Benthic mat biomass and productivity (photosynthesis and respiration) in Lake Vanda, Wright Valley and the role of invertebrates in carbon cycling in the lake
Entry ID: K081_1997_2000_NZ_1

[ Update this Record ]

Summary
Abstract: The importance of benthic microbial production in the lakes of the McMurdo Dry Valleys and how the benthic cyanobacterial mats are adapted to survive and grow in deep water (extreme low light but no freezing) was investigated. Quantity and quality of light penetrating the ice and light attenuation properties of the water column were determined. Samples of benthic mat cores were collected for ... View entire text
