Marine sediment oceanography Britannica

2 天前  Marine sediment, any deposit of insoluble material, primarily rock and soil particles, transported from land areas to the ocean by wind, ice, and rivers, as well as the remains of marine organisms, products of submarine volcanism, chemical precipitates from seawater, and materials from outer space (e.g., meteorites) that accumulate on the seafloor.

Ocean 540: Marine Sedimentation

2004-5-21  Oceanography 540--Marine Geological Processes--Winter Quarter 2001 Marine Sedimentation. Marine sediments are the products of a limited number of physical, biological, and chemical processes. The nature of the resultant sediments is determined by the relative rates of input of material supplied by these processes.

The Mechanics of Marine Sediment Gravity Flows

Most marine sediment gravity flows are supercritical and thus controlled by sediment supply to the water column. Therefore, the genesis of the flows is the key to their understanding and prediction. Virtually every subaqueous failure produces a turbidity current, but they engage only a small percentage of the initially failed material.

Marine sediment cores have been one of the most important sources of information about the long-term geologic record of LRT dust deposition. Records of eolian particle input to the deep sea can be found in most parts of the world's oceans. Marine sediments have a number of distinct advantages over other geologic records of dust input.

Tectonic control of sedimentation SpringerLink

Sedimentation is influenced by three extrinsic variables: tectonics, climate, and sea level, with the latter two potentially dependent upon each other and upon tectonics. In addition, sedimentation is affected by processes inherent to the depositional system, which act independently of the extrinsic variables.
