Developed by Mike Gregg, this towed system measures ocean properties in a sawtooth pattern behind a ship. It carries a large suite of sensors including up and down-looking ADCP's, redundant temperature and salinity sensors, and a microstructure package. An altimeter allows us to profile close to the bottom without running into it.

Developed by John Toole (WHOI) and commercialized by McLane Research Labs, this instrument makes repeated vertical traverses of the water column along a conventional subsurface mooring wire while carrying a CTD and an acoustic current meter. We have recently been pushing its limits by sampling extremely fast to study internal waves - and have been modifying the profilers to crawl faster and carry more instrumentation such as nitrate and the Nortex Aquadopp velocity profiler.
