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

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. www.science.org/doi/full/10....

Groundwater releases CO2 to diverse global coastal ecosystems

Groundwater is a hidden, steady source of CO2 to coastal waters.

N2O data over 6 fjords spanning from Sweden, Iceland to Greenland is out! Check this : agupubs.onlinelibrary.wiley.com/doi/full/10....

Global Fjords as Minor Sources of Nitrous Oxide to the Atmosphere

Nitrous oxide concentrations are highly variable among six North Atlantic fjords Temperate and Subarctic fjords are net sources, while the Arctic fjord is a net sink of N2O Fjords emit less N2O ...

Paper out @agu.org! Overall, global fjords are minor sources of #N2O to the atmosphere ❗ BUT fjords with #aquaculture and #anoxia host relatively high nitrous oxide #emissions 👉 doi.org/10.1029/2024... 🤝Great collaboration with @barefootlab.bsky.social @awahlin.bsky.social
