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/...

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

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/...

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...

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:

🚨🚨🚨 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.... 🌿

Amazing to visit @tvarminne.bsky.social to act as opponent for a PhD defence by student of @alfnorkko.bsky.social and @joannanorkko.bsky.social - what a wonderful, historical marine station with some incredible science happening. Its proper Baltic ‘ere 🥶🌊❄️

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.

T'was a suitably cold n grey day yesterday for the final kelp survey dives of the field season. Very happy to get another year of in situ temp/light data and kelp habitat structure in the bag. Only possible with the dream team, 🙏🙏🙏. 🌊🌞🌱🤿📈🤓

The mind-blowing SST anomaly for the N Atlantic in 2023 continues, with sea temps still ~1.5 deg C above long term average and much of the central, NE and NW Atlantic remaining in a marine heatwave state. Pretty mental.....
