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.

📣Exciting Announcement: PO2 Newsletter – 5th Edition is out! 🔬 🌊 🌏 We’re happy to share the new edition of the Past Ocean Oxygenation (PO2) Newsletter! This issue features updates on major events and recent research related to ocean oxygenation in the past. @pages-ipo.bsky.social

🎉Are you a mineralogist who also loves museums? 🎉 Come join the Natural History Museum Denmark! We are looking for an assistant professor and curator of mineralogy. Advert can be found below, but apply soon! Deadline is 11th August😱 candidate.hr-manager.net/ApplicationI...

🤔 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

🚨Our new @natcomms.nature.com paper is out! 🤔Did you know that with a weaker #AMOC, tropical shallower waters got + oxygen in the last deglacial?

📢The Past Ocean Oxygenation @pages-ipo.bsky.social Working Group is here! 🚤 We provide insights into the natural variability of seawater oxygen in key periods of the geological record & communicate the science behind oxygen reconstructions 🐳 PO2 is here! pastglobalchanges.org/science/wg/p...

Hi again!📝¿Oxígeno Disuelto en el Océano (OD)? 🌊🤓¿Sabes qué es? Hablemos de algunos conceptos básicos que usaremos en nuestras futuras publicaciones para hablar de la oxigenación oceánica en el pasado. Los científicos usan equipos especializados para medir el OD en el océano. @pages-ipo.bsky.social

New study: More oxygen in the oxygen-minimum zone associated with weaker Atlantic overturning circulation - now in Nature Communications. @marumunibremen.bsky.social @kielunimarine.bsky.social @sofigerina.bsky.social #ClimateChange #AMOC #OceanScience #Foraminifera #PaleoData

In this paper, we present new global calibrations for the I/Ca proxy for ocean oxygenation, with the first Pacific transect. By comparing data from planktonic foram species that live at different water depths, we gain a better understanding of the proxy and its relationship to O2 #paleoceanography

Hi 🤓🌊🌍ocean oxygen community. 💡📑Abstract submission is now open for the American Geoscience Meeting - AGU @agu.org. We want to invite you to join our PO2 session about past, present and future deoxygenation. In the following QR you will find information about our session and travel funding options.

Hola otra vez !!!🤓🌊🌎 (pero en Español)💡 Hoy vamos a hablar de foramíniferos con la ayuda de SciCoForams una iniciativa de comunicación científica de @sofigerina.bsky.social Los foraminíferos o abreviado “forams” 🐚son organismos unicelulares que habitan los océanos desde hace 541 millones de años.

Hi again!🤓🌊🌎 Today, we want to talk to you about foraminifera with the help of SciCoForams an independent #scicomm initiative by Sofía Barragán-Montilla @sofigerina. Foraminifera, or “Forams”🐚 for short, are single-celled organisms that have lived in the ocean for over 541 million years.

Less ocean O₂ overall, with strong regional shifts—incl. hypoxia in the Mediterranean due to monsoon-driven stratification. Read here: cp.copernicus.org/articles/21/... @good-ocean-oxy.bsky.social @pastoxygen.bsky.social @katrinmeissner.bsky.social @oceano2.bsky.social
