Figure 9. The WTS-Tr sediment sampling system (pump head and controller) mounted within an ocean bottom-resting tripod typically used for Massachusetts Bay deployments. The tripod also holds additional instruments that measure: currents, temperature and salinity, pressure (waves), light transmission, and still cameras for photographing the ocean bottom. The tripod typically remains on the ocean bottom for 3 to 4 months collecting oceanographic data on tidal currents and storm generated resuspension events.
