Abstract

The invention discloses a penetration probe-based deep sea multi-element comprehensive observation system, which comprises an upper computer and a data recovery cabin, wherein the upper end and the lower end of the data recovery cabin are connected with a probe rod through a hydraulic separation releaser and a launching device respectively; a small-sized pile driver is arranged in the launching device; the launching device is provided with an underwater search light, an underwater camera and an underwater acoustic communication transceiver; the top of the data recovery cabin is provided with a floating body; a central controller is included in the data recovery cabin; the outer side face of the data recovery cabin is provided with an underwater acoustic transducer; and the outer surface of the probe rod is provided with more than 10 annular electrodes and more than 2 pore water pressure sensors which are connected with the central controller. The system has a simple structure, is reliable in work and accurate in control, can carry various sensors and adapt to a deep sea high pressure environment, and can synchronously and automatically observe and record states and changes of sea water and sediments within a 10m depth range close to a sea water-sediment interface with over 2,000m water depth, including the state of sediments of 6-7m below a sea bottom surface, the condition ofsea water of a bottom layer of 3-4m above the sea bottom surface and the dynamic change in position of the sea bottom surface.

Description

technical field [0001] The invention relates to a deep-sea multi-element comprehensive observation system based on a penetrating probe, which is used for observing the dynamic change process of the interaction zone between seawater and sediment in the deep sea, and belongs to the technical field of ocean observation. Background technique [0002] In-situ long-term, continuous, and fixed-point observation of modern processes on the deep seabed is an important means for marine science to advance to the deep sea, especially the observation of the dynamic change process of the deep seawater-sediment interaction zone, which is important for revealing the occurrence of modern sediments under the action of deep sea dynamics. It plays an important role in understanding the dynamic response process and in-depth understanding of the evolution history of deep-sea sediment filling. At present, the methods for in-situ long-term observation of the deep seabed in the world, one is a bottom...
