Soil Sampling - an overview | ScienceDirect Topics

Peter Aird, in Deepwater Drilling, 2019. Soil Sampling. Shallow soil sampling may be acquired to obtain and measure geotechnical properties below the seabed. 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).
