Distribution of coastal blue carbon habitats in Sweden and their exposure to anthropogenic pressure - Ambio Understanding where blue carbon habitats occur and how they are affected by human activity contributes to effective management of natural carbon sinks. Here, we compiled geographical data for Sweden t...

New paper led by Sara Braun published in @ambio-journal.bsky.social. We mapped classic blue carbon habitats (seagrass & salt marshes) as well as emerging (coastal forests & rooted freshwater veg.) across the Swedish coastline. We found that blue carbon habitats cover 35% of the coast. rdcu.be/eS32n

Lack of increase in mercury contamination in coastal Western Australia since European settlement Current knowledge of long-term mercury (Hg) deposition is predominantly based on studies from the Northern Hemisphere, leading to a geographical bias …

New paper out today 🥳. We used a seagrass sediment record to reconstruct more than 3000 years of mercury contamination in Western Australia.

Se gäddan skrämma andra fiskar – kan öppna upp igenväxta vikar ”Skräckekologi” kan bromsa övergödningens effekter • Forskare undersöker fiskefredade vikar

Blir gäddor i fredningsområden mindre skygga, och hur påverkar detta isf ekosystemet i grunda havsvikar? Detta studerar doktorand Emil Kraft och masterstudent Alexander nu i sommar, vilket uppmärksammades av @svtnyheter.bsky.social : www.svt.se/nyheter/loka...

Global Patterns and Drivers of Seagrass Biomass, Net Primary Production and Meadow Structure Aim We decipher global patterns in seagrass growth and structure to advance seagrass science, facilitate multidisciplinary research, and promote effective management strategies and policy developmen...

The Executive Order “Restoring Gold Standard Science” is Dangerous for America This EO is an unconstitutional attempt to censor and punish U.S. scientists for publishing science that doesn't fit a political agenda This misleading and false misrepresentation of U.S. scientif...

"American science has no need to be "Restored" to a "Gold Standard:" American science has already set the "Gold Standard" for scientific research and publishing for over 80 years."

Global seagrass carbon stock variability and emissions from seagrass loss - Nature Communications Johannes Krause et al. synthesized seagrass carbon stock data from 2700+ soil cores to find that they vary by plant functional group and coastal setting, indicating where conservation efforts would mo...

A new global analysis reveals that if we allow seagrass decline to continue unchecked, as much as 1,154 Tg of Carbon Dioxide could be released back into the atmosphere from meadows at risk, accelerating the climate crisis we are trying to prevent.

New paper led by Johannes Krause out in @natcomms.nature.com. Here we assessed global seagrass carbon stocks and with new global median values being 27% lower than previous global estimates. We also estimated CO2 emissions following sesgrass loss. Read more 👉 www.nature.com/articles/s41...

Influence of landscape characteristics and submerged aquatic vegetation on sediment carbon and nitrogen storage in shallow brackish water habitats - Scientific Reports Scientific Reports - Influence of landscape characteristics and submerged aquatic vegetation on sediment carbon and nitrogen storage in shallow brackish water habitats

New paper led by Sofia Wikström @ostersjocentrum.bsky.social showed that coastal morphology is more important than vegetation for carbon and nitrogen storage in shallow coastal bays in the Baltic Sea www.nature.com/articles/s41...

Skyddade vikar är viktiga kolsänkor i Östersjön - Stockholms universitets Östersjöcentrum Havets kustzoner pekas ut som viktiga naturliga kolsänkor globalt, i synnerhet livsmiljöer med riklig växtlighet som sjögräsängar och mangroveområden. I bräckta kustmiljöer som Östersjön är kunskapen ...

Havets kustzoner pekas ut som viktiga naturliga kolsänkor globalt, särskilt områden med växtlighet som sjögräsängar och mangrove. I bräckta kustmiljöer vet vi desto mindre om kolinlagring, men en ny studie visar nu att även grunda, avsnörda Östersjövikar är betydande sänkor för både kol och näring.

Recommendations for strengthening blue carbon science Blue carbon (BC) habitats (e.g., mangroves, tidal marshes, and seagrasses) are important CO2 sinks but are among the most threatened ecosystems on Ear…

New paper out in @cp-oneearth.bsky.social. Here we reviewed common practices in blue carbon research and estimated uncertainties linked to different methods. We provide recommendations for 14 practices that can be improved to strenghten blue carbon science www.sciencedirect.com/science/arti...

Evaluating seagrass lipid biomarkers as indicator for organic carbon provenance and storage capacity in Zostera marina (L.) sediments Seagrass meadows are vital blue carbon habitats, with sedimentary organic carbon (OC) originating from both the seagrass itself and external sources. …

New paper out! We used lipid biomarkers to trace seagrass-derived organic carbon in eelgrass sediments and found a clear correlation between high carbon storage and seagrass presence. Read more here: www.sciencedirect.com/science/arti...
