Description

Technical Field

[0001] The present invention relates to the technical field of submarine cold springs, and in particular to an in-situ intelligent observation station for submarine cold springs. Background Art

[0002] Submarine cold seeps are a unique geological phenomenon in the deep-sea environment. They are usually closely related to submarine oil and gas, natural gas hydrates, and deep-sea life processes. In recent years, with the continuous deepening of marine resource exploration and development, the study of submarine cold seeps has also received increasing attention. Specifically, cold seeps are a geological process in which submarine methane hydrate decomposes to form gas and infiltrates and overflows into the high-pressure and low-temperature seabed. They are generally distributed at a depth of more than 1,000 meters. The formation and evolution of cold seeps are closely related to the formation and distribution of methane hydrate, deep-sea ecosystems, and environmental-related evolution. Among the past technical difficulties, the relevant scientific research on submarine cold seeps involves multiple fields such as earth sciences, energy and environment, and life sciences. Therefore, the research on cold seeps, marine methane hydrate resources, and cold seep environmental ecosystems is of great significance.

[0003] However, the current research on cold springs is mostly carried out through acoustic, optical, ROV, towed geochemical and other methods, with the focus mainly on the discovery of cold springs and the measurement of their distribution range. However, due to the unique periodic activity of submarine cold springs and their eruption locations that change over time, it is difficult to obtain long-term cold spring observation data through traditional single marine aerial survey methods, making the spatial and temporal changes of cold springs still in an uncertain state. At the same time, since cold springs are an important part of the deep-sea ecosystem, their uniqueness lies in the chemical substances released during activity, such as methane and hydrogen sulfide, which can support rich biological communities and form complex and delicate ecosystems. If we only rely on in-situ observation methods of a single parameter, there are great limitations and it is impossible to fully reflect the overall state of the system.

[0004] Therefore, how to establish a technical means to monitor submarine cold springs in a long-term, real-time and multi-parameter manner is a problem that people in this field need to solve. Summary of the invention

[0005] The purpose of the present invention is to provide an in-situ intelligent observation station for submarine cold springs, so as to establish a technical means capable of long-term, real-time and multi-parameter monitoring of submarine cold springs.

At the same time, the method of intelligent learning and comprehensive discrimination can be introduced to establish an algorithm for automatic discrimination of cold spring activities, and an automatic triggering sample collection mechanism can be established according to the algorithm results, so as to achieve the purpose of intelligent in-situ long-term observation, multi-mode operation management and execution control of submarine cold spring activities. Finally, the in-situ sample filtration collection can be automatically triggered according to the intelligent algorithm structure to collect samples of sedimentary fluids and seawater in the submarine boundary layer, and the collected samples can be used to carry out more targeted research on the dynamics of cold spring eruption process and environmental ecology. Exemplarily, in this embodiment, the cold spring intelligent observation station can only use the long-period in-situ suspension filtration device 62 to design a sample number of up to 360, and the in-situ water sample collection device can design a sample number of up to 100.
