Flow Mow CTD Instrumentation

A package of instruments that makes measurements of conductivity, temperature, and pressure is commonly referred to as a "CTD" by oceanographers. This is a bit confusing; why isn't it called a "CTP?" The quick answer is that the measurements are used to calculate three parameters that usefully characterize seawater: salinity (from conductivity), temperature, and depth (from pressure). The quick response is that you really ought to call it a "STD," but unfortunately that acronym is already taken. Alternatively, since the temperature is really calculated from a resistivity reading, we should call it a "CReP." Pending further consideration, we'll keep calling it a CTD...
