Excited to see our piece advocating for embracing (or at least acknowledging) artificial aquatic ecosystems published! Indefatigable leadership from @jackiewebb.bsky.social to transform our casual conference chats to this powerful (imho) piece. onlinelibrary.wiley.com/doi/10.1002/...

Sampling frequency matters! Our new study utilizes a low-cost, high-freq system to track GHG fluxes over 7 months. If we don't measure often, fluxes can get heavily skewed. That's why affordable, high-freq systems are a game-changer for tracking freshwater GHG fluxes. doi.org/10.1002/lom3...

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!
