Nutrient pollution emptying into seas from cities, towns and agricultural land is changing the sounds made by marine life – and potentially upsetting navigational cues for fish and other sea creatures, a new University ...
Human actions are changing the oceans' chemistry. Pollution washes in from the coasts, iron-laden dust blows in from increasingly arid land, greenhouse gases raise surface temperatures and carbon dioxide levels. To predict ...
Coral reefs are declining around the world because a combination of factors—overfishing, nutrient pollution, and pathogenic disease—ultimately become deadly in the face of higher ocean temperatures, researchers have concluded.
A recent paper published in PLOS ONE uses geochemical and fossil evidence from the period of global warming at the end of the last ice age to reconstruct the depth and extent of ocean areas with dissolved oxygen below those ...
A new study published today identifies a set of features common to all ocean ecosystems that provide a visual diagnosis of the health of the underwater environment coastal communities rely on. Together, the features detail ...
Prodding glacial sludge with their hands, a huddle of scientists marvel at the sight of a strange-looking millipede wriggling out of a sample lifted from the Arctic seabed.
A world-first global analysis of marine responses to climbing human CO2 emissions has painted a grim picture of future fisheries and ocean ecosystems.
Humans are changing the 'landscape of fear' in oceans in many more ways that previously thought, and the effects of these changes can ripple through ocean ecosystems in a wide variety of surprising ways, research by Dr Elizabeth ...
(Phys.org)—Coral reefs are the most diverse marine ecosystems, biodiversity hotspots now under anthropogenic threat from climate change, ocean acidification and pollution. Efforts are underway to protect and expand shrinking ...
A new study by WCS (Wildlife Conservation Society) has found that coral reef diversity 'hotspots' in the southwestern Indian Ocean rely more on the biomass of fish than where they are located, a conclusion that has major ...
