The SBE 41N CTD measures conductivity, temperature, and pressure (depth). The pump-controlled, T-C ducted flow minimizes salinity spiking caused by mismatch of temperature and conductivity measurements.
The SBE 63 is an individually calibrated, high-accuracy, optical oxygen sensor. Careful choices of materials and geometry are combined with superior electronics and calibration methodology to yield significant gains in performance.The SBE 63 is designed for use in a CTD’s pumped flow path, providing optimal correlation with CTD measurements. The elapsed time between the CTD and associated oxygen measurement is easily quantified, and corrected for, in post-processing. The plumbing’s black tubing blocks light, reducing in-situ algal growth.
The ECO-MCOMS uses demonstrated WET Labs technology to supply three optical sensors in one, providing chlorophyll a, backscattering, and CDOM, or chlorophyll a and 2 backscattering channels. MCOMS is integrated directly into the float end cap and co-located with DO and physical measurements.
The Float pH adapts Deep-Sea ISFET technology for profiling floats, providing stable pH measurements for missions up to 2000 db. Externally, it consists of a pH-sensing ion selective field effect transistor (ISFET) and a solid state Ag/AgCl reference connected to the CTD’s pumped flow path.
Additional Sensor Options
Available bolt-on sensors include the Deep SUNA (nitrate), OCR 504 (4-channel radiometer), and WET Labs C-Rover 2000 (transmissometer).
