Summary
| Description |
English: The Cromwell Current stirs up the ocean on the west (leeward) side of the Galapagos, and brings cool, nutrient-rich water up from the ocean depths (Upwelling). The nutrients nourish phytoplankton, which form the base of the ocean’s food web. Many fish, birds, and marine mammals depend on the phytoplankton. The bottom image shows sea surface temperature, cool up welling waters are coloured purple. Thriving phytoplankton populations are indicated by high chlorophyll concentrations (top image), coloured green and yellow. Images acquired on March 2, 2009.
Français : Le courant de Cromwell, actif du côté ouest (sous le vent) des Galapagos, apporte de l’eau fraîche et riche en nutriments des profondeurs de l’océan (upwelling). Ces nutriments nourrissent le phytoplancton, qui constitue la base du réseau trophique de l'océan. De nombreux poissons, oiseaux et mammifères marins dépendent du phytoplancton. L'image du bas montre la température de la surface de la mer, les eaux froides en violet. Les populations de phytoplancton en plein essor sont indiquées par des concentrations élevées de chlorophylle (image du haut), colorées en vert et en jaune. Images acquises le 2 mars 2009. |
