Call for abstracts is open for the 6th International Symposium of the Ocean in a High CO2 World! We are looking for work that examined the impacts of ocean acidification, deoxygenation, mCDR, and multiple drivers of change: highco2-vi.org/call-for-abs...

Does anyone have any JCP standard for coral geochemistry? I’ve reached out to most of my local contacts and we are starting to hit a wall! Please flick me a DM if you do. We only need a little bit and can repay the favour somehow

The future remains bleak for corals – but not all reefs are doomed Coral reefs are likely to erode even under low-emission scenarios, but some reefs may persist if corals evolve to become more resistant to ocean warming.

We describe the potential impacts of climate change on coral reef growth in our new article in The Conversation theconversation.com/the-future-r...

New paper out yesterday by us and a large group of collaborators in Nature Reviews Earth and Environment. We discuss the persistence of coral reef structures under climate change. We highlight several possible futures for coral reef carbonate production: www.nature.com/articles/s43...

Beyond the beaches, Wellington’s catastrophic sewage spill could be bad news for coastal ecosystems Sewage spills are often seen as short-term public health crises. But the ecological impacts can be lasting, especially if combined with marine heatwaves and storms.

Wellington sewage outflow could kill marine reserve's kelp forest ecosystem A marine biologist says the worst case scenario if untreated sewage continues to be dumped in Wellington could be the die-off of the kelp forest ecosystem.

Pretty sad to see this occurring of our awesome coastline

Check out our new paper exploring how giant kelp (Macrocystis pyrifera) sporophytes from populations across Aotearoa New Zealand respond to marine heatwaves in simulated experiments. We find general similar sensitivities that tend towards similar thermal tolerances across large geographic areas.

Introducing Ocean Ecosystems - Ocean Ecosystems Introducing Ocean Ecosystems Our ocean ecosystems are of immense ecological, climatic, and economic importance. Yet, the ecological functioning and diversity of these ecosystems remain largely unexplored. Historically, much greater effort has been placed in publishing research on terrestrial and freshwater ecosystems compared to the marine environment [ 1], and the importance of processes within these systems is considered comparatively overlooked by other disciplines [ 2].

Date and time: 9:00–15:30, Sunday, February 8, 2026 Location: University of Glasgow, room details TBA Title of the event: Designing multiple driver experiments Conveners: Sinéad Collins, University of Edinburgh, Simin Gao, University of Edinburgh, Paul Renaud, Akvaplan-niva Description: The MEDDLE resources were developed to help researchers design and carry out tractable and comparable multiple driver experiments. In this workshop, participants will learn how to use these resources to design multiple driver experiments. While the concepts and methods discussed can apply to many systems, examples used during the workshop will focus on manipulative experiments rather than observational data. The workshop is geared mainly towards PhD students, postdocs, and ECRs new to multiple driver research, and focuses heavily on the rationale of different experimental designs, and analysis strategies for multiple driver experiments. A basic working knowledge of statistics is needed (regression analysis), and statistical analysis examples will use R. Participants should bring a laptop with R and R studio installed. Topics include: • Defining a research question • Identifying relevant drivers • Identifying biological traits and responses • Experimental designs for multiple driver experiments • Statistical analysis plans Hosted by the SCOR project “Changing Ocean Biological Systems”, this free workshop will be led by Sinéad Collins, University of Edinburgh (UK), Simin Gao, University of Edinburgh (UK), Paul Renaud, Akvaplan-niva (Norway). Spaces are limited. If you would like to attend, contact Sinéad Collins (s.collins@ed.ac.uk) by January 15, 2026 to register your interest. Limited to 24 people, so please register early! Please include a brief (<150 words) statement outlining (a) your experience carrying out Ocean acidification or multiple driver experiments (if any) and (b) how you plan to incorporate multiple driver experiments into your work

The COBS working group is offering an experimental design workshop before Ocean Sciences in Glasgow in Feb 2026! 🌊

Join us for a day of learning about designing and analysing multiple stressor experiments without getting multiply stressed out.

This is figure 2, which shows reef accretion potential across western Atlantic reefs.

Over 70% of coral reefs in the tropical western Atlantic Ocean are projected to be in a state of erosion by 2040, increasing to nearly all reefs in 2100 if warming exceeds 2 °C above preindustrial levels, a study in Nature suggests. go.nature.com/48m9Y8F 🌊 🧪

ps, paper led by Professor Chris Perry. Congrats Chris.

Reduced Atlantic reef growth past 2 °C warming amplifies sea-level impacts - Nature An analysis of coral reefs in the tropical western Atlantic suggests that nearly all will be eroding by 2100 if global warming exceeds 2 °C, which will worsen the effects of sea-level rise.

Our paper out today in @nature.com describes a grim fate for coral reef growth under climate change in the Western Atlantic. We also estimate that reef restoration could offer pockets of local hope, but overall cannot keep up with the effects of climate change www.nature.com/articles/s41...

Yes, definitely. We have an ECR committee who will help us ensure this is an ECR/student friendly conference

Same here, loved catching up with friends! Now on to ITRS 2028 in Tauranga!

Thanks Trine, good to hear you liked the workshop!

Thanks for arranging this #ITRS2025 workshop 🤩 It was a very useful exercise, and I loved going through all the steps of planning our perfect will-never-ever-get-funded project 😂 and to make our priorities when reality (i.e. huge funding cuts) were thrown at us 😂
