B11E:
Microbial Carbon Cycling and Organic Proxies in the Continental Margin: Linkages with Global Change Posters


Session ID#: 7748

Session Description:
Microorganisms play fundamental roles in global carbon cycle, particularly in continental margins that contain the vast majority of organic carbon. Global change has inevitably altered continental and marine environments in which microbial and biogeochemical processes driving the carbon cycle need to be reevaluated. This session encourages contributions on pressing topics related to plankton productivity, organic carbon transformation by archaea and bacteria, nitrification performed by ammonia oxidizers, denitrification performed by annamox bacteria, and methane cycling performed by methanogens and methanotrophs. These processes are expected to occur in diverse environments such as coastal wetlands and estuaries, hypoxic zones, gas hydrate-impacted marine sediments, and the open water affected by stratification. We also encourage topics using organic proxies and genomic tools used in addressing these questions.
