New paper out by my group and collaborators: Impacts of climate change on seaweeds, an editorial: www.frontiersin.org/journals/mar...

Still plenty of time to submit papers to the Annals of Botany special issue on #Macroalgae and #EcosystemServices. Deadline for submissions is Nov 30th! #Kelp #Fucoid #seaweed #CCA @annbot.bsky.social @pippajmoore.bsky.social @jebyrnes.bsky.social @twernberg.bsky.social @chrisecornwall.bsky.social

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 🌊 🧪

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...

So excited to be apart of The Ocean in a High CO2 World international symposium🪸 October 12-16, 2026! See you there!

Excited to announce that we will be hosting the 6th International Symposium on Oceans in a High CO2 World October 12 to 16th in Wellington at the Tākina event center! This conference will bring together marine climate change scientists from multiple disciplines. Save the date!

Our new paper in Journal of Phycology has come out today. Low light and low water motion can exacerbate the effects of marine heatwaves on giant kelp: onlinelibrary.wiley.com/doi/10.1111/...

If anyone is looking for regular updates on my group’s research or news, we are more frequently posting things on instagram. It’s not a perfect platform, but hey. Chrisecornwall is my handle, with my lab group updates and student work posted on coastal_eco_physio_group

See you all at the next #ITRS in #Tauranga, New Zealand 🇳🇿. Hosted by Chris Battersall, Chris Cornwall & Dave Schiel. Can’t wait to see you all there! @chrisecornwall.bsky.social @benthicecol.bsky.social @nessocon.bsky.social @katynicastro.bsky.social @pippajmoore.bsky.social @marclim-uk.bsky.social

Looking forward to it, see you all soon in Tauranga Aotearoa New Zealand 2028!!

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

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 😂

Check out some snaps from our recent MEDDLE workshop at #ITRS Brest, France on experimental design. Great participants! @scor-cobs.bsky.social

Check out our first Collection of articles we hope to publish in Ocean Ecosystems!

Can tropical corals find refuge at higher latitudes under future warming? In our new paper in Science Advances, we argue that coral range expansion will be *far too slow* for most coral species to outpace climate change. 🪸🌊 www.science.org/doi/10.1126/... A short 🧵 (1/16)

Ocean Ecosystems is calling for submissions to our collection on Ocean Ecosystem Services and Sustainable Development Goals, aiming to enhance our understanding of how to protect ocean health while ensuring the well-being of future generations www.biomedcentral.com/collections/...

Check out @ashtyn-isaak.bsky.social and her experiment at @seasim-aims.bsky.social along with other PhD student @hollykoch20.bsky.social ! Such an exciting collaboration and experiment! It explores how light and temperature related bleaching differs from the effects of ocean acidification

We just returned from a successful trip to Vancouver Island, exploring dissolved inorganic carbon use of seaweeds there. We collected more than 200 samples from over 40 species! Big help from the three students on the team (Denisa Berbece, Alessandra Walsh and Eloise Bennett)

Reminiscing on the fantastic conference put on by @aslo.org at the Aquatic Sciences Meeting in March 2025 in Charlotte, North Carolina I presented some of my results from two natural analogue sites; Semi-enclosed lagoon and a CO2 vent How do coralline algae survive in extreme environments?

3. Blocking in time, by Steeve Comeau and @chrisecornwall.bsky.social Learn how to estimate the effects of two drivers on a response when your experiment is ‘blocked’ i.e. experimental units grouped in time, often because it’s not feasible to do all at once. nzoac.nz/s/Blocking_i...

2. Analysing scenarios, by Steeve Comeau and @chrisecornwall.bsky.social Learn how to estimate the effects of two drivers on a response when your experimental treatments are designed to reflect future climate scenarios. nzoac.nz/s/Scenario_a...

We are hosting the 39th ASPAB meeting at Te Herenga Waka Victoria University of Wellington. 24th to 25th November. Please come if you are interested in seaweed!

🌊 @noaa.gov was a leader on ocean acidification (OA) and marine carbon dioxide removal (#mCDR). This research is decimated by the firings of many outstanding staff, including the leaders of the OA and mCDR groups, my close colleagues Sarah Cooley and Gabby Kitch. #StandUpForScience

Some good news today: 4 of my PhD students were successful recently in obtaining awards. Holly Koch, Imogen bunting, and Katie Whenton got SBS funding to go to ASLO or ITRS. But, bigger news: Denisa Berbece obtained a Coastal People Southern Skies Centre of Research Excellence PhD scholarship, yay!

This is possibly worse than Australian politicians getting involved in who gets grants. Just remove all social science funding completely… how is this allowed?

Hmm, watch this space. Might be bye bye for many NZ scientists to Aotearoa

Our next experiment’s army of coral frags ready to go. With 2 coral species and 2 CCA we will test physiological differences between thermal bleaching, light induced bleaching, and low pH induced bleaching using physiology, skeletal geochemistry, and gene expression at AIMS

As another #PhycologyFriday winds to a close, here's a starter pack of algal appreciators to follow! Lmk if you'd like to be added to the list. go.bsky.app/RwMphxS

This is teaching part of some of the material put together by @scor-cobs.bsky.social members. Should be good! We will also run one at ITRS in France too

Loss of Kelp forest in New Zealand and Australia is one of our less well known but critical climate change impacts from warming waters. Kelp forests are the coral reefs of the temperate and sub-polar oceans. www.abc.net.au/news/2024-11...

Every wondered where you can get good resources for marine climate change research, including papers, workshop events, video resources for training and teaching? Here is a working group devoted to that:

We've written papers/guides about how to improve experimental design so that we learn more from experiments. We also teach workshops and build tools based on these principles. 🌊 onlinelibrary.wiley.com/doi/10.1111/... www.sciencedirect.com/science/arti... www.annualreviews.org/content/jour...

Hello all! We're a working group studying how interacting drivers (or "multiple stressors") like temperature, acidification, etc. shape marine life. Follow us for new research and workshops, as well as tools to improve experimental design, data analysis, mathematical models, and more. 🌊

PhD student Katie Fenton discusses her PhD on the impacts of extreme events on pāua in Aotearoa New Zealand’s North Island. Talk at our Coastal Ecology Lab at Victoria University of Wellington

I see a lot of activity recently, so thought it was an ideal time to summarize who I am and what my research group does: We seek to better understand how kelp forest and coral reef ecosystems function, as well as their responses to local and global anthropogenic change. Check out some recent pics!

I hope everyone had or is having a good Valentine’s Day. If not, hopefully this coralline recruit grown in one of our experiments will cheer you up!
