This Copernicus Sentinel-2 picture captures algal bloom swirls within the north Adriatic Sea, alongside the coast of Italy.
Zoom in to discover this picture at its full 10 m decision or click on on the circles to be taught extra.
An algal bloom describes the fast development of phytoplankton – microscopic marine crops that drift on or close to the ocean floor. The chlorophyll that phytoplankton use for photosynthesis collectively tints the encircling waters, offering a way of detecting these tiny organisms from house with sure satellite tv for pc sensors.
With its 13 spectral channels, Copernicus Sentinel-2’s imager can be utilized to detect the extent and evolution of those blooms. On this picture from 12 August 2024, the emerald-green streaks, eddies and whirls of the bloom, combined by winds and currents, are clearly seen and canopy an space of round 9000 sq km.
Algal blooms are a pure and important a part of ocean life. Heat climate, with floor water temperatures reaching 29°C, and calm seas in July and August 2024 led to a rise in mucilage within the Adriatic Sea. Right here, white threads of mucilage might be noticed throughout the bloom. Currents and winds contributed to concentrating the mucilage into seen patches alongside the coast, interfering with fishing actions and making the waters much less enticing for swimmers.
Satellite tv for pc information like these from Sentinel-2 can be utilized to trace the expansion and unfold of blooms and will help native authorities to implement well timed methods to cut back the impression on tourism and fishing.
