System and method for bio-optical environmental reconnaissance

摘要

System for collecting ocean data includes a trawl-resistant bottom mooring having a base unit and profiler on board. Method for collecting ocean data includes steps for receiving and executing a configuration file in the base unit and the profiler, collecting data, transmitting the data to a receiving station, and transferring to and archiving the data in the base unit.

主权项

1. A bottom mooring for enabling ocean measurement data comprising:
a base unit having a low profile cross-section, a low center of gravity, and a smooth upper surface with no edges or protruding structures; a profiler including a plurality of optical sensors, an antenna and communications equipment transmitting the ocean measurement data collected by the sensors to a receiving station through the antenna; a cable attaching the profiler to the base unit; a controller and winch controlling ascent of the profiler from the base unit to a water surface, the controller controlling timing and sampling frequency of the ocean measurement data, and the controller and winch controlling descent of the profiler such that the profiler is stowed completely in the base unit with no portion of the profiler protruding into the water column when the profiler is completely descended; an enclosure system surrounding the optical sensors on the profiler protecting the bio-optical sensors from bio-fouling; at least one profiler battery mounted in the profiler and powering the antenna, the CTD sensor, and the optical sensors; an acoustic Doppler current profiler (ADCP) in electronic communications with the base unit; and a base unit battery set mounted in the base unit powering an on-board computer and the winch, the base unit battery set inductively charging the at least one profiler battery.
