Ageing of Crustaceans Carbon Cycling and Climate Change in the Arctic Approaches are being developed and used for biochemical ageing of crustaceans like the Maryland Blue Crab Molecular biomarkers are used to analyze the sources and fate of organic carbon in the western Arctic Ocean Photo courtesy of SERC Photo courtesy of Rebecca Levy Lipids and Food Webs in Marine Ecosystems Protein Cycling and Modification Lipids are used to examine the physiological condition of organisms and food web dynamics in marine ecosystems How are proteins preserved in the geological record? Bacterial Diversity and Lipids Research Facilities Lipid distributions of naturally occurring bacterial assemblages and the interactions of bacteria with organic carbon are examined
