You are looking at an example twice-weekly global 50km coral bleaching Degree Heating Week (DHW) product image. Black areas had not experienced any bleaching heat stress over the prior three months, based on satellite observations. Blue areas (1-3 DHWs) had low to intermediate stress accumulate over the prior three months. Green to yellow areas (4-9 DHWs) had high heat stress (leading to significant coral bleaching at 4 or more DHWs, or severe, widespread bleaching and significant mortality at 8 or more DHWs). Orange to purple areas (10-16 DHWs and higher) had very high, prolonged heat stress leading to widespread coral mortality. Please click here for more information.
