Autonomous Ocean Sampling Network

Researchers gathered at MBARI for a month-long experiment to study upwelling features in the Monterey Bay during the summer of 2003. The unprecedented in situ observational capability is depicted in these plots of autonomous vehicle paths during the experiment. In the left panel, the autonomous vehicle tracks are shown over the August 15, 2003 sea-surface temperature , which indicates upwelling. In the right panel, aircraft, high frequency radar currents, drifter, moorings, ships CTD, and towfish tracks are shown over the August 23, 2003 sea-surface temperature, which show a relaxation of the upwelling.Panels below show, from left to right, description of the planned data flow for the operational system, the actual deployment schedule for the in situ observational systems, and the resulting observational capability described in terms of vertical profiles per day.
