[0002] The shallow water surface refers to the surface area of the ocean or lake with relatively shallow water depth, usually referring to the area with a water depth ranging from several meters to dozens of meters. This area is of great significance to marine organisms, marine ecosystems and marine resources, because it is usually the habitat of shallow sea organisms and is greatly affected by factors such as sunlight, tides and waves.

[0003] Shallow water surface sediment refers to the sediment deposited at the bottom of the shallow water area of the ocean or lake. These sediments include fine sand, clay, organic matter, etc., and are usually formed by the remains of marine organisms, plant residues, particulate matter, etc. depositing in the water body. Shallow water surface sediment plays an important role in the stability and development of the marine environment and ecosystem, and is also an important habitat for seabed organisms. When studying the change law of shallow water surface sediment, it is often necessary to sample and analyze the surface sediment. Therefore, a shallow water surface sediment sampling device is needed.

When the existing shallow water surface sediment sampling device is in use, a grab sampling device is usually used for sediment sampling, which is easy to cause great damage to the sediment sequence structure, difficult to maintain the original shape, and the sampling success rate is relatively low, unable to meet people's needs.
