Deep sea layered air-tight water sampling system

Abstract

The invention discloses a deep-sea stratified airtight water sampling system. The system comprises a waterborne control system and an underwater water sampling system. The waterborne control system comprises a computer terminal and a deck unit connected with the computer terminal, an the underwater water sampling system comprises a frame, a release device, an underwater control unit, an annular water sampling bottle array, a conductivity-temperature-depth sensor unit, an underwater power supply and a data interface unit. The deep-sea stratified airtight water sampling system can help quickly take sea water samples, remains all gas components in the samples, and supply the sea water samples which can really reflect composition information of in-situ gas for the deep-sea gas research. The deep-sea stratified airtight water sampling system provides important indexes for pursuing the process and the mechanism of marine physical change, marine chemical change and marine biological change, and for the search of resources such as volcanogenic massive sulfide ore deposits, gas hydrates and the like.

Description

A Deep Sea Layered Airtight Water Harvesting System technical field The invention relates to a deep sea water collection system, in particular to a system for collecting water samples of different water layers in the deep sea and realizing airtight sampling. Background technique The study of deep sea gas has important scientific and practical significance. On the one hand, deep-sea gases play a key role in the gas biogeochemical cycle that affects global climate change, and its research can provide insights into the processes and mechanisms of ocean physical, chemical, and biological changes and predict changes in the global climate environment. Valuable information. On the other hand, the abnormal distribution of deep-sea gas is also an important indicator for exploring resources such as hydrothermal sulfide and natural gas hydrate. Therefore, collecting airtight seawater samples in the vertical section of the entire ocean can provide reliable and continuous raw data fo...

Problems solved by technology

When the water sampler collects water samples in the deep sea and recovers them from a high-pressure and low-temperature environment of several thousand meters to a normal temperature and pressure environment, the solubility of gases in seawater will change due to changes in temperature and pressure, and some gases may be due to Escape loss due to supersaturation, so that the analytical data cannot truly reflect the composition information of the in-situ gas
