January 6, 2025: The Falkland Islands are flowering! ..Well, it's experiencing spectacular phytoplankton blooms that dazzle in the productive South Atlantic waters around the British Overseas Territory off Argentina. ..Communities of the tiny aquatic organisms persisted into the long days of the Southern Hemisphere summer, painting surface waters in shades of green and blue into late December..The leer más OCI (Ocean Color Instrument) on NASA's PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite acquired this image of the bloom and its intricate swirls around the Falklands on December 28, 2024. In the waters of the Patagonian Shelf-break front, airborne dust from the land, iron-rich currents, and upwelling from the depths provide abundant nutrients for phytoplankton. These floating sunlight harvesters support rich aquatic diversity and productive fisheries...The various colors visible in the image likely reflect a mix of phytoplankton communities. The proportions of these communities change throughout the months-long bloom based on nutrient availability and other environmental factors. ..In this scene, chlorophyll-rich diatoms and other phytoplankton types that color the water green may be giving way to coccolithophores, said Ivona Cetinić, an oceanographer at Morgan State University and member of NASA's Ocean Ecology lab..."Coccolithophores love long days and lots of sunshine, so they are probably dominating now," she said. ..Armoured with plates of highly reflective calcium carbonate, these organisms make surface waters appear a milky turquoise-blue. The coccolithophore bloom that emerges each year off Patagonia is part of the so-called Great Calcite Belt. Stretching around the planet in southern waters, the region is thought to play a major role in the planet's carbon cycle...The distribution of colours in the image also reveals complexities in the ocean's leer menos
