St Lucia – Africa’s Largest Coastal Lagoon - Quaternary history and effects of global change: Papers 1-3
MetadataShow full item record
St Lucia, is a large coastal lagoon, which is very sensitive to changes in water level,volume and quantities of inflowing freshwater. It is therefore sensitive to the effects of global change that alter sea levels and rainfall. Earlier studies have shown that, during the Eemian, St Lucia was a marine environment. At that time global sea level was 3-4 m higher than that at the present. During the falling sea level leading up to the Last Glacial Maximum, St Lucia was above sea level and the climate was mainly dry. Studies of cores at Brodie’s Crossing showed that there were episodes with a wet climate at 23 000 years BP. During this period peat was deposited. Overlying this is wind-blown sand. Diatom studies indicate that this overlying sand was mainly redeposited Eemian marine sediments. Studies of the effects of future global change have focused on three ecosystems: the estuary itself, the Eastern Shores, and the Eastern Shores–lagoon interface (Brodie’s Crossing). For the estuary.....
