System Design and sea trial of Reciprocating Ocean Profiler based on Potential-energy-driven

Abstract

The method based on potential driven and distributed design can theoretically solve a series of bottlenecks in the current deep-sea profile observation technology (such as difficult to achieve large depth, high speed, long range, carrying large sensors, etc.). Based on this method, a set of deep-sea profile observation prototype with SBE37 CTD is designed and developed, and the key technology of designing the prototype is introduced in detail. The prototype has been tested in the South China Sea for 5 days, and 11 CTD data of reciprocating profiles have been obtained. The length of each section is 1000 meters, and the reciprocating velocity of the platform reaches 0.3 m/s. The results of the sea test fully validate the feasibility of the potential drive and distributed design method, so that the mooring reciprocating profile observation system can be continuously observed without the power provided by batteries, which fundamentally solves a series of bottlenecks caused by the previous integrated design and battery power supply. From the technical point of view, this distributed potential energy driven reciprocating profile observation system can meet the higher requirements of ocean observation, such as full depth, high speed, long range, real-time data transmission.
