Data from Ocean Sampling Day has been released! Ocean Sampling Day (OSD) is a simultaneous worldwide research campaign where marine biologists around the globe participate in sampling of the world’s oceans to produce contextual genomic data contextual genomic data. The data include 16S, 18S rRNA, and metagenomics data as well as environmental measurements made during the sampling events at each sampling site.

230 pilot whales stranded on a beach in Tasmania, Australia. Despite rescue efforts, sadly, 204 of the whales died.
Skinny salmon makes for skinny orca. New research suggests the southern resident killer whale population are suffering not just because chinook salmon numbers are very low, but because the salmon they’re finding just aren’t big enough to give the orca the energy they need.
Who has a favourite arm? Why octopus of course! Researchers discovered California two-spot octopus favour their second arm from the middle for hunting prey. Whether they use the arm on the left or right, depends where the prey is located.

It’s not just human bodies that are influenced by exersize. Researchers find sea anemone ‘exercise’ changes their developing size and shape.
Climate Crisis
Rising sea temperatures are making Bulwer’s petrels vulnerable, thanks to changes in their prey.
Not great news from the Arabian Gulf. Researchers have found an expanding and intensifying low-oxygen zone.
When trying to predict the damage tropical cyclones will do to coral reefs, using climate models may not give the most accurate information.
Copepods may be able to adapt to warmer and more acidic waters, as long as other stress factors don’t come on top.
Over the past fifty years, the ocean has absorbed 90% of the excess heat caused by carbon emissions, with the Southern Ocean doing most of the heavy lifting.
In a bid to protect British Columbia, Canada's kelp forests, researchers have developed a cryogenic freezing technique to store germplasm, or “seed”, of at-risk bull kelp in a biobank.
Fisheries and Aquaculture
Non-profit Monterey Bay Aquarium Seafood Watch have placed American lobsters on its Red List. The recommendation to avoid American lobsters comes down to the risk the lobster traps pose to North Atlantic right whales. The Maine lobster industry has already pushed back on the listing.
Scientists are supporting a ban on bottom trawling and other industrial extractive activities from the EU’s marine protected areas.
Never heard of cusk? You might do in the future. Researchers in Norway put this bycatch fish to the taste test. The results were rather favourable!
The EU Comission has closed 87 sensitive zones to all bottom gears in the EU waters of the North-East Atlanticin an effort to better protect vulnerable deep-sea ecosystems.
Scammers are ever-inventive with their scams, like a fake website claiming to sell USA federal and state fishing permits.
Fisheries and Oceans Canada want to buy back British Columbia salmon fishing licencesin the hope of protecting stocks.
Indigenous lobster divers in Honduras have suffered debilitating medical conditions from their deep-water forays without proper equipment or protocols. Back in 2021, 42 members of the Miskito community successfully sued the Honduran government over their failure to regulate, supervise and oversee the deep diving lobster fishing industry sued the Honduran government over their failure to regulate, supervise and oversee the deep diving lobster fishing industry. They’re still waiting for compensation.
Chinese soldiers have been driving away fishing vessels from waters around Mischief Reef, an area that China, the Philippines, Taiwan, and Vietnam all claim to be theirs.
In response to historically low levels of sardines, the South African Government has declared temporary closures for commercial fishing of anchovies and sardines around major penguin colonies.
In efforts to tackle seafood fraud, researchers are building a database of “chemical fingerprints common to the bones and shells of marine life from specific ocean environments.”These fingerprings will help udentufy where seafood really comes from.
Faced with an unexpectedly large catch, one fishing boat dumped some 900,000 menhaden off the coast of Louisiana, USA. Unsurprisingly, the action, and catch size, has drawn ire.
Marine Technology
CalWave is pressing ahead with its plans for wave energy. The company has completed its ten-month-long open-ocean wave energy pilot off the coast of San Diego.
Nanosatellite, Seahawk-1 CubeSat reached a new milestone in September when in transmitted it’s 5,000th high-resolution ocean colour image to NASA!

Researchers harness the power of dinoflagellates to create soft devices that glow in the darkwhen squished, stretched, twisted, or bent.
Fully biodegradable polyurethane foam? Researchers take a look at what happens to the foam in the ” the first commercially available biodegradable shoes” when they end up in the ocean. Apparently, ” an assortment of marine organisms colonizes on the polyurethane foam and biodegrades the material back to their starting chemicals, which are consumed as nutrients by these microorganisms.”
Could Brillouin scattering spectrum be the next big think for ocean lidar remote sensing technology? Research from China suggests it’s possible.
People and the Sea
The UK is continuing to dump raw sewage into the ocean. What went wrong? Outdated infrastructure, low investment, privatisations, and feeble fines, says Dr Edmonds-Brown.
