SBE 16plus CTD
CTD stands for conductivity, temperature, and depth, and refers to a package of electronic instruments that measure these properties. The use of Sea-Bird 16plus V2 RS232 C.T.D. allow us to measure the phisycal parameters of the water with a great accuracy.
A CTD device’s primary function is to detect how the conductivity and temperature of the water column changes relative to depth. Conductivity is a measure of how well a solution conducts electricity. Conductivity is directly related to salinity, which is the concentration of salt and other inorganic compounds in seawater. Salinity is one of the most basic measurements used by ocean scientists. When combined with temperature data, salinity measurements can be used to determine seawater density which is a primary driving force for major ocean currents.
The knowledge we obtaine from CTD device gives us the ability to a better understanding of factors such as species distribution and abundance in particular areas of the water column.
