Continuous real time scanning of the upper ocean water column

The Cabled Array portion of the National Science Foundation funded Ocean Observatories Initiative is a large scale, high bandwidth and high power subsea science network developed by the University of Washington Applied Physics Laboratory. Part of that system is a set of moorings and winched profilers which continuously scan the upper 200m of the ocean at their deployment sites. The profilers have been in operation since July 2014 and have accumulated a significant performance record. The general design approach, performance results and lessons learned are described.
