Physical and Bio-Optical Profile Transects


Physical data collection: There are two towed systems as show above. A Small Water Area Twin Hull (SWATH) vehicle designed by GoldCoast Yachts and constructed by Rutgers is used to tow an RD Instruments Acoustic Doppler Current Profiler (ADCP) off the starboard side of the Caleta. The ADCP provides current profiles from top to bottom.
Towed behind our research vessel is a Guildline "Minibat" undulating tow-body equipped with a Falmouth Scientific Inc. (FSI) Conductivity Temperature Depth (CTD) sensor, a Wetlabs Fluorometer, and a D&A Instruments Optical Backscatter Sensor (OBS). The "Minibat" uses wings to fly between the surface and the bottom to provide full water column profiles of temperature, salinity, waterclarity and biological fluorescence.

Bio-Optical data collection: The comprehensive ) optical instrumentation package aboard the R/V Walford (aka the Waldorf Astoria) includes a Wetlabs AC9 (absorption and attenuation meter at 9 wavelengths) and SaFIre (spectral fluorescence meter), Satlantic OCR (Ocean Color Radiometer) and Hyperspectral TSRB (Tethered Spetral Radiometric Buoy), Hobi Labs Hydroscat 6, Falmouth Scientific Inc. (FSI) CTD (Conductivity Temperature Depth), and LISST (Laser in-situ Scattering and Transmissometry).

These tow profiles are only done during the summer time to study upwelling along the New Jersey coast. Below you can choose which year you would like to see images from.
