People walk among bleached algae that would usually be underwater on the shoreline after the sea level around the Maltese islands went down by a record-breaking 50cm in Marsascala, Malta February 23, 2023. The drop in sea level was triggered by the dynamics of the Mediterranean Sea, and in particular density changes due to temperature and salinity, as well as water exchanges with the Atlantic Ocean at the Strait of Gibraltar, according to local media.
