Ocean cluster observation method

Abstract

The invention discloses an ocean cluster observation method which comprises the following steps: a, in a set observation area, observation positions are determined, and each observation position comprises a plurality of observation nodes; b, arranging a plurality of observation systems by the test mother ship, and arranging the observation systems at the initial observation positions; c, a plurality of observation systems are controlled to move to the corresponding observation nodes respectively, and then the observation systems conduct synchronous vertical diving observation; in the diving process of the observation system, dynamic positioning is carried out through the full-rotation middle vector propeller; after observation is completed, the observation system floats obliquely; after the observation system floats to the water surface, the observation system is controlled to move to a second observation position; therefore, cluster observation of the observation area is completed. According to the invention, the problem of rapid, cross-regional and time-space synchronous refined observation of the small-and-medium-scale process in the ocean can be solved, multi-body cluster networking can be carried out, and small-and-medium-scale cluster observation in the ocean can be realized.

Description

technical field [0001] The invention relates to the field of ocean observation, in particular to an ocean cluster observation method. Background technique [0002] There are many dynamic processes at different scales in the ocean, ranging from the global-scale oceanic heat belt, the basin-scale western boundary current, to mesoscale eddies and small-scale turbulent mixing. Complex process coupling and energy cascades occur between these dynamic processes at different scales, which directly determine the energy and material transport in the ocean. Therefore, rapid cluster observations of processes at different scales in the marine environment, especially small and medium scales, are crucial. Mesoscale processes in the ocean are typical fast and dynamic dynamical processes with a spatial scale smaller than a kilometer and a time scale within a day (or even a second). Its life cycle is very short, the spatial scale is small, and the evolution process is random. The existing o...

Problems solved by technology

Among them, the cost of ship-borne navigation observation is huge, and it is impossible to realize multi-ship group synchronous observation in a certain sea area, and then it is impossible to realize small and medium-scale space synchronous observation; submarine buoy observation can only realize vertical single-point long-term observation, and its level The spatial resolution is insufficient, so it cannot meet the characteristics of multi-scale and cross-region spatial synchronization observation; Argo buoy is a relatively mature ocean observation system, but it can only realize profile movement, does not have the ability to actively move laterally, and has poor maneuverability; underwater navigation The underwater vehicle can be used for medium and small-scale ocean observations, but the existing underwater vehicles have poor maneuverability, flexibility, dynamic positioning, etc., which are specifically reflected in poor autonomous space movement capabilities, low horizontal measurement accuracy, and low autonomous positioning accuracy in strong current sea areas. (For example, it is easy to be washed away by ocean currents, out of the original measurement position, and difficult to return to the original position by self-adjustment), etc., thus affecting the observation accuracy and the cluster synchronization observation effect in a certain area
