Why the interest in diving in frigid Lake Untersee in Queen Maud Land?
There’s not much in the ice-covered lakes in the McMurdo Dry Valleys to interest anglers looking to land the big one. But for scientists who want to know more about some of Earth’s earliest organisms — and, by extension, to recognize what life may look like on other planets — those unique ecosystems represent a useful portal to the past. Indeed, the lack of fish or other animals high on the food chain has allowed the microorganisms that live within the lakes to flourish unmolested, developing into communities thick enough to accumulate in layers on the lake bottoms.

Queen Maud Land is an English translation of Dronning Maud Land, the official name in use by Norwegian authorities and British Antarctic Survey on the part of Antarctica claimed by Norway as a dependent territory, on 14 January 1939. This claim, like all others in the Antarctic, is not universally recognized and is subject to the terms of the Antarctic Treaty System. It has a land area of approximately 2.5 million square kilometers (one million sq mi), mostly covered by the Antarctic ice sheet lying between the British claim, at 20°W and the Australian claim, at 44°38’E. Norway has not officially elaborated as to the northernly and southernly extent of their claim. This explains why the Norwegian claim is illustrated differently from other claims on some maps of Antarctica. It is however generally assumed that the Norwegian claim follows the norms of the other Antarctic claims. The Norwegian claim has been officially recognised by Australia, France, New Zealand and the United Kingdom.[
The ice-covered lakes of Antarctica’s McMurdo Dry Valleys have long been of interest to astrobiologists. These remote and extreme environments harbor unique microbial ecosystems that could provide clues about how life might survive on other worlds – such as Jupiter’s icy moon, Europa. Recently, a team of scientists funded by the NASA Exobiology Program began exploring the unique habitat of the ice-crusted Lake Joyce. Lake Joyce is of special interest, because it’s waters harbor carbonate structures known as microbialites. These unique structures are formed with layers of cyanobacteria. The research team is interested in how these organisms are able to grow in the dark, cold waters of Lake Joyce.
