Marine waters are those of the ocean, another term for which is euhaline seas. The salinity of euhaline seas is 30 to 35. Brackish seas or waters have salinity in the range of 0.5 to 29 and metahaline seas from 36 to 40. These waters are all regarded as thalassic because their salinity is derived from the ocean and defined as homoiohaline if salinity does not vary much over time (essentially constant). Classification of thalassic waters by salinity and relation to the sea is provided by Venice system (1959) modified by Por (1972). Waters of the Baltic sea independently of salinity are thalassic or homoiohaline.

(1) A process that brings together multiple users of the ocean—includingenergy, industry, government, conservation, and recreation—to make informed and coordinated decisions about how to use marine resources sustainably based on a spatial framework (maps). Marine protected areas and fisheries reserves are examples of tools for marine spatial planning (2) In its broadest sense is about analysing and allocating parts of three-dimensional marine spaces to specific users, to achieve ecological, economic, and social objectives that are usually specified through the political process. MSP is place- or area- based and can provide a practical approach to long-term ecosystem-based management. MSP should be comprehensive, adaptive and participatory, and resolve conflicts among multiple uses and ecosystem (UNESCO MSP Workshop 2006). MSP is about planning when and where human activities take place at sea. It is a transparent and comprehensive process based on stakeholder involvement. Its aim is to draw up plans which identify the most efficient and sustainable current and future use of maritime space. The intended result of MSP is a more coordinated and sustainable approach to how our oceans are used – ensuring that the seas marine resources and services are utilized, but within clear environmental limits to ensure marine ecosystems remain healthy and biodiversity is conserved. MSP is complementary to Integrated coastal Management seeIntegrated Coastal zone management (ICZM)(http://ec.europa.eu/maritimeaffairs/policy/maritime_spatial_planning/index_en.htm) (3) Is a tool for improved decision-making. It provides a framework for arbitrating between competing human activities and managing their impact on the marine environment. Its objective is to balance sectoral interests and achieve sustainable use of marine resources in line with the EU Sustainable Development Strategy (http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=CELEX:DKEY=483715:EN:NOT)

An area of low-lying wetland in which the level of water is generally shallow and often fluctuating. The water may be either standing or slow-moving.

Community comprising megafauna, benthic organisms that can beseen by the naked eye or be detected in underwater photographs.

Animals that can be seen by the naked eye; also defined as animals larger than100 pounds (45 kg) in weight.

Is a lower flow regime type of sedimentary bedform. The term "megaripple" has largely been replaced with "dune" in the marine geology literature. 

Animals in the size range 0.063–0.5 mm.

Depths between 200 and 1,000 m.

Awater body that has moderate levels of nutrients and algae.

A population that exists in a connected complex of spatially discrete habitatfragments.
