Isotopes, fish, footy and more isotopes.... Prof at University of New Brunswick

Environmental science 63%
Geography 17%

Very cool work Eric! Not sure if it has been done before but combining with isotopes to assess seasonal shifts in productivity associated with DNA abundance could be neat.... I have some (as yet unpublished) SIA data from eastern Canada showing similar patterns in streams there...

Is your New Years resolution to learn more about sharks? (Just kidding, I assume that's everyone's New Years resolution!)

Good news! We are offering my online take-at-your-own-pace "Biology and Ecology of Sharks and Their Relatives" course again, starting in February!

📢 Upcoming Webinar: Atomic Ecology Meets Dr Sora Kim!

Later this week, I’ll be launching the first in a new series of webinars titled 'Atomic Ecology Meets'. These are designed to sit somewhere between a podcast and a seminar, providing a small (but powerful) dose of high quality science along
🎤 NoWPaS 2026 Keynotes are out!
Four speakers • Three countries • Cutting-edge salmonid research
Physiology, isotopes, genetics & migration 🌊🐟

Happy New Year from Atomic Ecology 🌱

This year I’ll be sharing more about how stable isotopes help answer practical questions in food systems, fisheries, and environmental management — not just theory, but tools you can use.

Looking forward to the conversations ahead.

Multiple mega-farms in the Lough catchment + sewage outlets + septic tanks. That's a whole lot of poo, containing a whole lot of nitrates + phosphates with the potential to end up in the Lough, feeding algae. You can explore on our Watershed Pollution Map:

Always a please to enjoy the winter sun in Salford. Thanks for a great visit!
Delighted that one of my Antarctic winter photos has won the 2025 Royal Society Photography Competition, Earth Science & Climatology category.

Captured during polar-night surveys of ocean conditions near Antarctic Peninsula glaciers.

This was a LOT of work — filming, writing, editing, R coding… and a slightly unhealthy amount of coffee. Very pleased with the outcome though, time well spent!

Over the last 15–20 years I’ve helped hundreds of researchers, students, labs, and agencies. The same questions kept coming up. The same mistakes. The same “aha!” moments.

So I built the courses I wished I had when starting out.

Why create two full stable isotope courses?

Because more and more people rely on isotopes — but very few get proper training in how to design studies, interpret data, or use tools like simmr or MixSIAR with confidence.
