Lake Miers, South Victoria Land, Antarctica

摘要: Abstract The morphology, physics, and chemistry of Lake Miers (78° 07′ S, 163° 54′ E), a warm freshwater Antarctic lake, are discussed. presence rock debris on the floating lake ice has led to formation dirt cones melt pools. Fossil levels these pools show that annual ablation is 15–20 cm. Despite mean air temperature − 20 ° c, bottom waters at + 5 C. This shown be natural example solar heat storage observed profile satisfactorily accounted for. Chemical evidence suggests been filled by containing K, Na, Cl, O2 , it now stagnant below 4° C depth. In this lower zone Ca, Mg, CO2, SiO2 diffusing upwards from bed, possibly partly released anaerobic biological activity.
