As part of a new NSF-funded project, I am collaborating with coPIs Geno Pawlak (UCSD), Kristen Davis (UCI) and Rachel Collin (Smithsonian Tropical Research Institute) to examine the physical processes impacting the formation and breakdown of hypoxia in a tropical estuary. Our field site is Bocas del Toro, Panama, an enclosed tropical bay that experiences seasonal and intermittent hypoxia. During January 2020 several of us went to help graduate student Annie Adelson recover, download, reprogram, and redeploy a large mooring array in the bay. Annie spent five months during 2019-2020 living as a Smithsonian Institution Fellow at the STRI Bocas del Toro Research station. It was an intense but successful field campaign!
