Short summary
The Adriatic Sea has become warmer and saltier over the past two decades, and the change is fastest at depth: below 700 m it now warms about six times faster than the rest of the Mediterranean. Using 75 years of ship and float measurements, we show that salty layers at the sea surface became common after 2014 and that the salty intermediate water no longer sits at one depth. These changes may alter how oxygen and nutrients reach the deep sea.
