Sensors & Samplers
McLane Large Volume Water Transfer Systems are designed to collect particulate matter, in-situ, in support of oceanographic research projects and environmental monitoring programs.
MOCNESS is a much-improved, high-tech version of the humble sampling net. The letters in MOCNESS refer to the specific improvements: it's a Multiple Opening and Closing Net, with an Environmental Sensing System.
The piston corer is a long, heavy tube plunged into the seafloor to extract samples of mud sediment. A piston inside the tube allows scientists to capture the longest possible samples, up to 90 feet in length.
BGM-3 gyrostabilized marine gravimeters are provided to the UNOLS community through the 'Potential Fields Pool Equipment' (PFPE) section. PFPE provides hardware spares, maintenance and troubleshooting support for the BGM-3 gravimeters for all UNOLS ship operations groups.
Probably the most commonly used water sampler is known as a rosette. It is a framework with 12 to 36 sampling bottles clustered around a central cylinder, where a CTD or other sensor package can be attached.
Scientists use the ROV Rock Drill System to obtain multiple high-quality samples in the form of short (~2-100 cm) cores. The ROV Rock Drill System was developed by the Monterey Bay Aquarium Research Institute (MBARI). NSF awarded a grant to WHOI scientists to purchase the system from MBARI and provide operational oversight and coordination to allow it to be used by U.S. investigators.
SID is a robotic mini-laboratory that automatically collects and processes seawater samples for researchers interested in studying biological activity in the deep ocean.
The Video Plankton Recorder (VPR) is an underwater video microscope system that that takes images of plankton and particulate matter as small as 50 microns and up to a few centimeters in size.
