- Describes the behaviour of fish which aggregate together, including mixed species groups. fish derive many benefits from shoaling behaviour including defence against predators through better predator detection and by diluting the chance of capture, enhanc
- [1] the increase in height and decrease in length of a wave as it approaches a shoal. [2] becoming shallower.

Drift [glacial geology], английский
A general term applied to all mineral material (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by running water emanating from a glacier. drift includes unstratified material (till) that forms moraines, and stratified deposits that form outwash plains, eskers, kames, varves, and glaciofluvial sediments. the term is generally applied to pleistocene glacial deposits in areas that no longer contain glaciers. gg
Dredged channel, английский
A roughly linear, deep water area formed by a dredging operation for navigation purposes (after wells et al., 1994; dredged hole). compare - dredge-deposit shoal. sss
