Pleased to share our new publication in @aslo.org L&O! We used #radium-224 to quantify vertical mixing and benthic silicate fluxes across the #Baltic Sea. Read more here (fully open access): doi.org/10.1002/lno.... With (and others): @barefootlab.bsky.social @biogeoste.bsky.social

Radium isotopes quantify vertical mixing and reveal large benthic silicate fluxes in anoxic deep waters

Benthic fluxes are important sources of nutrients and dissolved carbon to the water column. Yet, most approaches for quantifying benthic fluxes are labor intensive and cover relatively small areas of...

Congrats @acabral.bsky.social on another awesome mangrove paper!

Alex Cabral@acabral.bsky.social · last yr.

🌿 Pristine mangroves absorb nitrous oxide (N2O), offsetting up to 71% of methane (CH4) emissions. 🌎 Global N2O uptake may compensate one-third of aquatic CH4 emissions. aslopubs.onlinelibrary.wiley.com/doi/full/10.... @aslo.org @barefootlab.bsky.social @biogeoste.bsky.social #ASLO_Letters

Large scale submarine groundwater discharge dominates nutrient inputs to China’s coast. Total SGD accounted for 19–54% of nutrient inputs, exceeding inputs from atmospheric deposition and rivers. www.nature.com/articles/s41...

New paper just published! We combined a water mass decomposition with biogeochemical tracers to untangle advective nutrient sources from the Gulf Stream and the Labrador Current versus local recycling along the Northwest Atlantic continental shelf.

A nice letter by Yau et al., looking at CO2, CH4 and N2O fluxes across the glacier-ocean continuum in Iceland 🌊 agupubs.onlinelibrary.wiley.com/doi/full/10....

My last PhD chapter is out! Combined GHG fluxes reveal a net carbon sink across a glacier-ocean continuum — glacier exports CH₄ to coastal waters, but strong CO₂ uptake outweighs GHG emissions. 🌊❄️ Read more: agupubs.onlinelibrary.wiley.com/doi/full/10....

Combined CH4, N2O, and CO2 Fluxes Reveal a Net Carbon Sink Across a Glacier‐Ocean Continuum

A rapidly-retreating marine-terminating glacier exported CH4 to nearshore waters N2O was undersaturated near the glacier front The regional CO2 sink greatly outweighs CH4 and N2O emissions
