Instrument: McLane Pump
McLane pumps sample large volumes of seawater at depth. They are attached to a wire and lowered to different depths in the ocean. As the water is pumped through the filter, particles suspended in the ocean are collected on the filters. The pumps are then retrieved and the contents of the filters are analyzed in a lab.
Marine particles were collected by in-situ filtration along a ~8000 km transect that includes greater than 4000 km of hydrothermally influenced waters. Samples were filtered using a custom manifold attached to the deployed dual-flow McLane pumps.
