(McGill University) A McGill-led international research team has completed the first global study of changes that occurred in the nitrogen cycle, at the end of the last ice age. Their study confirm that oceans are good at balancing the nitrogen cycle on a global scale. But the data also shows that it is a slow process that may take many centuries, raising worries about the effects of current changes in the ocean.

On Friday, June 14, filmmaker James Cameron delivered the DEEPSEA CHALLENGER, the only human-occupied vehicle currently able to access the deepest parts of the ocean, to Woods Hole Oceanographic Institution. Dr. Susan Avery, president and director of Woods Hole Oceanographic Institution, along with the scientific research community, welcomed Cameron and the submersible to its new home at Woods Hole Oceanographic Institution.

The federal government insists it is striving to avoid the Great Barrier Reef being listed "in danger" ahead of a crunch UN meeting, after rejecting a Senate recommendation to block new port developments near the World Heritage ecosystem.

The sustainability guru has seen environmental sustainability flourish over his career, but warns firms must move faster to address today's challenges.

A long-awaited threat management plan for Maui's dolphins is to be announced next month - but one MP has questioned whether the Government is going far enough to protect the critically endangered species.

The closest most of us will get to Antarctica is nature documentaries like Frozen Planet - but the white continent's relevance to us and our future is far greater than we think. Many of the clues to climate change lie buried within Antarctica's ice, waiting to be discovered by scientists racing to learn what global warming at the poles might mean for nations at the equator.

In a new study of spiny lobsters scientists from the University of Miami and Old Dominion studied the larval dispersal of this species in the Caribbean. The goal of the study was to describe the sources, sinks, and routes connecting the Caribbean spiny lobster metapopulation. The results led the team to propose marine resource management strategies that incorporate larval connectivity and "larval lobster credits" to sustain and rebuild exploited marine populations.

A new study shows that combining improved oyster restoration methods with limits on fishing in the upper Chesapeake could bring the oyster population back to the Bay in a much shorter period of time. The study led by Michael Wilberg of the University of Maryland Center for Environmental Science's Chesapeake Biological Laboratory assessed a range of management and restoration options to see which ones would have the most likelihood of success.

(University of California - Irvine) Ocean waters melting the undersides of Antarctic ice shelves, not icebergs calving into the sea, are responsible for most of the continent's ice loss, a study by UC Irvine and others has found.

Study solves the mystery of one of the most extreme adaptations in the animal kingdom: how marine mammals store enough oxygen to hold their breath for up to an hour.
