The McMurdo Dry Valleys Long-Term Ecological Research(LTER) project is an interdisciplinary study of the aquatic
and terrestrial ecosystems in a cold desert region of Antarctica. The McMurdo Dry Valleys, the largest ice-free area (approximately 4,800 square kilometers) on the antarctic con-tinent, are located on the western coast of the Ross Sea (77 ° 00'S 162 ° 52'E). The McMurdo Dry Valleys LTER si...

| Summary: | and terrestrial ecosystems in a cold desert region of Antarctica. The McMurdo Dry Valleys, the largest ice-free area (approximately 4,800 square kilometers) on the antarctic con-tinent, are located on the western coast of the Ross Sea (77 ° 00'S 162 ° 52'E). The McMurdo Dry Valleys LTER site (cur-rently research is focused in Taylor Valley) is far colder and drier than any of the other 17 established LTER sites. The perennially ice-covered lakes, ephemeral streams, and exten-sive areas of soil within the valleys are subject to low tempera-tures, limited precipitation, and salt accumulation. The dry valleys represent “end-member ” environments that contain microbial-dominated ecosystems. An important aspect of the McMurdo LTER research is its potential contribution to gen-eral ecological understanding through studies of processes that may be better resolved in these relatively simplified |
