Organic Lake [SEP] continent
Organic Lake
Organic Lake is a lake in the Vestfold Hills in eastern Antarctica. It was formed 6,000 years ago when sea levels were higher; it is isolated, rather shallow (7.5m), meromictic, a few hundred meters in diameter and has extremely salty water. It has the highest recorded concentration of dimethyl sulfide in any natural body of water.
In 2011, a new species of virophage (a satellite virus that impairs the ability of its co-infective host virus to replicate) was discovered in Organic
high insolation levels. This explains both the transgressive event recognised at the margins of the Old Red continent, caused by thermal expansion of the oceans, and the formation of the Achanarras lake within the continent due to the increased intensity of monsoon conditions.
Extinctions.
The Kačák Event was a period of significant extinctions, although not as marked as those of the subsequent Late Devonian extinctions. The group most affected was the Ammonoidea, although there were also faunal turnovers amongst conodonts and dacryoconarids.
