NewsTiny poops in the ocean may help solve the carbon problem
Zooplankton could capture carbon dioxide originating from Earth’s atmosphere and deposit it deep into the sea as feces. The new technique mooted consists of spraying clay dust on the surface of the ocean at the site of large blooms of phytoplankton.

NewsSpecialist under-ice species at risk as Arctic warms
’Specialist’ lifeforms that live under Arctic sea ice are at risk as the ice retreats, new research shows. Scientists studied microscopic organisms in four environments – open ocean, river mouths, coasts and under sea ice – in the sea off northern Canada.

NewsClimate change threatens key ocean plankton groups
Planktonic foraminifera species may face unprecedented environmental conditions by the end of this century, potentially surpassing their survival thresholds, with extinctions impacting marine ecosystems and the ocean’s carbon storage capacity.

NewsWorld’s first regular flight-based red tide ocean observation to launch in summer 2025
Hokkaido Air System Co., Ltd. will equip one of its aircraft with an external camera to commence the world’s first regular flight-based red tide monitoring starting in the summer of 2025.

NewsScientists team up with NASA to unlock ocean phytoplankton secrets from space
Scientists have teamed up with NASA on a new-generation satellite mission to study the colour of the ocean from space, providing vital information about ocean health and its role in climate regulation.

NewsA metabolic secret of ethane-consuming archaea unraveled
Scientists have presented a study on the degradation of ethane, the second most abundant alkane in seeps on the deep seafloor. They characterized enzymes involved in the process and found that their reaction breaks an established dogma in the field of anaerobic biochemistry.

NewsClimate change accelerates vulnerability and loss of resilience of key coral species in the Med
Red gorgonians exposed to marine heatwaves decrease the ability to resist and recover from other disturbances.

NewsReport on Great Barrier Reef shows coral cover was increasing before onset of serious bleaching, cyclones
Coral cover has increased in all three regions on the Great Barrier Reef and is at regional highs in two of the three regions according to a report by the Australian Institute of Marine Science (AIMS) - but the results come with a note of caution.

NewsCarbohydrate produced by bacteria triggers marine biofouling
The carbohydrate portion of a complex molecule, called lipopolysaccharide, produced by specific bacteria is responsible for inducing settlement and metamorphosis in larval marine tubeworms, Hydroides elegans - establishing biofouling.

NewsNovel method for synthesis of coral-derived compound offers hope for non-toxic fouling agents
Researchers have developed a novel total synthesis method for scabrolide F, a natural compound derived from corals, and revealed its antifouling properties.

NewsPreviously uncharacterized parasite uncovered in fish worldwide
Using genome reconstruction, scientists have unveiled a once ‘invisible’ fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level.

NewsNew study reveals that marine cyanobacteria can communicate using membrane nanotubes
Transfer of substances via membrane nanotubes not only occurs in cyanobacteria of the same lineage, but also between those of different genders, something that has been verified not only at the laboratory level, but also in natural ocean samples.

NewsWeaker ocean currents lead to decline in nutrients for North Atlantic ocean life during prehistoric climate change
Researchers at Georgia Institute of Technology have finished investigating how the prehistoric weakening of a major ocean current led to a decline in ocean nutrients and negative impacts on North Atlantic ocean life. The results support predictions about how our oceans might react to a changing climate — and what ...

NewsNew Rhizobia-diatom symbiosis discovery solves long-standing marine mystery
Scientists solve a longstanding marine mystery by uncovering a partnership between a diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean, with exciting implications also for agriculture.
-
NewsMarine bacteria team up to produce a vital vitamin
Researchers have conducted various experiments to analyse the interaction between two species of marine bacteria from the North Sea in the synthesis of vitamin B12.

NewsMarine microbial populations: Potential sensors of the global change in the ocean
A new study analyzes the knowledge generated to date on marine microbial populations and their role in the ecosystem, concluding that their analysis through space and time could reflect the effects of global change.

NewsMarine plankton behaviour could predict future marine extinctions, study finds
Marine communities migrated to Antarctica during the Earth’s warmest period in 66 million years long before a mass-extinction event.

NewsTropical coral-infecting parasites discovered in cold marine ecosystems
Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research from University of British Columbia botanists.

NewsMicroscopic sea urchin killer spreads to new species and regions
A parasite that devastated long-spined sea urchins in the Caribbean and Florida in 2022 has caused another die-off more than 7,000 miles away in the Sea of Oman.
