Coral Bleaching

Occurs when a coral becomes stressed and expels most of its colorful algae, leaving an underlying ghostly white skeleton of calcium carbonat.

Nekton

Strongly swimming organisms found in aquatic systems.

Benthos

Botton-dwelling organisms.

Coastal Zone

Warm, nutrient-rich, shallow part of the ocean that extends from the high-tide mark on land to the edge of a shelflike extension of continental land masses known as the continental shelf.

Coastal Wetland

Land along a coastline, extending inland from an estuary, that is covered with salt water all or part of the year. Examples are marshes, bays, lagoons, tidal flats, and mangrove swamps.

Estuaries

The lower end of a river, where it meets ocean. Saltwater and freshwater mix here. Estuaries are known to be very productive.

Intertidal Zone

The area of shore between the high-tide and low-tide lines.

Barrier Islands

Long, thin, low offshore islands of sediment that generally run parallel to the shore along some coasts.

Euphotic Zone

Upper layer of a body of water through which sunlight can penetrate and support photosynthesis.

Abyssal Zone

The portion of the ocean floor where light does not penetrate and where temperatures are cold and pressures intense.

Marine Snow

The organic debris (plankton, dead organisms, fecal material, etc.) that "rains" into the dark area of the oceanic province from the lighted region above; the primary food of most organisms that live in the ocean's depths.

Limnetic Zone

In a lake, the well-lit, open surface waters farther from shore.

Profundal Zone

Deepest, coldest area of a large lake with little light and limited biodiversity.

Benthic Zone

Bottom of an aquatic ecosystem; consists of sand and sediment and supports its own community of organisms.

Oligotrophic

A condition of a lake or other body of water characterized by low nutrients, low productivity, and high oxygen levels in the water column.

Eutrophic

A condition in a lake or other body of water that is characterized by lush phytoplanktonic growth followed by high amounts of decay in the bottom resulting in depletion of oxygen in the water column.

Watershed

Land area that delivers water, sediment, and dissolved substances via small streams to a major stream (river).

Swamp

A wetland ecosystem in which shrubs and trees grow.

Marsh

A treeless wetland ecosystem where plants such as grasses grow.

Open Sea

The sharp increase in water depth at the edge of the continental shelf separates the coastal zone from the vast volume of the ocean.
