WHOI Pump Facility

The WHOI Pump Facility manages requests for the use of NSF-funded McLane Water Transfer Systems (WTS). These in situ pumps are designed to collect suspended and dissolved particulate samples onto a 142 mm filter. They were designed for use from the ship’s hydro-wire.

As single-event samplers, they can process large volumes of water, up to 5,000 L. WTS units can be programmed for flow rates ranging from 1 to 8 L/min and for a specified total sample volume, with sampling initiated either after a countdown delay or at a scheduled time.

The current inventory includes 14 WTS units (LV-08), available in vertical or horizontal configurations, for in-situ particulate matter collection using radial intake, vertical intake, or cartridge sampling. Three of these pumps are designated specifically for zooplankton collection.

To request use of the WTS in-situ pumps please fill out the “In-situ Pump request” form. The requests will be prioritized by a first-come, first-serve basis. If there is a conflict with equipment reservations, priority will be given to projects using the assets aboard UNOLS vessels. It is suggested the user participate in a refresher course to familiarize yourself with the operation of the instrument before use aboard a research vessel.

Before submitting a request use of the WTS pumps maintained by WHOI, please review the Use of Shared Equipment policy.
