Protective ship coatings as an underestimated source of microplastic pollution
Shipping traffic can be a major source of microplastics, especially out in the open ocean. In a new study, a team of environmental geochemists from the University of Oldenburg (Germany) for the first time provides an overview of microplastics mass distribution in the North Sea. The scientists found that most of the plastic particles in water samples taken in the south-eastern North Sea originate from binders used in marine paints. Their hypothesis is that ships leave a kind of 'skid mark' in the water. (2021-02-23)

Sweet marine particles resist hungry bacteria
Rather sweet than salty: In the ocean microalgae produce a lot of sugar during algae blooms. These enormous quantities of algal biomass are normally recycled rapidly by marine bacteria, degradation process that is an important part of the global carbon cycle. Especially sugars have been considered as easily digestible and therefore poor candidates for natural carbon sequestration. Now scientists from Bremen revealed: There exists a sugar in algae that resists rapid microbial degradation and stores carbon during spring blooms. (2021-02-19)

Study reveals energy sources supporting coral reef predators
Since Charles Darwin's day, the abundance of life on coral reefs has been puzzling, given that most oceanic surface waters in the tropics are low in nutrients and unproductive. But now research, led by Newcastle University and published in in the journal Science Advances, has confirmed that the food web of a coral reef in the Maldives relies heavily on what comes in from the open ocean.

Poking the paradigm
Deprive a mountain range of its wolves, and soon the burgeoning deer population will strip its slopes bare. ''I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer,'' wrote ecologist Aldo Leopold in his landmark 1949 title ''A Sand County Almanac.'' (2021-02-17)

Turf wars: Ocean acidification and feedback loops lock in turf algal systems
Researchers from the University of Tsukuba have found that seawater acidification locked marine communities of turf algae in a stable state, preventing the growth of kelp and coral species. The degraded turf algal systems were stabilized by feedback loops (control mechanisms in a system). This study will contribute to efforts to manage shifts from complex and diverse marine ecosystems to degraded ones, and better conserve coastal ecosystems and their contributions to human wellbeing.

Healthy oceans need healthy soundscapes
Rain falls lightly on the ocean's surface. Marine mammals chirp and squeal as they swim along. The pounding of surf along a distant shoreline heaves and thumps with metronomic regularity. These are the sounds that most of us associate with the marine environment. But the soundtrack of the healthy ocean no longer reflects the acoustic environment of today's ocean, plagued with human-created noise. (2021-02-05)

Hidden world just below the surface
A team of scientists from NOAA's Pacific Islands Fisheries Science Center, the University of Hawai'i at Mānoa, Arizona State University and elsewhere have discovered that a diverse array of marine animals find refuge in so-called 'surface slicks' in Hawai'i. These ocean features create a superhighway of nursery habitat for more than 100 species of commercially and ecologically important fishes, such as mahi-mahi, jacks, and billfish. Their findings were published today in the journal Scientific Reports. (2021-02-04)

MARLIT, artificial intelligence against marine litter

Research illuminates lobsters' genetic response to changing climate
The American lobster, which supports the most valuable fishery in North America, may be more susceptible to climate change than previously thought. Studies of the early life stages of lobsters have concluded that ocean acidification, compared to warming, had limited impact on growth and metabolism. According to new research, their genes tell a different story, which could help anticipate the long-term effects of climate change for one the nation's most precious natural resources. (2021-01-28)

Marine heatwaves becoming more intense, more frequent
When thick, the surface layer of the ocean acts as a buffer to extreme marine heating--but a new study from the University of Colorado Boulder shows this ''mixed layer'' is becoming shallower each year. The thinner it becomes, the easier it is to warm. The new work could explain recent extreme marine heatwaves, and point at a future of more frequent and destructive ocean warming events as global temperatures continue to climb. (2021-01-28)
