MG54A:
Hydrocarbon Seepage as a Conduit Connecting Deep Subsurface Sediments, Shallow Sediments, the Water Column, and Atmosphere II Posters


Session ID#: 9570

Session Description:
Cold seeps are broadly distributed along active and passive continental margins. At these seeps, hydrocarbons migrate from shallow or ultra-deep reservoirs through fault networks that penetrate sediment packages, releasing hydrocarbons from the seabed through slow, diffuse seeps as well as high flow vents. Hydrocarbons are transformed biologically within the sediments during transport and after release into the water column. Hydrocarbon exposure affects patterns of microbial community structure and activity in sediments and the water column. Additionally, these fluxes also can promote physical mixing, potentially altering nutrient and material fluxes through the water column. Water column processes serve as the final biological filter than can consume hydrocarbons ranging from simple gases (e.g., methane) to petroleum (e.g. alkanes and polycyclic aromatic hydrocarbons), and prevent them from reaching the sea surface and atmosphere. Nonetheless, the patterns, rates and regulation of microbial hydrocarbon oxidation in sediments and the water column remain poorly constrained. This session will highlight recent advances in hydrocarbon dynamics at cold seeps, including the geological, physical, biological, and environmental factors that regulate the fate of hydrocarbons in oceanic environments. This session will target an interdisciplinary audience to provide a holistic understanding of hydrocarbon cycling in sediments and waters across diverse systems.
