Degree Heating Weeks

Degree Heating Weeks (DHW) er en termisk stressmetrik, der kvantificerer akkumuleret varmeeksponering over en koralblegningsgrænse, beregnet ud fra satellitdata for havoverfladetemperatur. DHW blev udviklet af NOAA's Coral Reef Watch-program i 2003 og giver et standardiseret indeks til global forudsigelse og overvågning af koralblegningsstress. Metrikken kombinerer intensitet og varighed af termiske anomalier for at estimere den kumulative fysiologiske stress på koralpopulationer.
