My Christmas present this year. A painting of the RV Tangaroa in the Ross Sea Antarctica by Alfred Memelink memelink.nz. Anyone have nice paintings or artwork of research vessels in beautiful places? 🌊🚢 please share.

It may not be a holiday in China, but the research group went for "traditional" KTV (Karaoke) after dinner anyway 🎄🎅🎁

Finished -what I hope😅- is my last #peerreview for 2025 The number I get asked to do keeps going up. In 2025 I finished 30 reviews which is about as many as I can accept. Curiously, either I got kinder or Editors are sending me better drafts (or maybe both!)- only 3 recommended rejections this year

Getting students to fill in their end of course evaluations...🤔 A little cake moves things along much faster than weeks of badgering emails, from 29% to 96% completion in an hour 😆 #Academicchat

#OnThisDay in 1872, the expedition of HMS Challenger set sail from Portsmouth, travelling nearly 70,00 nautical miles and cataloguing over 4000 unknown species over 4 years. This pioneering expedition, organised by the Royal Society, laid the foundations of oceanography.

The Arctic is sparsely populated but still functions as a sink for a large amount of the Pb humans have released into the environment. Atlantic water doesn't only carry heat into the Arctic, but also Pb from European/American industry @geotraces.bsky.social 🌊 www.nature.com/articles/s41...

I'm not the most creative person 😅, but fortunately some of our students are and they made our working group a new logo and a fantastic webpage with all our projects and research areas 🐻‍❄️ 🐧 🐳 🌎 www.hopwood-marine-science.com

Greenland's fjords are pathways for exchange of heat and freshwater between the continental shelf and outlet glaciers of the Greenland Ice Sheet. Vries et al., present year-round water column velocity observations for Nuup Kangerlua in SW Greenland 🌊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

It's well known meltwater has some peculiar effects in the ocean, but we're always happy to find a few more! Ambient conditions are very different in Greenland & Antarctica, but curiously in both cases we see short-term negative responses of plankton to meltwater 🌊 online.ucpress.edu/elementa/art...

Fun day poking around with a bunch of weedy sea dragons. Lucky me! #WeedySeaDragon #MarineLife #UnderwaterPhotography #PortseaPier

Some of Nicolas Horniblow’s most profound experiences happen on night dives. Once the light drops, the reef shifts. Species that hide during the day move out, and the whole community runs on a different rhythm. greatsouthernreef.com/nicolas-horn...

Publication fees are a drain of scientific resources, but individual scientists can't change the system. "Funding agencies hold all the cards". They can and should mandate change; set reasonable terms and ensure good value for public money. www.researchprofessionalnews.com/rr-news-uk-o....

River alkalinity is critical for coastal carbon dynamics & marine ecosystems. According to a modeling study, it significantly reduces the air-to-sea CO2 flux in river-dominated coastal ocean, and therefore OA (i.e., ~70% less flux into the ocean): 🌊🧪 agupubs.onlinelibrary.wiley.com/doi/full/10....

A rather pointed Opinion piece in Frontiers & a totally bizarre situation. Nature Geoscience published a 2024 claim of dark O2 production on the Pacific seafloor. There were several obvious problems with the work & multiple lines of argument that it wasn't correct www.frontiersin.org/journals/mar...

Top marks @klaus-tschira-stiftung.de for their review format. Of all organizations I review for, their procedure is by far the smoothest 👍 Many organizations that ask for peer reviews are not so careful, so I have a 15 minute rule- If I can't access files within 15 min of trying, I decline to do it

Do you have Dissolved organic carbon (DOC) and ColouredDOM/FluorescenceDOM data from coastal waters? Join this BioGeoSea initiative and help create a global, open-access dataset that will transform how we monitor coastal DOC and understand biogeochemical processes.

The "nutritional value" of glacial runoff is changing. Researchers found meltwater from retreating glaciers delivers sediment with lower concentrations of usable iron and manganese to coastal ecosystems. ❄️🧪 eos.org/articles/gla...

What's interesting as the Thanksgiving Holiday arrives? The first @bgc-argo.bsky.social profiling floats begin to emerge from under Antarctic sea ice each year. Float 5905383 is the first @soccomproject.bsky.social float for 2025/26. It has spent 7.9 years operating under ice. #argofloats #oneargo

Unfortunately the west is often in a state of denial to colonial injustices which continue to this day. Greenlandic parents in Denmark are 6x more likely to have their kids taken away. Why? Maybe because tests to determine a fit parent are based on Danish cultural norms www.bbc.com/news/article...

We've known burning fossil fuels causes global warming since 1911. We've known the quantitative relationship between increasing atmospheric CO2 and global warming since 1977. But in 2025 we still cannot achieve a global political consensus on how & when to stop burning fossil fuels 😔 #climatechange

Can you see the scorpionfish? (hint: eyes to the left, caudal fin to the right) They are tremendously camouflaged and I generally miss them, but this one shot in front of me, dropped onto some coral, and then stayed motionless. 🦑 #scuba #diving #oceans

Use of citations and paper numbers as evaluation criteria for anything is not only flawed, but also widely abused, even in quality journals. Stats for my favorite, respected oceanography journal show the "top" 2 2022/23 papers were both outliers, by the same author, and self-cited 23+ times (!!!) 🌊

We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing: a 🧵 1/n Drain: arxiv.org/abs/2511.04820 Strain: direct.mit.edu/qss/article/... Oligopoly: direct.mit.edu/qss/article/...

Science fraud is on the rise, facilitated by for-profit, open-access journals (Richardson et al, 2025, PNAS). These same journals are accelerating author and reviewer burnout by profiting from quantity while neglecting quality. Choose society journals where reputation and community are everything!

It always tickles me silly when I read some reviewer's blunt comments about a piece of submitted work being useless/worthless/meritless/unpublishable, without much of a constructive comment about why or how to improve, and the authors reply... "Thank you for this insightful/thoughtful comment" 😅

The domination of scientific publishing by major commercial publishers is damaging science... Amen to that. Journals should be led by public scientists Journals should be publicly owned & "Number of papers published" should mean nothing to anyone #AcadmicChatter

I've lived on the top floor before, but previously this was in the context of a bedroom in the attic 😅 The view over Shenzhen Bay and Hong Kong is slightly better this time 😆

In the latest Global Carbon Budget, the estimate of the ocean carbon sink was increased by 0.8 Gt of CO₂ due to methodological changes. Each mCDR deployment aims to remove a tiny fraction of that, so if people think we have the methodology to do proper MRV for mCDR right now, they're delusional. 🌊

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

Free t-shirts must rank close to free food in the hierarchy of student motivation 😆 Our lab releases its first clothing line featuring work from our oceanography field program in Daya Bay 🌊

A key theme in the State of The Cryosphere reports is the same every year. The only effective option to reduce the impacts, damage and cost of climate change is to cut greenhouse gas emissions as quickly as possible. The faster emissions fall, the lesser the damage. iccinet.org/statecryo25/

🌊 How do we collect sea ice to measure tor trace elements and isotopes? You need a big drill to collect the core and then a lot of patience to shave down the outsides with a ceramic blade…to get clean ice to melt and analyze. Dr. Tia Anderlini on the trigger here.

I've unfortunately known colleagues who've died from preventable accidents, and colleagues who've sadly taken their own lives. Both issues need talking about regularly and openly. www.scmp.com/news/china/s...

Despite having a baby this year, perhaps surprisingly, my household's CO2 footprint is the lowest it's ever been 😅 I calculate this yearly for my undergraduate course. I haven't flown in 14 months and my wife has more than halved her business trips, so our footprint has dropped 🌎 #Flyingless
