CTD

A CTD is so named as it measures Conductivity, Temperature and Depth. These parameters can then be used to calculate salinity and density. There are a variety of CTD’s within the OOI program with unique capabilities. Some CTD’s are configured with inductive communication (CTDMO), a bottom pump to control flow through the instrument (CTDBP), or the ability to be mounted to a profiler (CTDPF), glider (CTDGV), or AUV (CTDAV).
