How CO2 Gets Into the Ocean

Our oceans absorb large amounts of atmospheric carbon dioxide. Liquid water is quite good at dissolving carbon dioxide gas, which is why we have seltzer, beer, sodas, and other carbonated drinks. The larger the surface area between the atmosphere and the ocean, the more quickly carbon dioxide gets dissolved. So breaking waves — which trap lots of bubbles — are a major factor in this carbon exchange.

This video shows off numerical simulations exploring how breaking waves and bubbly turbulence affect carbon getting into the ocean. The visualizations are gorgeous, and you can follow the problem from the large-scale (breaking waves) all the way down to the smallest scales (bubbles coalescing). (Video and image credit: S. Pirozzoli et al.)

Last week at the #AGU24 Fall Meeting in DC, our colleague David Gampe presented his research on the impact of snow droughts on the #CarbonCycle. These low-snow events hinder plant growth & carbon uptake through photosynthesis.

David & team analyzed 1982-2016 data to show how snow droughts are increasing GPP extremes, with hotspots in Central North America, Eastern Europe, & Eastern China. Huge thanks to #AGU for hosting & to all for the enriching conversations!

What happens to the world if #forests stop absorbing #carbon? Ask #Finland

Natural sinks of forests and #peat were key to Finland’s ambitious target to be #CarbonNeutral by 2035. But now, the land has started emitting more #GreenhouseGases than it stores

: Trees and land absorbed almost no CO2 last year. Is nature’s #CarbonSink failing?

Diatom surprise could rewrite the global #carbonCycle

eurekalert.org/news-releases/1

EurekAlert!Diatom surprise could rewrite the global carbon cycleWhen it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths of the ocean. These new findings from a team led by UC San Diego researchers could lead to reduced estimates regarding how much carbon dioxide diatoms pull out of the air via photosynthesis, which in turn, could alter our understanding of the global carbon cycle, which is especially relevant given the changing climate.
