Drawing on-line measuring system in deep sea

Abstract

An on-line measuring system of pull type in deep sea is prepared as using transducer detection subsystem to detect deep sea data and transmitting detected data to hyper baric chamber measuring and controlling subsystem under water as well as transmitting said data to deck control subsystem after it is stored in hyper baric chamber measuring and controlling subsystem underwater, storing and processing as well as displaying said data by deck control subsystem.

Description

【Technical field】 [0001] The invention relates to the detection of deep-sea marine environment parameters, in particular to the detection of deep-sea marine environment parameters in hydrothermal mineralization areas. 【Background technique】 [0002] In recent years, marine scientists have realized that the evolution of mid-ocean ridge hydrothermal activity is a dynamic environmental system, and its chemical, physical and biological processes have strong changes in time and space scales, trying to reconstruct it with traditional sampling-measurement methods The authenticity of the original environment of fluid chemistry has been questioned. The temperature-pressure-composition conditions in seawater are significantly different from the normal temperature and pressure conditions of marine scientific research ships and land laboratories, although the process of "sampling-(on-board or on-shore) laboratory analysis" has been targeted to varying degrees.

The temperature-pressure-composition conditions in seawater are significantly different from the normal temperature and pressure conditions of marine scientific research ships and land laboratories, although the process of "sampling-(on-board or on-shore) laboratory analysis" has been targeted to varying degrees. Different research objects have taken some fidelity measures, but it has to be admitted that the understanding obtained through these traditional methods and means still cannot fully reflect the true appearance of the ocean / seabed material world

The traditional working method of collecting samples at different positions and depths in the ocean at sea, and performing various chemical analyzes on the samples in the on-board laboratory or back to the shore-based laboratory has the following disadvantages: it consumes a lot of manpower and material resources, and prolongs the time spent on the ship at sea. The operating time is low, so the efficiency is low and the cost is high; the capacity of the seawater collector is limited, and the representativeness of the obtained biological and microbial samples is not good, which is not conducive to a comprehensive understanding of the marine ecological environment of the detected sea area; the collected samples are due to temperature, pressure, light Changes in conditions such as gas phase will cause the loss of dissolved components in the gas phase, changes in the valence state of variable ions, changes in the structural relationship between compounds of different components or between monomers of compounds of the same component, and the decomposition of organic components. Therefore, it is difficult for the analysis data to accurately reflect the seawater. original composition and condition
