Soil Sampling - an overview | ScienceDirect Topics

A common method is to use gravity-based coring devices that can produce a continuous core of the upper 0-6 m (0-20 ft) below the seabed. The unit is simple and reliable and can operate well in water depths > 1000 m (3281 ft). The gravity corer cannot however function when the seabed consists of sand, gravel, or other hard soils.
