Sanasto (englanti)

(1) The act or process of forming or accumulating sediment in layers, including such processes as the separation of rock particles from the material from which the sediment is derived, the transportation of these particles to the site of deposition, the actual deposition or settling of the particles, the chemical and other (early diagenetic) changes occurring in the sediment, and the ultimate consolidation of the sediment into solid rock. SeeDeposition (2) Less broadly, the process of deposition of sediment. (3) Strictly, the act or process of depositing sediment by mechanical means from a state of suspension in air or water or by ice and under the influence of gravity. (4) The accumulation of deposits of colluvium and alluvium derived from accelerated erosion of the soil. (5)silting up.

(also fouling species, attached species, sedentary species, sedentaria) Sessility is a characteristic of invertebrates and primitive Chordata (Thunicata) such that they are not able to move about. Sessile animals are usually permanently attached to a solid substrate(see Periphyton). Sessile animals typically have a motile (free-living) phase in their development or resting phase (vegetative buds). Many sessile animals, including bryozoans, sponges, corals and hydra, are capable of asexual reproduction in situ by the process of budding.

A process that creates a new organism by combining the genetic material of two organisms; unification ofhaploid gametes produce a diploid organisms.

A terrace. See also Continental shelf.

(also shelf break, shelf drop-off) Marked by a seaward increase in seabed slope that occurs at the seaward limit of the continental shelf and the upper limit of the continental slope.

Shallow body of water located on a continental shelf.

Offshore hazard to surface navigation that is composed of unconsolidated material.

A non-systematic definition of birds associated (by distribution) with coastal biotopes.

A side looking sonar that is used to image the topography of the seafloor, and to detect and locate objects underwater. It collects only acoustic backscatter data.

Sediments or sedimentary rocks that are almost exclusively silica bearing, either as forms of quartz or other silicate minerals.
