Decomposing oyster shells, made of calcium carbonate, act like an antacid pill and help generate alkalinity in the increasingly acidic oceans, a study finds.

A new study, published online May 19 in the journal Nature Geoscience, looks to the past to learn about the future of tropical climate change, and our ability to simulate it with numerical models.

The protection afforded to blue whales in New Zealand waters may need to be increased, now a study has found they may be more regular visitors to the South Taranaki Bight than previously thought.

Otago commercial fishermen have reacted with anger to a proposal to extend a ban on set-net fishing around the Otago Peninsula to help preserve yellow-eyed penguin colonies.

The Indo-Pacific warm pool was much dryer during the last ice age than today, because lower sea level exposed the Sunda Shelf. The large landmass, in place of the warm ocean, altered the atmospheric circulation, shifting convection further west into the Indian Ocean.

The first SIDS DOCK Pacific Regional Meeting reviewed the current work of the first phase of the SIDS DOCK Support Programme and discussed its next phase. SIDS DOCK is an initiative developed by small island developing States (SIDS) for SIDS to promote renewable energy, energy efficiency, and contribute towards sustainable development with support from the UN Development Programme (UNDP) and the World Bank.
