New research shows how marine debris from continents across the southern hemisphere threatens Antarctica’s remote coastline and unique marine ecosystems. Foreign organisms might be hitching a ride.

Canadians are no strangers to cold winters, when everything in nature appears to be frozen solid. However, under the ice cover of lakes, many animals remain active during the winter.
Using cameras and trackers attached to Australian sea lions, we explored previously unmapped ocean habitats off the South Australian coast. The data also fed into predictive computer models.
A clever approach to restoring Australia’s native oyster and mussel reefs in Queensland’s Moreton Bay is catching on, giving community groups a way to get involved in their local patch.
Kelp seaweed spores are being grown on small rocks and waste scallop shells as part of a trial exploring how to regenerate the UK’s coastal kelp forests.
This marine ecosystem is so important it’s one of the main reasons the federal government has greatly reduced the area available for offshore wind farms in the region.
Governments all over the world are propping up overfishing. Now scientists have penned an open letter calling on trade ministers to implement stricter regulations against harmful fisheries subsidies.
Any plan to dam or extract water from some of Australia’s last wild rivers must carefully consider the consequences. Prawn, mud crab and barramundi fisheries could suffer in the Gulf of Carpentaria.
Environmental degradation of Nigeria’s Niger Delta region is causing poverty as well as food insecurity, increased crime and conflict.
The first comprehensive assessment of trends in Southern Ocean ecosystems reveals an urgent need to address climate change. The summary for policymakers can guide decision-makers.
Through regulation, enforcement and monitoring, fisheries management can lead to recoveries in shark and ray populations.
We cannot afford to ignore kelp – these vibrant underwater forests have sustained people and ecosystems for centuries, and continue to do so today.
Scientists are predicting a record sargassum bloom in 2023. It’s already starting to wash up on beaches in Florida and the Caribbean and cause a stink.
By adapting and applying existing policies, South Africa can protect and restore its critical ‘blue carbon’ sinks.
Artificial lighting from cities illuminates coastal waters and can change the physiology and behaviour of marine organisms.
New Zealand may see more sponge bleaching as the northern coastlines are already experiencing almost continuous marine heatwave conditions, expected to extend into the coming summer.
Australia must map out the best sites for generating the most electricity with the least environmental impact.
A new biodiversity index captures the climate risk for nearly 25,000 marine species and their ecosystems and lays the groundwork for climate-smart approaches to management and conservation.
As the dead whales decompose, an astonishing and rare chain of events is likely to flow through the marine ecosystem – ultimately leading to an explosion of activity and new life.
The photographs show how climate change is disrupting our marine ecosystems – sometimes in ways previously unknown to marine scientists.
