Project information
Project aim
Marine sediments are important regulators in global biogeochemical and atmospheric cycles. Recent data obtained from anoxic sediments of marine-derived Antarctic lakes indicates the presence of a highly diverse range of bacteria whose biogeochemical roles remains largely unknown and which inhabit continually low temperature habitats. An integrated molecular and chemical approach will be used to investigate the coupling of microbial biogeochemical processes with community structure and cold adaptation within coastal Antarctic marine sediments. Overall the project expects to make an important contribution to our understanding of evolutionary processes within low temperature habitats and the subsequent conclusions will have wide applicability to studies examining other benthic and cold-adapted ecosystems.

Oxyphotobacteria ascribed to the genera Synechococcus and Synechocystis are widely distributed in Arctic and Antarctic lakes, yet they are poorly represented in the marine polar environment. Arctic lakes contain phycoerythrin-rich as well as phycocyanin-rich … picoplankton…
