Geological Theory - an overview | ScienceDirect Topics

People eventually accepted Hutton's cyclic theory, even though they could make little sense of the physical basis he envisaged. But acceptance took time, and geological theory was racked with controversy until well into the 1820s. The Professor of Natural History, Robert Jameson (1774–1854), gained control of geology teaching at Edinburgh ...

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).
