Pony Lake

Pony basin, Ross Island      Waterbody ID: 19

 

Description

Pony Lake on Ross Island is located on Cape Royds. It is a shallow pond ~120 m long, 70 m wide, and 1-2 m deep. Huts built by Shakleton's expedition of 1908 face the southern end of the pond. The eastern shore of Pony Lake is adjacent to a penguin rookery and the pond has high nutrient concentrations. High levels of Na, Cl, and SO4 are probably due to the marine influence. The water is well mixed by strong winds that prevail at the cape.
