Miller Lite is a bad beer but an incredible beverage, Tyler Austin Harper argues: “It is neither complicated nor offensive, and it derives its magic from this bland alchemy, this delicate equipoise of fizzy nothingness.”

The aim of this home made, low cost, system Ed is working on is to measure fluxes of carbon dioxide and methane (diffusion and bubbles) 6 times a day, 7 days a week, hopefully 365 days the year on all 24 mesocosms. That will 52 560 flux estimates, though we might miss a couple over the year!

Great paper that highlights the performance of four lake models (bulk, energy balance, and 2x k-Epsilon models) on lakes, globally! There’s no clear winner. Some perform well there, some better there. So, using ensemble modeling is the path forward to improve projections and state uncertainty 🌊🌡️💧

We’re actively collaborating with colleagues from UW-Madison, Virginia Tech and Pittsburgh Uni on innovative models for Ecological Knowledge-Guided Machine Learning! So far, integrating a deep learning model directly into a process-based model seems very promising for non-linear ecological dynamics.
