A pressure-retaining sampling device for deep-sea sediments

摘要

In recent years, in order to obtain the history of the ocean and promote the development of research about life science, people have been studying many deep-sea sediments. Obtaining subsurface samples closest to the original state of the ocean is a prerequisite for sediment research, so it's important for us to obtain the sediment sample. The difficulties and priorities of sampling design is to achieve the sampling process and the pressure-retaining of samples.
