Article: Coastal seaweed transported to the open ocean contributes ~3-4% of the particulate organic carbon sinking into the deeper ocean

Global #seaweed forests export 56 million tonnes of carbon (15% of their production) to the deep ocean annually. These biodiverse #blueforests are overlooked in the global ocean #carbon budget. We provide national estimates of this C #sink https://t.co/GB4m7UYUnz @NatureGeosci

How effective are #MPAs for conserving #kelp #forests? Our perspective shows they can help with some drivers of loss like grazing, but often fail to protect against ocean warming and coastal darkening - 2 main reasons we are losing kelp forests globally! https://t.co/arCzLYq5Ft

I am pleased to share our Perspective article in @PNASNews exploring photosynthetic production occurring on the elusive Arctic seafloor.

Happy to share my first PhD publication in @AnnBot. We found that detrital photosynthesis is a key determinant of #kelp detrital dynamics and is more sensitive to elevated temperature than expected: https://t.co/VJcm2UohQB. @BiolSci_UWA @UWAOceans @ForrestResearch

Underwater rivers export up to 50% of #kelp #carbon from shallow reefs to deep ocean, with potential for #sequestration. Our new paper shows dense shelf water transport is a major mechanism for kelp export off Australia's #GreatSouthernReef and elsewhere! https://t.co/Jp2UxE13H0

So great to see some #kelp forest recovery out of Nova Scotia! https://t.co/iPsUKiEw8A
🥰 nice work by @krumkir

[Jurgen Valckenaere @JurgenValckena1]

Haven’t heard about #kelp? No surprise… despite covering 1/3 of the world coastlines, they remain practically absent in international governance. Check our Policy Brief in @FrontiersIn with @Filbeek @twernberg & E. Techera

We just held our 5th workshop, this time in Majorca 🇪🇸 , which focused on refining MHW definitions, adapting the approach to coastal/polar regions, and examining ecological impacts across taxa and ecosystems. Very fruitful discussions and exciting work to come.... 📈🌊🤓🌱🌞📉

@bosch_nestor @ECOAQUA_ULPGC @ulpgcresearch massive congrats Nestor!!! 🤩🤩

[D Smale @DanSmale1]

Our new piece in @Nature warns of likely marine heatwave intensification under the current/developing El Nino. Clear & urgent need to plan, monitor, manage and adapt to extreme ocean temperatures to reduce ecological and socioeconomic impacts.. https://t.co/1mHxHZ8WRM

@Unpop_Science @carlosduartephd @guitarfishmasum @pessa_3 @twernberg @NBFNetwork @DanSmale1 @Dortekrause @kasper_hancke @UWAresearch @Havforskningen Exactly! And another key difference between seaweed forests and old growth forests on land is that seaweed forests typically replace their entire biomass every year. So ‘old growth’ seaweed forests are growing a lot ☺️ 🌱

[Karen Filbee-Dexter @Filbeek]

Seaweed forests are carbon sinks! Our comment has finally been released outlining flaws in Gallagher et al's claim they are carbon sources. Their study confuses #bluecarbon research and creates doubt around initiatives to protect & restore #seaweedforests! https://t.co/Cfc090KuOe

[Albert Pessarrodona @pessa_3]

Seaweed forests fix large amounts of carbon. Much debate exists however on whether some of that carbon ends up sequestered, and sequestration can lead to tangible climate change mitigation. We synthesized the literature to figure this out... 🧵https://t.co/I5MvGPtKkm

4. Antarctica, which is currently in the dead of winter, has unexpectedly failed to reform it's winter sea ice this year.

This is an exceptional deviation from the norm that has left even the most orthodox scientists dumbfounded.
