Watch Stephanie Tsui (Ph.D. candidate in the Bowen Lab @bowenlab.bsky.social ) and me carefully remove the sediment from the surface down to 30 cm from a marsh organ pipe in South Carolina. The different pipe elevations represent different marsh elevation/sea-level rise scenarios. It's muddy work!

Check out the incredible density of fiddler crabs in the #saltmarsh at North Inlet-Winyah Bay National Estuarine Reserve, where colleagues and I were measuring nitrogen cycling in June 2024.

and the water and added nitrate is mixed using this fun magnet trick, all without mixing the porewater with the atmosphere, which would affect its dissolved gas content. Then that mixture is then pumped ("pushed") back underground to incubate over the course of high tide.
