Instrument: Pump surface
A source of uncontaminated near-surface seawater pumped onto the deck of the research vessel that can be sampled and analyzed. This pumped seawater supply is from an over-the-side pumping system, and is therefore different from the vessel underway seawater system.
The ROCA Surface Pump is a modified impeller bilge pump system that brings large volumes of surface seawater onto the deck of the ship for sampling and processing.
