Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Sediment transport is the movement of solid particles , typically due to a combination of gravity acting on the sediment, and the movement of the fluid in which the sediment is entrained.
Coastal sediment transport (a subset of sediment transport) is the interaction of coastal land forms to various complex interactions of physical processes. [1] [2] The primary agent in coastal sediment transport is wave activity (see Wind wave), followed by tides and storm surge (see Tide and Storm surge), and near shore currents (see Sea#Currents) .

RV Investigator is an Australian marine research vessel which was designed by RALion (joint venture between Robert Allan Ltd. and Alion Science and Technology).It was constructed in Singapore and is owned and managed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), through Australia's Marine National Facility, [1] with its operations funded by the Australian ...
The Van Veen grab sampler is an instrument to sample sediment in water environments. Usually it is a clamshell bucket made of stainless steel. Up to 20 cm deep samples of roughly 0.1 m 2 can be extracted with this instrument. It can be light-weight (roughly 5 kg) and low-tech. The smallest version even fits into hand luggage.
Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle, shells) along a coast parallel to the shoreline, which is dependent on the angle of incoming wave direction.
The InterContinental Resort is the largest seawater air conditioning system to date, though there are several other, larger systems being planned. [7] Honolulu Seawater Air Conditioning was a project intended to use seawater air conditioning to deliver renewable cooling to commercial and residential properties in the downtown Honolulu area.
A grab dredge. Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value.
