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...

Nitrate‐Driven Eutrophication Supports High Nitrous Oxide Production and Emission in Coastal Lagoons
Eutrophication stimulates nitrous oxide emissions in coastal lagoons Excess nitrate induces incomplete denitrification, leading to high nitrous oxide effluxes in sediments Nitrous oxide emission...

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. Have a look: 👇🌊🧪 #AGU

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. 🌊❄️

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

The main DEI page from @agu.org has been modified to take diversity out of the title. Glad to see it's not deleted entirely, but hey AGU, we're watching what you do and remembering the big game you once talked about supporting your diverse membership.

Awesome outcome of Apra Tomer’s MSc work summarising >10 years of field investigations at 40 coastal systems from 14 countries.
Groundwater discharge explained much of the CO2 tidal dynamics in nearshore waters.
