Papahānaumokuākea Marine National Monument issued an updated Coral
Bleaching Current Conditions report last week. This report can be
viewed on our website at:
The main findings of the update are:
Analysis of satellite data by NOAA’s Coral Reef Watch Program estimates
that accumulated temperature stress is approaching thresholds known to
cause coral bleaching, but has not currently exceeded these levels
Coral Reef Watch predictions suggest that the bleaching risk is greatest
to Papahānaumokuākea’s northern atolls: Kure, Pearl and Hermes, and Midway.
These findings are consistent with measurements of sea water temperature
recorded by a buoy at Kure Atoll. According to NOAA’s Coral Reef
Ecosystem Division, current temperatures at Kure are above average for
this time of year, based on a 30-year record.
A research cruise conducted by NOAA in August did not observe any
incidents of coral bleaching. A September NOAA cruise is closely
monitoring the situation, with an expectation that sea temperatures will
reach their highest levels for the year in mid to late September.
