The deep ocean is a rich reservoir of unique organisms with great potential for
bioprospecting, ecosystem services, and the discovery of novel materials. These organisms …

Research on deep seawater is of great importance to marine chemistry, biology, and climate
science studies. Sample analysis is the fundamental and most effective method for deep …

The full ocean depth environment is characterized by high pressure, low temperature, and
high corrosiveness, making it difficult for the current deep-sea sampling equipment to obtain …

Warming poses a significant threat to the utility of deep-sea samples. This study developed
an active temperature-preserving deep-sea water sampler to use at full ocean depths. The …

In Chap. 1, the point was made that the greatest pressure in the oceans, about 110 MPa, is
not particularly challenging in engineering terms. It is at the high end of the pressure range …

An airtight sampler with the function of holding pressure and coring was designed. First,
using the sediment sampling test platform, taking high sampling rate as the goal and the …

Aiming at the requirement of the full-ocean-depth (operating water depth 11000 m) manned
submersible to carry out the gas-tight sampling operation of the abyss seabed sediment, a …

The ice-seal holding-pressure technology has attracted more and more attention for it does
not have the disadvantages of traditional mechanical seals, therefore, its applications are …

The target strata of sandstone-type uranium deposits are usually located in the fragile and
loose strata, which makes it difficult to obtain core samples; consequently, a novel ice coring …
