Identifying And Tracking Proteins Through The Marine Water Column: Insights Into The Inputs And Preservation Mechanisms Of Protein In Sediments, Eli K. Moore, Brook L. Nunn, David R. Goodlett, H. Rodger Harvey

OES Faculty Publications

Proteins generated during primary production represent an important fraction of marine organic nitrogen and carbon, and have the potential to provide organism-specific information in the environment. The Bering Sea is a highly productive system dominated by seasonal blooms and was used as a model system for algal proteins to be tracked through the water column and incorporated into detrital sedimentary material. Samples of suspended and sinking particles were collected at multiple depths along with surface sediments on the continental shelf and deeper basin of the Bering Sea. Modified standard proteomic preparations were used in conjunction with high pressure liquid chromatography-tandem …
