Something for us Reefers to think about
Link to this And this is another one The Canary is Dead ? the Phoenix Islands a case study on the catastrophic degradation of the reefs of the Phoenix Islands studied by PCRF in 2004 The Planetary Coral Reef Foundation?s (PCRF) research vessel, Heraclitus, visited the remote Phoenix Islands of the Central Equatorial Pacific Ocean in Nov/Dec 2004 and the crew discovered that a massive coral mortality event had occurred in Kanton Island between June 2002 and November 2004. There is little or no significant input from any source of land based pollution on Kanton 2,3,4 and no obvious populations of coral predators such as Acanthaster planci. The most plausible explanation for the mass mortality of coral species and coverage is death due to persistent, excessive water temperatures recorded in the Phoenix Islands by NOAA/NESDIS (www.osdpd.noaa.gov) from the months of August 2002 through March 2003. These islands were considered by Dr. David Obura, a specialist in coral reefs, to be one of ?Earth?s last pockets of primal ocean?those underwater havens that have remained unspoiled as long as the ocean can remember?1. Inside the lagoon of Kanton Island the luxuriant community of Acropora spp. corals suffered near 100% mortality and there was an estimated 62% mortality of corals along the reefs outside the lagoon. The fish populations were not as noticeably affected yet and a total of 153 species of fish were identified along transects.
