was the redox conditions at the time of deposition. …

STRATIGRAPHIC FRAMEWORK AND QUATERNARY PALEOLIMNOLOGY OF THE LAKE TURKANA RIFT, KENYA
<p>Lake sediments are some of the best archives of continental climate change, particularly in the tropics. This study is focused on three ~10m sediment cores and high-resolution seismic reflection data from Lake Turkana in northern Kenya. Lake Turkana is the world's largest desert lake and the …

Investigations on rainfall variability during the late Quaternary based on geochemical analyses of lake sediments from tropical and subtropical southern Africa
… investigations on sediments from two African lakes which have been recording changes in their surrounding environmental and climate conditions since more than 200,000 years. Focus of this work is the time of the last Glacial and the Holocene (the last ~100,000 years before present [in the …

Sediment-Pore Water Chemistry of Taupo Volcanic Zone Lakes and the Effect Trophic State has on Exchange with the Water Column
… Island of New Zealand and contains many volcanic lakes of diverse history, physiography, and limnology. The lakes vary in size (0.2 to 620 km2), mixing regime (monomictic and polymictic), and trophic status (oligotrophic to supertrophic). The purpose of this study is to develop an understanding of …
