Impacts of marine heatwaves on biodiversity and ecosystem services: our new paper in Nature Reviews Biodiversity is out! doi.org/10.1038/s443.... @natrevbiodiv.nature.com @uwaoceans.bsky.social @filbeek.bsky.social @dansmale1.bsky.social

NEW PAPER: We discovered some v old but v detailed kelp data in MBA archive (Mary Parke's surveys from the 1940s!! 🤯🤯) and resurveyed some 80 years later. Found that Laminaria hyperborea popns in SW England in decline, likely to due warming.... onlinelibrary.wiley.com/doi/10.1111/...

Yet again we are seeing "unprecedented" marine heatwaves in 2025. buff.ly/mnEcYcV What will we see in 2025 & beyond? @dansmale1.bsky.social comments, “If this continues through the summer we would expect to see widespread biological impacts. This is a significant warming event." buff.ly/U6iBTBN

So much life springing up in Plymouth Sound area at this time of year.... bloom is picking up, kelp is luscious, animals getting going: 5-6 m viz, 11 deg C, fair conditions. Great start to the summer diving season 🫡

So good to get the 2025 MBA Dive Season up and running! Despite recent torrential rain, viz was pretty decent and conditions were fair in Plymouth Sound. Training day and first surveys in the bag, great team effort 🌊🌱😎🤿🐟 @thembauk.bsky.social

Summertime marine heatwaves (MHWs) in 2023/2024 were unprecedented and had wide-ranging biological, physical and societal impacts. Need to develop better response plans and adaptation/intervention approaches as MHWs intensify under climate change. New ms in Nat CC: www.nature.com/articles/s41...

The rising intensity of #MarineHeatwaves is putting our ocean at risk 🌊🔥 A groundbreaking new study led by Dr Katie Smith, Postdoc Researcher at the MBA, reveals the summers of 2023-24 saw 3.5 times more marine heatwave days than ever recorded before. ➡️ buff.ly/3Qy8dLJ 📷 The Ocean Agency

Absolutely blown away and stunned by this news! Amazing to receive recognition from such a prestigious and historic organisation. Obvs this is not possible with out all the amazing students, ECRs and long term collaborators ive been fortunate to work with (eg www.marineheatwaves.org and kelp nerds)

New paper hot of the press for #phycologyfriday !!!! 🌱🌊🌞We conducted a warming experiment in the field to test stress responses of the intertidal habitat forming seaweed Fucus serratus: nsojournals.onlinelibrary.wiley.com/doi/10.1111/...

💯- send your amazing work to society journals like the ESA, BES, ASLO ones, new phytologist, JMBA, etc , much better for all concerned 😄

We conducted a 'classic' kelp canopy removal exp in mixed Laminaria forests in southwest UK. Results show that loss of canopy increases 5-fold the light reaching the reef which leads to 7-fold increase in understorey algae & 9-fold increase in kelp recruits; ms: www.sciencedirect.com/science/arti...

Just about to leave the office for 2.5 weeks 🎄🥳🎉. Nice evening for it. By my next visit the days will be getting longer 🥳🥳. Merry Christmas one and all 🎄 👊🥂🍻🍸

There's been some healthy debate about which baseline to use when quantifying marine heatwaves (and other extreme climatic events). We summarize the pros/cons, explain why it matters and provide some recommendations in our new ms: www.sciencedirect.com/science/arti...

Re-upping this PhD opportunity in marine ecology, applying a trait-based approach to seaweed carbon dynamics. Includes exciting opportunities for international fieldwork and open to applicants worldwide tinyurl.com/bdhs3aac

Intertidal seaweeds are more branched at low than high waves (opposite expected), maybe because the lack of water splash increases heat and desiccation stress (increasing breakage – and branching) in the intertidal (we did not find the difference in the subtidal). link.springer.com/article/10.1...

Marine heatwaves (MHWs) don’t just harm ecosystems—they also alter the ocean’s carbon cycle! Our new analysis of 30 global datasets shows ocean CO₂ uptake drops by 8% during MHWs, with regional anomalies reaching up to 30%. 🌊

🚨🚨🚨 Detailed demographic studies of marine foundation species are needed, especially at species' range edges, to understand responses to warming and other changes. In our new ms we quantified popn structure of Laminaria ochroleuca at leading range edge in SW UK. www.tandfonline.com/doi/full/10.... 🌿

What is the best way to define a baseline for marine heatwave (MHW) research – or extreme events in general? A new study from a wide range of experts highlights that the choice of baseline matters and should be tailored to the specific application. www.sciencedirect.com/science/arti...

is #phycologyfriday a thing on here yet? Maybe it is, maybe it isn't. Either way here is a pic of the golden kelp Laminaria ochroleuca, taken at 12 m depth on a reef near Plymouth Sound, UK. This species is warm-adapted and proliferating in some sites following recent ocean warming 🌱☀️🌊

Pretty decent few days of views from the office window 🤩🤩🤩 Plymouth Sound looking dazzling from the MBA this week....

Interesting time of year or UK kelp forests as kelp have stopped growing and are getting 'fouled' by lots of epibionts (mostly bryozoans and algae), the red algae on reef and kelp has largely senesced, & much detritus has washed out or degraded leaving a spooky 'clean' vibe before winter storms.

On 'the other place' I regularly posted about marine heatwaves (MHWs) which can have massive ecosystem impacts. The current MHW off Japan is incredibly long-lasting (>2 years!!?!) but showing some signs of decay now. Will impact on fisheries, coastal habitats and biogeochem processes for sure.
