This Copernicus Sentinel-2 image acquired on 11 July 2023 shows unusual emerald green waters in the Bay of Naples, Italy.
According to the Regional Environmental Protection Agency of Campania, where Naples is, this phenomenon has already happened in past summers.
A combination of high sea temperatures and a slower water exchange in the Bay led to a proliferation of phytoplankton. Recent tests on the waters reported a sea temperature of about 29 degrees, lower salinity than average but a higher-than-usual concentration of chlorophyll.
