I learned about a brilliant project yesterday to support British Sign Language (BSL) users, creating new signs for scientific terms in chemistry, oceanography, data science & more.
And they're fabulously descriptive. Do have a look and share!

πŸ™€Invasive species cause such diverse ecological impacts that we needed to broaden the lens used to classify their effects. Very happy with the collaborative and progressive nature of this work, integrating previous efforts and helping fill key gaps after years of worldwide effort!

Lots of challenges and excitement since deciding to move back to Ireland and establish Atomic Ecology but getting to pass through Dublin on a sunny spring morning is definitely good for the soul

Online Courses | Atomic Ecology Online training in the application of stable isotopes to ecological and environmental research

If stable isotopes are part of your research, they should be one of your strengths β€” not something you β€œsort of” understand.

That’s why I built this course.

skin values didn't change. A comparison of both tissues can help to estimate time since death and skin data provides a decomposition resistant signature of diet or location!

Online Courses | Atomic Ecology Online training in the application of stable isotopes to ecological and environmental research

Most isotope users were never formally trained in isotope ecology.

They learned just enough to get by.

That gap shows up later β€” usually during interpretation.

That’s exactly what my course is designed to fix.

Nitrate | Atomic Ecology Isotopic approaches to nitrate measurements and management

Europe has a nitrate problem - essential to our agriculture but harmful to freshwater and coastal habitats, nitrate pollution has become fact of life. Isotopes have a huge, but largely untapped, potential to identify point sources of nitrate and also estimate where that nitrate originated.
