Estimates of suspended sediment yield over the past 800 years have been derived from a whole-basin study of lake sediments in Llyn Geirionydd, North Wales. Magnetic and physical sediment properties were used to correlate a suite of cores to a master
Masterful synthesis of mountain environments in Africa from Kenya to Morocco over the last 20 000 years. Climatic change about 18 000 B.P. had a major impact on vegetation. In the past 2 000 years anthropogenic processes, combined with greater
