Lake Vanda  is in the Wright Valley and a lot bigger than Lake Joyce with a length of around five km. It is also ice-covered but the ice is in average only 4 meters thick. Lake Vanda is meromictic, which means that the deeper layers never mix with the upper layers. This creates very different condition in the shallower and deeper parts of the lake, and therefore very different microbes will likely be found in the different sections of the water column.

 

Lake Ice

In contrast to Lake Joyce the lake ice is very smooth with millions of fine cracks and trapped bubbles, creating amazing patterns and shapes.
