| Abstract | The RV METEOR research cruise M140 combined sampling in the water column with recovery of data and samples from long-term observational platforms (sediment traps and dust collecting buoys) with the aim to provide data necessary to understand the ecology of planktonic foraminifera and the investigate how marine particle flux, mineral dust deposition and production of biomineral particle ballast varies in space and time and how they affect the marine biological pump. The cruise covered a transect from low productive offshore regions to high-productivity coastal upwelling in the central western Atlantic. Though multibeam has been recorded during the cruise, it was not a major focus and the responsible party provided no acquisition information. |
