Sažetak
Phytoplankton growing in the surface ocean fuel the biological pump: the organic carbon produced by phytoplankton can be removed from the atmosphere and naturally sequestered in the deep ocean through complex ecological and physical processes. The mechanisms leading to the transport of phytoplankton and the organic carbon they produce must be better resolved to improve quantification and prediction of the ocean carbon cycle. We deployed a combination of drifting sediment trap platforms (~150 m deep) and sensors at three locations in the open North Pacific Ocean to identify 1) which phytoplankton from the surface were contributing to carbon export and 2) the mechanism leading to their transport. The three sampling locations spanned ecosystems in the oligotrophic subtropical gyre to the coastal upwelling-influenced coast of California. A subset of sediment trap tubes contained a polyacrylamide gel layer, which was imaged and analyzed by microscopy to enumerate individually-resolved particles and organisms. The organismal contents of individual particles isolated from the gel (i.e fecal pellets or aggregates) and from the surface waters will be determined using molecular sequencing tools. Our preliminary data indicate large shifts in the surface community among these locations, corresponding with an order of magnitude difference in particle fluxes and changes in the dominant phytoplankton and particles responsible for carbon export.
