New technological approaches in marine ecology, such as (1) passive acoustics to characterize underwater soundscapes, and (2) habitat photogrammetry, which provides high-res, 3D images of habitats, can facilitate efficient and accurate assessments of coral reefs. In collaboration with the Florida Fish & Wildlife Conservation Commission (FWCC) and NOAA’s National Marine Sanctuary Program (NMSP), multidisciplinary, non-invasive research approaches provide transformative ways to characterize reef fish biodiversity as well as the ecological function of essential, hard-bottom habitats. The Florida Keys National Marine Sanctuary (FKNMS) is an ideal study system due to several replicate marine reserve types in addition to existing historical data on reef fish and benthic communities. Underwater soundscape results show significantly different spectral patterns for each site, such that protected sites displayed higher average spectra in low frequencies than fished sites. Additionally, species and family-specific fish chorusing was identified during crepuscular hours at several protected sites. Photogrammetry surveys produced a 3D elevation model used to characterize differences in coral composition contributing to vertical relief. Initial results suggest biodiversity and other ecosystem metrics generally increase with level of protection. These data provide critical baseline evaluations for Post- Hurricane Irma impacts and may assist in monitoring the recovery of coral reefs.
