Abstract

This is the log for the McLane pumps deployed on the R/V Atlantis CliOMZ AT50-10 expedition from Golfito Costa Rica to San Diego USA that occurred in May - June of 2023. The log contains metadata associated with each pump deployment, including location, pump depth, and time. The pumps were launched on 1/4" kevlar line spooled on a MASH2K winch from the East Coast Winch Pool. The Science party included members from WHOI, UCSB, UTGRV, and Clark University.

Seven Large Volume Water Transfer Systems (McLane pumps) were deployed during research cruise AT50-10 attached to a synthetic wire using a MASH2K winch and a dual filter sampler system. Deployments lasted 3 or 4 hours and seawater was filtered at specific depths. A combination of 0.2 um Supor membranes and 51 um pore size Nitex mesh was used for one side while the other side pump water through a Glass Fiber Filter (GFF). See data log for specific size fraction combination as well as specific samples taken.
