System Description

Sea Surface Temperature
Surface temperature is monitored in two different ways. In one case, the temperature is measured directly from the sea water intake (see left and middle photos below) just after it enters the vessel. Thus this value measures water at a depth of approximately 2 meters below the surface. In the second case, the temperature of the hull near the water line is measured with a temperature sensor pressed against the port side of the hull (see left and right photos below).

Bottom (lower) and port side (upper) of hull showing route sea water traverses to car deck (out of the picture at the top).	Temperature sensor reading value from sea water intake shortly after water enters vessel.	Temperature sensor reading value from the side of the hull - this presumes the hull temperature quickly equilibrates to the outside sea water temperature.
