The ProteOMZ Expedition: Investigating Life Without Oxygen in the Pacific Ocean

Project description:Untargeted proteomics from a 5,000 km+ transect across the central Pacific Ocean from Hawaii to Tahiti. The expedition crossed multiple biogeochemical provinces, inlcuding the oligotrophic North Pacific Subtropical Gyre, the extremety of the Eastern Tropical North Pacific Oxygen Deficient Zone, and the relatively productive equatorial region associated with upwelling. This dataset focuses on the microbial fraction (0.2-3.0 micrometer filter size) and the microbial community dynamics across these biogeochemical provinces, from the surface oceance to the mesopelagic (1,250 m depth maximum).

Dinoflagellates contribute to primary and secondary production across biogeochemical gradients of the central Pacific Ocean

Project description:In this study we explored the metabolism of unicellular eukaryotic organisms (protists) across a 4,600 km meridional transect in the central Pacific Ocean. The region contains a natural biogeochemical gradient spanning from low nitrogen, oligotrophic waters to a productive equatorial upwelling system. We used a combined geochemical and 'omic approach to characterize the metabolic strategies these organisms rely upon to adapt to changes in their chemical environment. Samples were collected using underwater pumps, capable of filtering hundreds of liters of seawater, from seven stations and 3-13 different depths spanning 20-1,900 m in the water column.
