Clue to carbon storage in the Southern Ocean

Carbon emissions are drawn deep into the Southern Ocean by plunging currents, scientists have found, challenging the idea that carbon is locked away from the atmosphere by being absorbed across vast areas…
What does it matter how much rain falls on the ocean? For understanding climate, it matters quite a lot. Ines Hegedus-Garcia

Are the world’s wet regions becoming wetter and dry regions becoming drier?

Surprising evidence from the oceans suggests they are responding to warming at a faster rate than we previously thought. These changes are expressed by patterns of freshening and enhanced salinity in the…

Decade to decade changes in our climate – what’s really going on?

While most people now understand that the enhanced greenhouse effect means a much warmer planet, communicating regional shifts in weather remains a significant challenge. As with most complex science…

There will be “winners and losers in the oceans” as its chemistry changes. AAP

Some corals could survive a more acidic ocean

Internal “pumps” found in some corals may help them to endure gradual ocean acidification, giving rise to hope that coral reefs might escape climatic devastation, according to new research. A team of scientists…
Cameron’s voyage was a source of genuine wonder … so why the sinking feeling? Mark Thiessen/EPA

James Cameron and the Mariana Trench sparks titanic angst

Today as I ate lunch, Titanic, Terminator and Avatar director James Cameron was at the bottom of the Mariana Trench, the deepest point in the ocean. We know this for a couple of reasons. Not only did he…
