Glossary (eng)

In marine mapping, a term used to describe the frequency of sound, equal to 1,000 cycles per second (Hertz). 100 kHz is equal to 100,000 Hz, etc.

A system of knowledge (systematized existing information and collected data) that underlie MSP. This system brings together marine data from different sources with the aim of: (1) helping industry, public authorities and researchers find the data and make more effective use of them to develop new products and services: (2) Improving our understanding of how the seas behave. (see more on Marine Knowledge 2020 athttp://ec.europa.eu/maritimeaffairs/policy/maritime_spatial_planning/index_en.htm)

(1) A shallow marine (sometimes brackish to hypersaline) coastal water body, receiving little if any fluvial input, separated from the sea by a restricted inlet usually having a sill. (2) Lagoons are expansions of shallow coastal salt water, of varying salinity and water volume, wholly or partially separated from the sea by sand banks or shingle, or, less frequently, by rocks. Salinity may vary from brackish water to hypersalinity depending on rainfall, evaporation and on the addition of fresh seawater from storms, temporary flooding of the sea in winter or tidal exchange. With or without vegetation from genera Ruppia sp., Potamogeton sp., Zoster asp. or Chara sp. Flads and gloes, considered a Baltic variety of lagoons, are small, usually shallow, more or less delimited water bodies still connected to the sea or have been cut off from the sea very recently by land upheaval. Characterized by well-developed reedbeds and luxuriant submerged vegetation and having several morphological and botanical development stages in the process whereby sea becomes land. Salt basins and salt ponds may also be considered as lagoons, providing they had their origin on a transformed natural old lagoon or on a saltmarsh, and are characterized by a minor impact from exploitation.

(1) The distinct association of landforms, esp. as modified by geologic forces, that can be seen in a single view, e.g. glacial landscape (Geology of Glossary). (2) Basic digit of physio-graphic division (zoning)-genetically united area with homotypic terrain, geologic structure, climate, common type of surface and subterranean waters,regular soils combinations, plants and animals communities; (3) (Russian Federation GOST 17.8.1.01-86) A territorial system, consisting of interacting natural or natural and anthropogenic components and complexes of lower taxonomical rank.

Expression of the morphology and dynamics of the coasts of active and passive climate and determination of the coasts using biological factors.

Sediment embankment deposited along the sides of rivers or submarine canyons.

Sedimentary rock comprised of more than 50% calcium carbonate.

Muddy clay deposited during the Baltic Sea phase Litorina. Is typically olive gray clay with thin laminae.

Is brackish water phase of the Baltic Sea before the current sea stage around 8500-4500 calibrated years ago.

Living in the littoral zone.
