Summary
[edit]DescriptionPhytoplankton bloom in the Ross Sea - Antarctica.jpg |
English: Seasons in the Ross Sea are marked by ice freezing and melting, and these processes mix the seawater while redistributing salt and nutrients. During the austral spring and summer, the influx of nutrients along the coastal area of Antarctica turns the water green as a consequence of massive phytoplankton blooms. These blooms are so large that they can be seen by satellites: this image, acquired by one of the Copernicus Sentinel-3 satellites on 17 January 2021, show a massive phytoplankton bloom (~200 km long) near the Drygalski ice tongue. Blooms are indicators of the health of a marine ecosystem, and their monitoring is a key component of effective management of coastal and oceanic resources. The Copernicus Sentinel missions provide high frequency data useful for monitoring water quality of coastal waters. |
