Excited to share our new paper out today in Science led by Patrizia Ziveri and the BIOCAL Working Group! With @willerstorfi.bsky.social, @nanophyto.bsky.social, @tdegaridel.bsky.social and many colleagues! @climatecerege.bsky.social @icta-uab.bsky.social 🔗 science.org/doi/10.1126/science.adq8520

Calcifying plankton: From biomineralization to global change

The cycling of calcium carbonate (CaCO3) in the ocean is closely linked to seawater alkalinity and the regulation of atmospheric CO2. In the modern pelagic ocean, almost all CaCO3 is produced by three...

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social 🌊 www.science.org/doi/10.1126/...

Persistent eastern equatorial Pacific Ocean upwelling since the warm Pliocene

Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

Governing novel climate interventions in rapidly changing oceans

Marine systems are rapidly changing in response to global heating. The scale and intensity of change are triggering a host of novel interventions to sustain oceans and ocean-dependent societies. Howev...

An Israeli startup says its new technology will save the planet. Scientists have doubts. My latest piece looks at the company that bills itself as a frontrunner of the carbon credit industry, and the special, secretive particles it plans to unleash in the ocean. apnews.com/article/clim...

An Israeli startup says its new technology will save the planet. Scientists have doubts

A startup called Gigablue claims to have reached a milestone by selling 200,000 carbon credits for its ocean-based carbon capture technology.

AOML would close. However, Argo and the global drifter program would be transferred to the National Ocean Service, which is getting a $36 M bump for "Sustained Ocean Observations and Monitoring". Operational measurement programs are one of few parts of OAR that are being preserved.

France : vers une flotte océanographique écoresponsable

Par TV5MONDE NICOLAS GEORGE TV5 JWPlayer Field Mieux connaitre les Océans, leur faune et leur flore, c'est l'une des missions de la Flotte Océanographique Française. Mais voilà, cette flotte fait sa révolution. Son directeur, Olivier Lefort a ammarré son vaisseau Thalassa dans le porte de Nice. Il nous présente son programme pour améliorer et métamorphoser ces embarcations.
