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

It's important for western scientists to approach collaborations as partners, not advisors. A common critique I hear from Indian & Chinese colleagues is they are shown agendas about how they should do things nationally which they weren't consulted on #AcademicChatter www.nature.com/articles/s41...

Nice weekend trip to Daya Bay field station with SUSTech undergraduates learning about coastal biogeochemistry, ecology and a mandatory photo opportunity with Nemo et al., 😅 🌊

Today, I chatted with a disheartened postdoc about a proposal rejection. One crucial message is that luck plays a role in review comments. You can submit the same proposal 3 times and get feedback that ranges from harsh to glowing. Nevertheless, I've noticed a few common criticisms to try and avoid:

🌊 The Arctic is melting fast. A cargo ship just sailed from China to the UK via the Arctic for the first time, taking half the usual time. Of course, what looks like a shortcut is really a warning: climate change is redrawing our planet’s map. observer.co.uk/news/nationa...

Subglacial freshwater from beneath the Antarctic Ice Sheet flows into the ocean under ice shelves. Vaňková et al., probe how this affects ice melt, finding that discharge impacts melt rates primarily via continental shelf temperature modification 🐧 🌊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

100 years of September sea surface temperature departures through this year. Check out how quickly some of the midlatitudes are warming! 🌊 Data from NOAA ERSSTv5 at doi.org/10.7289/V5T7...

Many of my western colleagues wonder why I choose to work in China, often from a hesitant perspective focused on cultural differences. A student's parents shared a beautiful perspective visiting our residential fieldwork yesterday: 'Better to be a stone on the bridge than a stone in the wall.' 🌍✨

100 years ago, research vessel #Meteor set sail to explore the Atlantic Ocean – one of the most important expeditions of the 20th century. To mark the anniversary, GEOMAR and DSM/Leibniz-Institut für Maritime Geschichte launched a storymap. 🔗 storymaps.arcgis.com/stories/5712...

I visited the very beautiful New Yuan Ming Yuan in Zhuhai (Guangdong, China) this week. The palace gardens are said to have been inspired by the Old Summer Palace in Beijing which was looted and burned to the ground by some very bad people from a very bad country 😵😵😵 in 1860

Happy #FieldworkFriday from our SUSTech students who are busy in Dapeng running large-scale incubations to look at the side-effects of Ocean Alkalinity Enhancement on marine ecosystems 🌊

One of my staff asked an interesting question today; to what extent companies can #patent the ideas behind 'negative emission technologies'. Their reason for asking was a company filing a patent that covers many aspects of the use of ocean alkalinity enhancement for sequestering CO2.

I think this is my favorite ever typo 🍾 Alas, there is usually too little champagne in the field, and too much work 🌊

Happy Friday afternoon folks. Here be some leaf sheep wishing you a lovely day 🌊

My old office mate from my PhD says talking about her career changes in geology. A bit of a common theme as I talked at our schools industry and career night last night. My career definitely wasn’t straight - MSc, Consulting in industry, PhD, Government research agencies, 5 years ago academia. 🌊🔬👩🏼‍🔬

ClimatePulse has been updated! Still with @copernicusecmwf.bsky.social #ERA5 and two days behind real time. New layout, with better maps, easier to display different regions and compare different years data. Let us know if you have feedback for future updates 🌏🌊⚒️🧪🌡️ Check it out 👇

Freedom of speech: In the US & UK it's ok to say "I support the murder of 20,000 kids, starvation as a weapon of war against 2 million in #Gaza and an apartheid state" But it's illegal to boycott Israel for crimes against humanity or support Palestine Action. english.palinfo.com/news/2025/09...

Do you ever feel like somebody's watching you? This goosefish — with a wide, flat head, gaping mouth, and an abundance of patience — belongs to the family Lophiidae, which are ray-finned fishes belonging to the order Lophiiformes, the anglerfishes. #uruguaysub200

Underwater barriers might slow warm currents from melting Greenland’s glaciers, but not without hurting fisheries, @markinchina.bsky.social and colleagues point out in a recent commentary. eos.org/research-spo...

The UK is arresting Palestine supporters for holding signs under terror legislation. This is an appalling violation of civil rights. How can @ukparliament.parliament.uk allow this? Meanwhile Israel acts with impunity, protected by the west as it murders, starves and abuses civilians #FreePalestine

"Negative CO2 emissions" became a hot topic in oceanography. Yet there are many concerns about potential side-effects of trying to manipulate the C cycle. With partners from across Guangdong & Hong Kong we've developed a coastal site to investigate side-effects of Ocean Alkalinity Enhancement 🌊 🐠

New paper in Nature Climate Change, with Peter Landschützer of VLIZ. The ocean carbon sink is ailing: during the record 2023 marine heatwave, the ocean absorbed ~1 Gt less CO₂ ≈ half of the EU’s annual emissions www.vliz.be/en/news/ocea...

Just finished a LEGO build Shackleton’s Endurance. The discovery of the 1915 wreck in the Antarctic in 2022, was only a few months before Victor Vescovo took me to Challenger Deep in the W.

A disaster for ocean and climate research is unfolding before our eyes. #NOAA 🌊 "The White House Office of Management and Budget is pulling back $239 million in funds Congress already provided. The biggest hits fall on climate and ocean research." oceanpolicy.substack.com/p/roundup-un...

Meltwater strongly perturbs the carbonate system in the ocean. Henson et al., use new data from Greenland to show that, as well as driving an inorganic CO2 sink, the diluting influence of meltwater on alkalinity weakens the buffering capacity of these regions 🌊 www.nature.com/articles/s43...

Greenland's fjords are the gateways via which the ice sheet interacts with the open ocean. A large fraction of all the ice calved from the ice sheet melts within these regions. Kinne et al., explore how all this melt affects fjord circulation 🌊 🐻‍❄️ agupubs.onlinelibrary.wiley.com/doi/10.1029/...

There was a hint in 2024 that China's Carbon emissions had peaked due to their massive roll out of renewables, which continues. Now the data from the first half of 2025 confirms that CO2 emissions in China are decreasing. 🧪🔌💡☀️💨🌊🔋

Many western scientific networks are overly centered on the US. In previous decades it could be claimed that this was because the US represented a Gold Standard in scientific research. But the world has changed, and this is no longer the case. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Are technological fixes to climate change better 'solutions' than doing nothing? This narrow framing ignores complex ecological risks & the undermining of climate action. A more realistic framing is that geoengineering 'solutions' at best partially mitigate one problem by creating more risks 🌊 🐳 🧊

At high school, our English teacher challenged us to make a new word and get it used. Unfortunately, my homework is late; overdue by 22 years. But happy to submit my effort in print today: "Geoengineeringization" - the increasing popularization of geoengineering as a topic of scientific research

This photo of a humpback whale entangled in fishing gear*. 🥺 It's shameful that the global plastic pollution treaty went nowhere. *from Oceanographic Magazine's Ocean Photographer of the Year competition. 🌊 www.theatlantic.com/photography/...

"Understanding the oceans' role in climate really boils down to describing the expansion or contraction of the major carbon reservoirs" Timely reminder that gross & net flux estimates need to be clearly distinguished when discussing "carbon sequestration".
