Program Info

MarineGEO ( is a global program. MarineGEO - Indian River Lagoon focuses on both monitoring and experimental work in the Indian River Lagoon, including: annual monitoring of local seagrasses, oyster reefs, soft-sediment (infauna), artificial structures, and mangroves. The MarineGEO program is strongly focused on change of biodiversity over time with manipulative experiments on the causes and consequences.
reef area (m^2), reef height (cm), oyster percent cover (point-intercept), oyster size frequency distributions (mm), counts of oysters and associated organisms; water temperature (deg. C), salinity, dissolved oxygen (mg/l), CDOM (QSDE), chlorophyl a (ug/l)
MarineGEO needs to be notified and authored on any technical reports or other written products that use their data: Dean S Janiak, Biologist – MarineGEO, Smithsonian Marine Station, 701 Seaway Drive, Ft Pierce, Florida 34949, 772.462.0991
Quadrats placed randomly along transects; 1m x 1m quadrats with 100-point grids used for percent cover (point-intercept method); 25cm x 25cm quadrats used for oyster and associated organisms size measurements and counts (sizes measured in mm, up to 50 randomly selected oyster specimens including both live and dead articulated oysters - live versus dead measurements are denoted in the data set); bio-boxes used to census reef-associated fauna >500um. Reef area was initially assessed by GPS and drone photography, but the spreadsheet indicates these measurements are being redone in consultation with the Florida Fish and Wildlife Conservation Commission.
Not sampled in 2020 due to COVID-19.
