euphotic उदाहरण वाक्य
उदाहरण वाक्य
- However, vertical mixing also causes high losses, as phytoplankton are carried below the euphotic zone ( so their respiration exceeds primary production ).
- It extends from the surface down to a depth where light intensity falls to one percent of that at the surface, called the euphotic depth.
- As with self-shading within water-whitening coccolithophore plankton blooms, this may reduce photosynthetic productivity by altering the geometry of the euphotic zone.
- Plankton drive the " biological pump ", a process by which the ocean ecosystem transports carbon from the surface euphotic zone to the ocean's depths.
- The dysphotic zone, where light intensity is considerably less than 1 % of surface irradiance, extends from the base of the euphotic zone to about 1000 metres.
- The dysphotic zone, where light intensity is considerably less than 1 % of surface irradiance, extends from the base of the euphotic zone to about 1000 meters.
- Indeed, in their original paper, Eppley & Peterson noted that : " To relate new production to export requires that nitrification in the euphotic zone be negligible ".
- With an annual average chlorophyll a in the mixed layer of 2.2 mg m " 3 and low nutrient levels in the euphotic zone, the lake is clearly oligotrophic.
- Negative values indicate regions in which the dissolved oxygen concentration is elevated above its equilibrium saturation concentration, typically in near-surface euphotic zoneeuphotic waters by primary production and the resulting oxygen evolution.
- In open-ocean systems, biological production depends on intense nutrient recycling within the euphotic ( sunlit ) zone, with only a small fraction supported by the input of new nutrients.
