“…Sea temperatures were cooled by 0.3-3.2°C (mean Ϯ SEM ϭ 1.5°C Ϯ 0.10, n ϭ 53) by hurricanes or tropical storms whose tracks passed within 400 km of a site, which is consistent with observations made in Okinawa (15,17). When storms were Ͼ400 km from a site, ⌬°C (magnitude of cooling) ranged from 0.1 to 0.9°C (mean Ϯ SEM ϭ 0.5°C Ϯ 0.09, n ϭ 10).…”

Recent, global mass-mortalities of reef corals due to record warm sea temperatures have led researchers to consider global warming as one of the most significant threats to the persistence of coral reef ecosystems. The passage of a hurricane can alleviate thermal stress on coral reefs, highlighting the potential for hurricaneassociated cooling to mitigate climate change impacts. We provide evidence that hurricane-induced cooling was responsible for the documented differences in the extent and recovery time of coral bleaching between the Florida Reef Tract and the U.S. Virgin Islands during the Caribbean-wide 2005 bleaching event. These results are the only known scenario where the effects of a hurricane can benefit a stressed marine community.coral bleaching ͉ hurricane cooling ͉ thermal stress

“…Apart from the Great Barrier Reef [17] few studies have yet described integrated physical mechanisms through an analysis of series of measurements spanning several years over large reef lagoons.

The variability in salinity and temperature in the southwest lagoon of New Caledonia (2,100 km 2 ) under non-storm conditions is analyzed using a 4-year data set (1997)(1998)(1999)(2000)(2001). Seasonal and interannual variations in salinity are amplified near shore.Temperature is larger in bays than in the open lagoon during summer, the reverse is true in winter. El Niño Southern Oscillation (ENSO) related nearshore temperature variations parallel those at regional scale, but with seasonal variations amplified. Haline stratification, if any, is enhanced in coastal areas. RésuméLes distributions de salinité et de température dans le lagon sud-ouest de NouvelleCalédonie (2100 km 2 ) sont analysées en regard de leurs variations régionales à partir de 4 ans de mesures (1997)(1998)(1999)(2000)(2001). Les variations saisonnières et interannuelles de salinité sont amplifiées à la côte. La température est plus élevée près de la côte qu'en milieu de lagon en été austral et y est plus faible en hiver. Le phénomène ENSO (El Niño Southern Oscillation) amplifie ces variations. En cas de stratification haline, celle-ci est également amplifiée à la côte. Les baies jouent ainsi un rôle de caisse de résonance dans le fonctionnement physique du lagon, avec des répercussions tant dans la répartition des espèces que dans la vulnérabilité des milieux (blanchissement des coraux).

“…Cloud cover reduces the amount of solar radiation that can heat up the water, yet clouds reflect some of the long wave radiation emitted by the water back onto the water surface. Ocean currents can transport warmer water into cooler regions and therefore may also contribute to coral bleaching [4].…”

Abstract-Red Sea tourism is highly dependent on the natural resources especially the diversity of Egyptian coral reefs. Local coral bleaching monitoring framework was applied in this study to investigate the threats. The target area included the six richest spots of coral reefs in terms of bio-diversity and tolerance to various stresses. Assessment of the applicability and accuracy of remotely sensed sea surface temperature (SST) data in the region were assessed by comparing them with in situ measurements. The annual and seasonal sea surface temperature (SST) trends have been investigated. Twenty three years (1990-2013) of SST data were used to assure accurate estimation of the monthly maximum mean (MMM) of SST Climatology. In addition, the Hot Spots were calculated for each location during last 23 years. A thermal stress index degree heating weeks (DHW) was calculated in order to assess the accumulative effect of heat stress. This work suggests the bleaching threshold limit for each location based on the long-term analysis. The thermal analysis results were in close agreement with the recorded bleaching events (2010 and 2012). Moreover, they revealed some historical events which may be not recorded properly.
