Studies on the anaerobic sediments and underlying cyanobacterial mats from the McMurdo Ice Shelf
Entry ID: K081_1996_2000_NZ_2

Abstract: The pond ecosystems of the McMurdo Ice Shelf contain abundant growths of algae and cyanobacteria. The role of the anaerobic sediments underlying the cyanobacterial mats was investigated. Sediment samples were collected from several ponds to determine in situ rates of methanogenesis, methane oxidation and ammonium turnover. Sub-samples were used to determine sulfate reduction. All experiments were ... View entire text
