Too warm? Too cold? Too salty? Not salty enough? Scientists use the CTD sensor to search for seawater that Pollock find just right.

Like Goldilocks, Pollock are always looking for sea water that is just right. The <i>Oscar Dyson</i> has the tools for testing all sorts of abiotic factors. This is the Conductivity Temperature Depth sensor (Also known as the CTD). The CTD sends signals up to computers in the cave to explain all sorts of abiotic conditions in the water column. It can measure how salty the water is by testing how well the water conducts electricity. It can tell you how cloudy, or turbid, the water is with a turbidity sensor. It can even tell you things like the amount of oxygen dissolved in the ocean." - Greg Cook
