Arctic Ocean changes driven by sub-Arctic seas
New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.

Sea surface temperature has a big impact on coral outplant survival
A new study has shown that coral outplant survival is likely to drop below 50% if sea surface temperatures exceed 30.5 degrees Celsius and that survival rates can also be predicted by considering temperature conditions in the year prior to outplanting.

Scientists urge caution, further assessment of ecological impacts above deep sea mining
A new study argues that deep-sea mining poses significant risks, not only to the area immediately surrounding mining operations but also to the water hundreds to thousands of feet above the seafloor, threatening vast midwater ecosystems. Further, the scientists suggest how these risks could be evaluated more comprehensively to enable society and managers to decide if and how deep-sea mining should proceed.

A 'regime shift' is happening in the Arctic Ocean
Scientists find the growth of phytoplankton in the Arctic Ocean has increased 57 percent over just two decades, enhancing its ability to soak up carbon dioxide. While once linked to melting sea ice, the increase is now propelled by rising concentrations of tiny algae.

A new look at deep-sea microbes
Microbes found deeper in the ocean are believed to have slow population turnover rates and low amounts of available energy. But a new examination of microbial communities found deeper in seafloor sediments and around hydrocarbon seepage sites has found they have more energy available and a higher population turnover. The deeper sediments in the seepages are most likely heavily impacted by the material coming up from the bottom, which means that the seep could be supporting a larger amount of biomass than previously thought.

Two climate patterns predict coral bleaching months earlier
A new study may help researchers predict coral bleaching months earlier than current tools, and, for the first time, may help predict invasion events of coral-eating crown-of-thorns starfish.

Tackling coral reefs' thorny problem: Crown-of-thorns starfish
Researchers have revealed the evolutionary history of the crown-of-thorns starfish -- a predator of coral that can devastate coral reefs. Their findings shed light on how the populations of these starfish have changed over time and could potentially help reduce their ecological destruction.

Climate change may cause extreme waves in Arctic
Extreme ocean surface waves with a devastating impact on coastal communities and infrastructure in the Arctic may become larger due to climate change, according to a new study.

Fresh call for seagrass preservation
An increase in carbon dioxide emissions equivalent to 5 million cars a year has been caused by the loss of seagrass meadows around the Australian coastline since the 1950s. Researchers calculated that around 161,150 hectares of seagrass have been lost from Australian coasts since the 1950s. This has resulted in a 2 per cent increase in annual carbon dioxide emissions from land-use change.

Microplastic pollution harms lobster larvae, study finds
Microplastic fiber pollution in the ocean impacts larval lobsters at each stage of their development, according to new research. A study reports that the fibers affect the animals' feeding and respiration, and they could even prevent some larvae from reaching adulthood.

First direct evidence of ocean mixing across the Gulf Stream
A new study provides first direct evidence for Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and biological productivity from Florida to Newfoundland and along the western coast of Europe.

MOSAiC floe: Sea ice formation
The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018.

Rising water temperatures could endanger the mating of many fish species
In a new meta-study, experts have published ground-breaking findings on the effects of climate change for fish stock around the globe.

Plastic recycling from Europe is being dumped in Asian waters
New research has for the first time quantified the volume of plastic from European countries (EU, UK, Switzerland and Norway) that contributes to ocean littering from exported recycling.

Research reveals fishing pressures affect tropical and temperate reefs differently
An international team of researchers focused on what can happen to ocean ecosystems when fishing pressure increases or decreases, and how this differs between tropical to temperate marine ecosystems. The team found ecosystems do not respond universally to fishing.

Historic floods reveal how salt marshes can protect us
By digging into major historic records of flood disasters, a research team reveals that the value of nature for flood defense has actually been evident for hundreds of years.

First completely remote at-sea science expedition in Australia's coral sea marine park
Scientists working remotely with Schmidt Ocean Institute, one of the only at-sea science expeditions to continue operating during the global pandemic, have completed a first look at deep waters in the Coral Sea never before seen.
