NewsStill standing but mostly dead: Recovery of dying coral reef in Moorea stalls
In 2019, a marine heat wave struck a coral reef on the island of Moorea in French Polynesia, killing much of the coral and the beneficial algae that colonized it. A long-term study of the area is challenging scientists’ understanding of the cycles of destruction and repair that can occur on a coral reef.

NewsResearchers uncover hidden genetic world in Antarctic Waters
Researchers have completed the most comprehensive survey to date of DNA associated with Southern Ocean microbes, paving the way for a better understanding of their role in climate change. At least a third of the genes identified are missing from existing marine gene catalogs.

NewsNew study finds deep ocean microbes already prepared to tackle climate change
A new study demonstrates that the microbe Nitrosopumilus maritimus may already be adapting well to warmer, nutrient-poor waters. Researchers predict that these adaptable iron-dependent ammonia-oxidizing archaea will play an important role in reshaping ocean-nutrient distribution in a changing climate.

NewsHitchhiking bacteria can alter marine snow's role as a carbon sink
Researchers have found that when bacteria hitch a ride on marine snow particles, the microbes can eat away at calcium carbonate, which is an essential ballast that helps particles sink.

NewsToxic algal bloom takes heavy toll on mental health
The year-long algal bloom along the South Australian coastline has not only devastated marine life and triggered health risks for humans and pets: it has also had a significant psychological impact on local residents, according to new research.

NewsThe new ‘forever’ contaminant? Study raises alarm on marine fiberglass pollution
Researchers investigating fibreglass contamination of an estuary looked at the biofilm and the deeper sediment layer where sediment‑dwelling invertebrates live and feed. They found fibreglass particles at several of the surface biofilm testing sites and 96 per cent of the sediment testing sites.

NewsMicroscopic plankton reveal tropicalization of the Mediterranean Sea
A recent study of the western Mediterranean demonstrates that the expansion of microscopic warm-water species provides a clear and early indication of tropicalization impacts on marine ecosystems.

NewsCorals in extreme coastal bays show greater resilience to climate stress
Corals living in coastal bays with strongly fluctuating temperatures and environmental conditions are better able to withstand heat and other stressors than their counterparts on more stable reefs.

NewsOysters play unexpected role in protecting blue crabs from disease
Oysters famously filter their surrounding water, but it turns out they are removing more than algae and excess nutrients. New research shows they can also reduce the spread of disease in nearby marine species, including Chesapeake Bay’s prized blue crabs.

NewsSediment core yields evidence of an unexpected climate feedback in Antarctica
Researchers have concluded that global warming may lead to reduced uptake of carbon dioxide than at present in the Pacific sector of the Southern Ocean if the West Antarctic Ice Sheet, which is considered unstable, continues to shrink.

NewsCorals sleep like us, but their symbiosis does not rest
A study has revealed that corals also sleep, despite not having a nervous system, while their microbiome remains awake. For the first time, a biological day-night pattern that transcends the individual and helps sustain a symbiotic relationship has been identified in situ.

NewsScientists solve 66 million-year-old mystery of how Earth’s greenhouse age ended
Experts studying foraminifera fossils have discovered that concentrations of calcium in the sea dropped by more than half across the last 66 million years, which likely caused Earth’s massive drop in temperature.
-
NewsPositive interactions dominate among marine microbes, six-year study reveals
Researchers have found that marine microbes interact in ways that benefit one another more often than they eat each other or compete. Periods of elevated ocean temperatures, usually times of stress for these microbes because of a dearth of nutrients, resulted in even more of these positive interactions.

NewsSeawater microbes offer new, non-invasive way to detect coral disease, study finds
Researchers have discovered that microorganisms in seawater surrounding corals provide a powerful indicator of coral disease, potentially transforming how reef health is monitored worldwide.

News£3.7 million project aims to provide unprecedented analysis of mesophotic coral reefs
Scientists are to carry out an unprecedented assessment of the response and resilience of mesophotic coral ecosystems – coral reef communities found at depths of between 30m and 150m in tropical regions – to the temperature shifts predicted under future climate change.

NewsTeam shows how viral lysis of blue-green algae enhances ecosystem-scale productivity
Newly published interdisciplinary research shows viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water.

NewsAntibiotics in sediments may quietly boost greenhouse gas emissions
A study shows that pharmaceutical pollution alters nitrogen cycling and greenhouse gas emissions in coastal sediments. Even environmentally relevant antibiotic concentrations increased N₂O release, suggesting that widespread contamination may enhance estuarine climate forcing.

NewsBacteria resisting viral infection can still sink carbon to ocean floor
Researchers exploring the mechanisms of phage resistance and its effects on the ecological jobs done by ocean bacteria found that some of the mutations studied don’t interfere with the bacteria’s ability to carry out their job of capturing and sinking carbon to the ocean floor.
