Carbon dioxide, methane and nitrous oxide cycling from the coast to the deep ocean

Session ID#: 253639

Session Description:
The ocean plays a major role in global budgets of carbon dioxide, methane and nitrous oxide, but challenges remain to resolve production and consumption pathways and quantify fluxes across diverse marine habitats. Generally, marine biogeochemists either work on the coast with growing focus on blue carbon ecosystems, or focus on the “deeper” zone including marginal seas, fjords, and the open ocean. Although marine habitats are incredibly diverse, they share specific environmental properties such as oxygen and salinity gradients, interactions with sediments, and turbulence at the sea-air interface. To measure current fluxes and predict future fluxes of greenhouse gases affecting climate, it is imperative to understand production and consumption mechanisms in diverse oceanic ecosystems. We encourage submissions that will improve our understanding of both basic and applied concepts related to oceanic greenhouse gas cycling, fluxes, and budgets. We aim at a multidisciplinary session combining expertise in biogeochemistry, microbiology, geophysics and modelling. Investigations linking marine greenhouse gas dynamics to the triple planetary crisis (climate change, biodiversity loss, and pollution) are particularly welcome. This includes explorations of how deoxygenation, ocean acidification, and global heating impact greenhouse gas sources and sinks.
