The Lake Vanda is an endorheic lake in Wright Valley in East Antarctic Victoria Land . The New Zealand Vanda Station was on its bank from 1968 to 1995 .


The lake is 8 km long and 2 km wide with a maximum depth of 75 m. The Vandasee is a hypersaline lake with a salt content of approx. 12 percent by weight and is meromictic : the deeper layers of the lake do not mix with the upper layers. It is just one of the many saline lakes in the ice-free valleys of the Transantarctic Mountains . The largest river in Antarctica, the Onyx River , flows west (inland) into the Vanda Sea. There is a meteorological station at the mouth of the river. There are no fish in Onyx and Lake Vanda, only microorganisms.

Vanda station

The Vanda station was known for the "Royal Lake Vanda Swim Club". Visitors to the Vanda station could bathe in the salty water when the ice at the edge had melted in summer, and in return received a sleeve patch from the Royal Lake Vanda Swim Club. The station staff speeded up the melting process by chopping the ice up into a pool. Many dignitaries and politicians were admitted to the club, but had to be naked in the bath (rule 1), had to submerge completely (rule 4) and by a "vandal" (employee of the Vanda station) without restrictions on a photo evidence (rule 6) testify to qualify. Rule 10 permitted wearing a real fig leaf .

In the colder months the rim froze again to a usually crystal-clear, meter-deep ice.

When the lake's water level rose, the Vanda station was removed in 1995 and replaced with another accommodation ( Lake Vanda Hut ). This is periodically manned by two to eight researchers in summer.
