Ever heard of #IceSpec?

Kurbatov et al. explain how this new hyperspectral line-scan imaging system for ice cores can advance research on stratigraphic impurities, ice dynamics, and #paleoclimate.

📢 November news is out!

Did you know that PAGES has a monthly newsletter for the global #paleoscience community, featuring upcoming deadlines, opportunities, events, and other updates?

Catch up on everything in our latest newsletter: pastglobalchanges.org/news/138741

Abstract submission is open for #EGU26 (3 - 8 May 2026) 🚨

Are you working with #microfossils and have a story to tell about the #paleoenvironment and/or #paleoclimate? Then join our session to put a focus lens on these amazing micropaleontological proxies!

Cosmic dust reveals dynamic shifts in central Arctic sea-ice coverage over the past 30,000 years Arctic sea-ice loss affects biological productivity, sustenance in coastal communities, and geopolitics. Forecasting these impacts requires mechanistic understanding of how Arctic sea ice responds to ...

Huge paper for the Arctic Ocean published today in @science.org - a new 30,000 year history of Arctic Ocean sea-ice cover reconstructed from the accumulation of cosmic dust-derived helium-3! www.science.org/doi/10.1126/... (1/n)

Thank you Rehemat!! It is so nice to see you here 💛

Very proud to see our own @sofigerina.bsky.social shine! 🤩🌟💙

Thank you so much for this huge honor 💙🥲

Very grateful to be recognized by @pages-ipo.bsky.social & to my peers who thought of me for this award. It also fills me with purpose to see science communication + other outreach efforts don't go unnoticed. Science is for all! Muchas gracias @geolatinas.bsky.social @marumunibremen.bsky.social

🏆 Congratulations to Dr. Sofía Barragán-Montilla, recipient of the 2026 PAGES Early-Career Award (ECA)

Sofía uses tiny fossils, foraminifera, to uncover big stories about our oceans’ past. 🌊Thank you for your inspiring contributions to #paleoceanography

Forams are super cute, but some of them are just spooky 🎃Did you know some forams make their shells gluing “skeletons” of other fossils?

🤔 Did you know that with a weaker #AMOC tropical shallower waters got + oxygen in the last deglacial? 😱 Using benthic #forams, we explore how #AMOC influences Atlantic shallow circulation 🌊🐚🔬👩‍🚀 www.nature.com/articles/s41... @marumunibremen.bsky.social @natcomms.nature.com

How much do tides vary at your shoreline? The greatest variation can be found at the Bay of Fundy in North America where tide variation reaches 16 meters. It's a fascinating map to study. Have a look at the coastal areas that you are familiar with from your travels.

Hi again, Oxyguys!!🤓🌍🌊“Proxies: Windows into the Past” Did you know scientists can uncover past climates using proxies? These are measurable clues preserved in marine sediments—like tiny “time machines” recording signals of temperature, oxygen, or salt. @pages-ipo.bsky.social @pages-ecn.bsky.social

📑🔬¿Sabes qué es el oxígeno oscuro? Un estudio publicado en Nature Geoscience muestra un descubrimiento sorprendente: más oxígeno del esperado en el océano profundo. Aquí, el oxígeno proviene de la ventilación de aguas menos profundas y es consumido por organismos para respirar y oxidar materia.

📑🔬You asked about dark oxygen, here it is! In Nature Geosciences, a study shows a striking discovery: more oxygen than expected in the abyssal ocean. Here, oxygen is mostly supplied by ventilation from shallower waters, & it is consumed by organisms through respiration and oxidation of matter.
