A More Sustainable Way to Attend Distant Science Conferences
For AGU’s annual meeting in 2023, a virtual hub in Zürich combined remote presentations and in-person viewing groups to reduce travel but keep in-person interactions.
Los microplásticos son el ingrediente no tan secreto de la nieve marina
Partículas diminutas de plástico degradadas y cubiertas por biopelículas se hunden hasta el fondo marino llevando consigo carbono.
Cuando los bosques en la tierra arden, los bosques submarinos sienten el impacto
El kelp es un hábitat, un sumidero de carbono y un agente aglomerante en tu helado. Pero estudios recientes muestran que los bosques de kelp en California son afectados por el destino de sus contrapartes sobre tierra.

The Unfair Share of Shade in California’s Central Valley
Researchers find that disadvantaged communities in Fresno are significantly sunnier and hotter than wealthier ones.
Microplastics Are the Not-So-Secret Ingredient in Marine Snow
Particles of tiny, degraded plastics coated with biofilms sink to the seafloor, carrying carbon with them.
Steamy Bubbles May Control Old Faithful’s Clock
Scientists built a minigeyser to show why the natural wonder’s water surges so violently between eruptions.
When Forests on Land Burn, Forests Underwater Feel the Impact
Kelp is a habitat, a carbon sink, and a binding agent in your ice cream. But new research shows that California’s kelp forests are affected by the fate of their counterparts on land.
