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.[1][2]

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 Lake, the Organic Lake virophage. It is a parasite of a phycodnavirus, a large virus that infects algae and belongs to the nucleocytoplasmic large DNA viruses.[1]
