The increased freshwater from melting Antarctic ice sheets plus increased wind has reduced the amount of oxygen in the Southern Ocean and made it more acidic and warmer, according to new research led by University of Arizona geoscientists.

Scientists have shown for the first time that brittle stars use vision to guide them through vibrant coral reefs, thanks to a neat colour-changing trick.

World leaders are currently updating the laws for international waters that apply to most of the world's ocean environment. This provides a unique opportunity, marine scientists argue this week, to introduce new techniques that allow protected zones to shift as species move under climate change.

NOAA’s Office of Ocean Exploration and Research and the ocean data and technology company Ocean Infinity have announced a new agreement to develop deep-water autonomous technologies that can gather ultra-high-resolution ocean information.

Scientists have discovered dozens of new coral species on a recent voyage along the length of the Great Barrier Reef that will provide valuable insights to aid conservation and management of Australia’s unique World Heritage site.

Using the latest satellite technology from the European Space Agency (ESA), scientists from the University of Bristol have been tracking patterns of mass loss from Pine Island -- Antarctica's largest glacier.

The Paris Agreement, adopted in 2015 by 175 parties, aims to limit global warming to well below 2°C compared to pre-industrial levels.
