Abstract:
"CRW partners in CNMI reported that the period of hot, humid, still conditions throughout August and September 2013 resulted in localized, severe bleaching in Saipan, especially in the Saipan lagoon and Pau Pau Beach areas. Acropora stands sustained moderate to severe bleaching, with some bleaching induced mortality, and Pocillopora damicornis and Isopora palifera colonies suffered substantial bleaching induced mortality. In Tinian harbor, only slight paling was noted on P. damicornis colonies, and Acropora thickets showed signs of bleaching but very little death. In Guam, partners reported that moderate to severe bleaching was observed throughout August 2013 in several large Acropora stands (on shallow reef flats), and fairly widespread paling and either partial or full-colony bleaching was observed in various other Acropora spp., Montipora spp., Pocillopora spp., Isopera spp., and several other genera on the reef flat, margin, and outer reef slope to a depth of around 6-8 m. A moderate degree of mortality was observed in bushier Acropora spp., but the mortality could not be attributed directly to thermal stress and bleaching. CRW's long-term satellite record indicates that Guam and CNMI are usually free of major coral bleaching thermal stress; however, 2013 suffered the most significant thermal stress seen in the CNMI."
