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.

本发明涉及海洋测量技术领域，特别涉及一种海底边界层观测装置及其布放回收方法。本发明采用了观测平台和回收装置的分体式设计，将体积庞大的浮体材料跟观测设备分离开来，避免了其对海流等关键参数的影响，大大提高了观测数据的准确性；利用连接缆绳回收海底的观测平台，可以提供足够的拉力，避免了观测平台陷入沉积物中，不能顺利脱离海底的情况；回收装置链式设计，当其上浮至水面后，更利于大型科考船的回收；其布放回收方法针对该装置的特点设置，稳妥可靠，适用于各类船舶，具有较好的推广前景。
