The Great Barrier Reef has lost half its coral cover in the last 27 years. Mainly due to storm damage and crown of thorns starfish attacks, according to a new report.

Bioeroding sponges profit from ocean acidification, and are the winners of the global climate changes on the expense of coral reefs.

UK oceanographers have thought of a novel way to measure the global ocean – weigh it. Thus, solving the biggest problem in sea level science.

A study reveals an unexpected aspect of deforestation in Brazil. Slash and burn has left huge amounts of charcoal in the soil, which is transported by rivers into the Atlantic Ocean. The effects of this on the oceans are still unknown.

Research from the University of Southampton and the National Oceanography Centre, Southampton has found that an imbalance of nutrients in reef waters can increase the bleaching susceptibility of reef corals.

A team of international scientists have found that soil erosion, land degradation and climate change pose a mounting threat to coastal reefs and their ecosystems in the western Indian Ocean.

Rapid rates of coral reef growth have been identified in sediment-laden marine environments, conditions previously believed to be detrimental to reef growth.

Ultraviolet radiation has caused a steep increase in deaths among marine animals and plants, according to an international team including scientists at the Oceans Institute of The University of Western Australia.

The heat wave resulted in fewer large cool-water seaweeds and increased numbers of tropical fish.

Some coral reef fish may be better prepared to cope with rising CO2 in the world’s oceans – thanks to their parents.
