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.

Aquaculture's role in nutrition in the COVID-19 era
A new paper examines the economics of an aquaculture industry of the future that is simultaneously environmentally sustainable and nutritious for the nearly 1 billion people worldwide who depend on it.

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.

15-foot-long skeleton of extinct dolphin suggests parallel evolution among whales
A report offers a detailed description of the first nearly complete skeleton of an extinct large dolphin, discovered in what is now South Carolina. The 15-foot-long dolphin (Ankylorhiza tiedemani comb. n.) lived during the Oligocene -- about 25 million years ago -- and was previously known only from a partial rostrum (snout) fossil.

Born to be a cannibal: Genes for feeding behavior in mandarin fish identified
Some mandarin fish species (Sinipercidae) are pure fish-eaters, which feed exclusively on living juvenile fish - also of their own species. A research team has described the genome of four mandarin fish species and thus also identified genes for cannibalistic eating behavior. Knowledge of the connections between the genome and feeding behavior is of interest for sustainable aquaculture.

Stress testing 'coral in a box'
Coral death is impacting oceans worldwide as a consequence of climate change. The concern is that corals cannot keep pace with the rate of ocean warming. In particular, because a temperature increase of only one degree Celsius can make the difference between healthy and dying coral reefs. Some corals, however, are more resistant to increasing temperatures. In order to effectively protect coral reef habitats, it is important to identify which corals and reef sites are more resistant and thus have a greater chance of survival.

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.

Algae species discovered infesting NW Hawaiian waters has been identified
A newly-identified, fast-growing species of algae poses a major threat to coral reefs and the ocean ecosystem in the northwestern Hawaiian Islands.

Nutrients in microalgae: An environmentally friendly alternative to fish
Microalgae could provide an alternative source of healthy omega-3 fatty acids for humans while also being more environmentally friendly to produce than popular fish species. The study offers an initial indication of the environmental effects of producing microalgae in Germany.

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.

Marine algae from the Kiel Fjord discovered as a remedy against infections and skin cancer
Using state-of-the-art approaches coupled with bio- and cheminformatics and machine learning, researchers have succeeded in discovering new, bioactive components of the Baltic Sea Baltic Sea seaweed Fucus vesiculosus and its fungal symbiont against infectious bacteria or skin cancer.

Microscope allows gentle, continuous imaging of light-sensitive corals
Many corals are sensitive to bright light, so capturing their dynamics with traditional microscopes is a challenge. To work around their photosensitivity, researchers developed a custom light-sheet microscope (the L-SPI) that allows gentle, non-invasive observation of corals and their polyps in detail over eight continuous hours, at high resolution.
