08-18 May 2020. A massive red-tide in our region prompted our lab to conduct rapid-response field work, applying for and gaining permissions to conduct limited field equipment swaps during these severely restricted covid19 times. We practiced careful social distancing and sanitizing measures throughout. We were able to swap our biosensor moorings, download the data, and re-deploy to capture the start and end of the red-tide and the response within Los Peñasquitos Lagoon. In addition to the striking bioluminescence, the bloom brought with it widespread hypoxia and fish and invertebrate kills. Greg Boyd was irreplaceable during this work, he single-handedly (due to covid restrictions) performed the bulk of the actual recoveries and deployments!
