Platforms offshore Mexico. Offshore geotechnical engineering is a sub-field of geotechnical engineering.It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea. [1]
In both marine and terrestrial environments, ferromanganese nodules are composed primarily of iron and manganese oxide concretions supported by an aluminosilicate matrix and surrounding a nucleus. [ 2 ] [ 3 ] Typically terrestrial nodules are more enriched in iron, while marine nodules tend to have higher manganese to iron ratios, depending on ...
Marine geophysics is the scientific discipline that employs methods of geophysics to study the world's ocean basins and continental margins, particularly the solid earth beneath the ocean. It shares objectives with marine geology , which uses sedimentological , paleontological , and geochemical methods.
Offshore (or marine) geotechnical engineering is concerned with foundation design for human-made structures in the sea, away from the coastline (in opposition to onshore or nearshore engineering). Oil platforms, artificial islands and submarine pipelines are examples of such structures. [16]

Pako Guyot reaches a depth of 1,350 metres (4,430 ft). [3] It has dimensions of 40 by 65 kilometres (25 mi × 40 mi) and features a summit plateau 2,056 square kilometres (794 sq mi) wide [4] at a depth of 1,500–1,650 metres (4,920–5,410 ft) [3] with a shape corresponding to an irregular rectangle-triangle.

Marine Geology is a peer-reviewed scientific journal about marine geology published by Elsevier.About its scope the journal states "We accept papers on subjects as diverse as seafloor hydrothermal systems, beach dynamics, early diagenesis, microbiological studies in sediments, palaeoclimate studies and geophysical studies of the seabed."
Iceberg drifting into shallower waters and gouging the seabed as it comes into contact with it. Drifting sea ice pressure ridges can also gouge the seabed.. Seabed gouging by ice is a process that occurs when floating ice features (typically icebergs and sea ice ridges) drift into shallower areas and their keel comes into contact with the seabed.
