The cycling of sulfur in marine biogeochemical cycles plays an important role in regulating the redox state of the Earth's atmosphere and ocean.
While the broad outlines of phosphorus cycling in the ocean are known, a mechanistic understanding of P cycling is lacking.
Due to its extreme size and remoteness, the surface waters of the South Pacific Subtropical Gyre are the most oligotrophic in the global ocean.
In the project “EreBUS” biogeochemical processes on a transect through the Benguela Upwelling System and Angola Gyre were studied.
