Long-term nitrogen burial exceeds denitrification in global fjords - Nature Communications Contrary to previous assumptions, nitrogen burial – not denitrification – dominates nitrogen loss in fjords, accounting for up to 18% of oceanic nitrogen burial. Deoxygenation may yet alter the future...

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...

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.

The 2nd PhD paper by @hlscheung.bsky.social with a great team @barefootlab.bsky.social, etc. is out now in @jgrbiogeo.bsky.social @agu.org

🌿 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.

New online! Biogeochemical consequences of marine fisheries and aquaculture

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

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. 🌊❄️

Overall, global fjords are minor sources of #N2O to the atmosphere

❗ BUT fjords with #aquaculture and #anoxia host relatively high nitrous oxide #emissions

Groundwater releases CO2 to diverse global coastal ecosystems Groundwater is a hidden, steady source of CO2 to coastal waters.

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.
