Coral Reefs in Palau Surprisingly Resistant to Naturally Acidified Waters

Ocean researchers working on the coral reefs of Palau in 2011 and 2012 made two unexpected discoveries that could provide insight into corals’ resistance and resilience to ocean acidification, and aid in the creation of a plan to protect them.

The team collected water samples at nine points along a transect that stretched from the open ocean, across the barrier reef, into the lagoon and then into the bays and inlets around the Rock Islands of Palau, in the western Pacific Ocean. With each location they found that the seawater became increasingly acidic as they moved toward land. (more…)

Acidifying oceans could spell trouble for squid

New study reveals more acid seas could alter early development of Atlantic longfin squid

Acidifying oceans could dramatically impact the world’s squid species, according to a new study led by Woods Hole Oceanographic Institution (WHOI) researchers and just published online in the journal PLOS ONE. Because squid are both ecologically and commercially important, that impact may have far-reaching effects on the ocean environment and coastal economies, the researchers report.

“Squid are at the center of the ocean ecosystem—nearly all animals are eating or eaten by squid,” says WHOI biologist T. Aran Mooney, a co-author of the study. “So if anything happens to these guys, it has repercussions down the food chain and up the food chain.” (more…)

Global Warming Refuge Discovered Near At-Risk Pacific Island Nation of Kiribati

Ocean currents may mitigate warming near handful of equatorial islands

Scientists predict ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems.

But a new study shows that climate change could cause ocean currents to operate in a way that mitigates warming near a handful of islands right on the equator.

Those islands include some of the 33 coral atolls that form the nation of Kiribati. This low-lying country is at risk from sea-level rise caused by global warming. (more…)
