Abstract

The invention relates to the technical field of ocean survey, and especially relates to a seabed boundary layer observation device and a laying and recovering method thereof. The split design of an observation platform and a recovery device is adopted, and a floating body material with a huge size is separated from observation equipment, so that the influence of the floating body material on key parameters such as ocean current is avoided, and the accuracy of observation data is greatly improved; the observation platform on the seabed is recovered by using a connecting cable, so enough tensioncan be provided, and the situation that the observation platform sinks into sediments and cannot be smoothly separated from the seabed is avoided; due to the chained design of the recovery device, after the recovery device floats up to the water surface, recycling of a large scientific investigation ship is better facilitated; and the laying and recovering method is set according to the characteristics of the device, is stable and reliable, is suitable for various ships, and has a good popularization prospect.

Description

technical field [0001] The invention relates to the technical field of oceanographic measurement, in particular to a seabed boundary layer observation device and a deployment and recovery method thereof. Background technique [0002] The seabed boundary layer includes the thickness of the water layer from the bottom of the bed to the water body significantly affected by it, which has an important impact on the dynamic process of the seabed, especially the sediment transport and the transport of chemical substances near the seabed. Therefore, it is urgent to study the observation of the bottom boundary layer technology. [0003] The traditional submarine observation seabed base mostly adopts a self-floating design, and after the observation is completed, the load is discarded and rises to the water surface by its own buoyancy. However, the addition of a large number of floating body materials on the seabed base leads to an increase in its volume, which affects the underwater...
