DEF

The depth in the oceans below which the rate of supply of calcium carbonate ... equals the rate of solvation, such that no calcium carbonate is preserved.

OBS

carbonate compensation depth: term used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Géochimie
  • Océanographie
DEF

Niveau (entre 3 500 et 5 000 mètres) dans l'océan au-dessous duquel on ne trouve plus de carbonates dans les dépots marins, ceux-ci étant dissous.

CONT

[Le niveau] où la dissolution est totale est le niveau de compensation des carbonates (NCC ou CCD, Calcite Compensation Depth). La CCD située vers 5 000 m dans l'Atlantique est moins profonde dans le Pacifique [...]

CONT

Le niveau de dissolution totale de la calcite ou niveau de compensation de la calcite [...] est la profondeur en dessous de laquelle le taux de dissolution de la calcite excède le taux d'apport.

DEF

Depth at which the rate of photosynthesis equals the rate of respiration.

CONT

The compensation depth is a layer of transition from the trophogenic zone to the tropholytic zone where carbon dioxide production is greater than oxygen production.

French

Domaine(s)
  • Biophysique
  • Océanographie
  • Cultures (Agriculture)
DEF

Profondeur à laquelle l'atténuation de la lumière solaire due à l'absorption est telle que les processus de la photosynthèse parviennent à compenser les pertes métaboliques dues à la respiration.

CONT

La croissance des végétaux est donc possible au-dessus d'une ligne appelée «niveau de compensation» c'est-à-dire lorsque le bilan photosynthèse/respiration est positif [...]

English

Subject field(s)
  • Equipment and Facilities (Recreation)
  • Swimming
DEF

A line from below the pool surface to the body of a skimmer designed to prevent air being drawn into the filter when the water level drops below the skimmer inlet.

DEF

A connection with an automatic valve from the pool to the skimmer tank body, sufficiently below the weir and of adequate size to satisfy pump demand and prevent airlock when pool water level drops below weir.

OBS

The valve opens when the water level drops, allowing pool water to maintain flow, and remains closed during normal skimming.
