A group of geographically or geologically associated islands.
An area of water bordered by land on three sides.
Single birth offspring quantity. The proportion or number of offspring produced from a single pregnancy (mammals) or ovulation (fish) or nesting (birds).
Aragonite structures produced by living organisms, found in shallow, marine waters with little nutrients in the water.
A plane angle unit which is equal to 1/360 of a full rotation or 1.7453310^[-2] rad.
Expressions of the estuarine biome occur at wide lower courses of a rivers where they flow into a sea. Estuaries experience tidal flows and their water is a changing mixture of fresh and salt.
consumes for energetic or other nutritional needs
A facility in which fish are raised commercially in tanks or enclosures, usually for food.
A description of the geographic distribution, or range, of the taxon. Includes descriptions of global, regional, or political aspects of range and whether the taxon is native or introduced in portions of the range and endemicity.
The natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.

Kilograms. A mass unit which is equal to the mass of the International Prototype Kilogram kept by the BIPM at Svres, France.
The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.
The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.
Meters. A length unit which is equal to the length of the path traveled by light in vacuum during a time interval of 1/299 792 458 of a second.
A habitat that is in or on a sea or ocean containing high concentrations of dissolved salts and other total dissolved solids (typically >35 grams dissolved salts per litre).
Mediterranean sea biome
The mediterranean sea biome comprises mostly enclosed seas that have limited exchange of deep water with outer oceans and where the water circulation is dominated by salinity and temperature differences rather than winds.
Milliliters per liter. A volume per unit volume unit which is equal to one millionth of a liter of solute in one liter of solution.
A mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island. Typically formed from volcanoes that rise abruptly and are usually found rising from a seafloor of 1,000 - 4,000 meters depth. Independent features that rise to at least 1,000 meters above the seafloor.
The exit or point of discharge of a stream into another stream, lake or sea.
The region occupied by any more or less continuous, directed movement of ocean water that flows in one of the Earth's oceans. Ocean Currents are rivers of hot or cold water within the ocean. The currents are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon. The depth contours, the shoreline and other movements influence the direction and strength of the movements of water that forms a given current.
An open ocean region.
A dimensionless ratio unit which denotes numbers as fractions of 100.
Practical Salinity Units. The conductivity ratio of a sea water sample to a standard KCl solution. Used to represent salinity.
The depth of seawater at a location where this organism has been observed or collected.
Seawater dissolved O2
Dissolved oxygen concentration in seawater at a location where this organism has been observed or collected.
Dissolved nitrate concentration in seawater at a location where this organism has been observed or collected.
Seawater O2 saturation
The percent oxygen saturation in seawater at a location where this organism has been observed or collected.
Dissolved phosphate concentration in seawater at a location where this organism has been observed or collected.
Dissolved salt concentration in seawater at a location where this organism has been observed or collected.
Dissolved silicate concentration in seawater at a location where this organism has been observed or collected.
Temperature of seawater at a location where this organism has been observed or collected.
That part of the land in immediate contact with a body of water including the area between high and low water lines.
A layer within a water body where the temperature changes rapidly with depth.
A physical quality inhering in a bearer that has mass near a gravitational body.
A unit of molarity which is equal to one millionth of a molar or 10^[-6] mol/L
