Today’s a special day. it’s World Science Day for Peace and Development! 🌍✨It’s all about boosting public awareness, sharing knowledge, and teaming up across borders. Because when nations unite through science, we get closer to figuring out how to live in a peaceful, sustainable world, together! 🔬🤝💚

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

📑🔬¿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.

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.

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

📝Ocean Dissolved Oxygen?🌊🤓 Do you know what it is❓ We are gonna talk about some general concepts we will use in future posts to talk about past ocean oxygenation. Scientists use special equipment to measure DO in modern oceans. @pages-ipo.bsky.social

It is measured in μmol/kg (micromoles/ kilogram): the concentration of oxygen molecules (O2) in a kilogram of water. Solubility plays an important role in the amount of dissolved oxygen in ocean waters. It increases when ocean waters are colder, with lower pressure and low salinity.
