Abstract

PROFILING SYSTEMS ON CABLED OBSERVATORIES: EXPERIENCES IN THE NORTHEAST PACIFIC

Ocean Networks Canada has two water column profiling systems. One is located in a quiescent fjord on the VENUS coastal observatory, the other offshore over the continental slope on the NEPTUNE regional observatory. The two markedly different environs are approached with two equally different profiling solutions. The inshore system incorporates an instrument profiler that is lowered and raised from a large surface float, while the offshore system incorporates a winch on the seafloor that allows a float to rise to the sea surface. We present the ocean engineering rationalisation for the two designs and address the limitations of each. Data collected over the summer of 2012 and the Winter of 2013 are presented to illustrate the value of high temporal-resolution continuous-water column measurements. Observations from the floats include salinity, temperature, oxygen, fluorescence, pCO2, radiometry, nitrate, and pressure.
