I'm sure that the oceans are being monitored (and not by plastic water bottes) to collect data -- there is a lot of monitoring stations that give real-time data on ocean currents -- probably not in this area, and there are a lot of computer models. I am sure that data is being collected by the ships as they trawl for debris to get real-time data -- depth and surface information. again, something I know a fair bit about. my posts keep being deleted.
