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...

eventually be a slide show...)
