The NOAA Coral Reef Watch (CRW) daily global 5km satellite coral bleaching Degree
Heating Week (DHW) product presented here shows accumulated heat stress, which can lead to coral bleaching and death.
The scale ranges from 0 to 20 °C-weeks. The DHW product accumulates the instantaneous bleaching heat stress,
measured by CRW's Coral Bleaching HotSpot, during the most recent
12-week period. It is directly related to the timing and intensity of coral bleaching. Significant
coral bleaching usually occurs when the DHW value reaches 4 °C-weeks. By the time the DHW
value reaches 8 °C-weeks, severe, widespread bleaching is likely and significant mortality can
be expected.
