Location
Middle and Lower Florida Keys, United States, Atlantic Ocean
Summary
Collected in situ measurements of reef elevation and associated photos.
Info derived
In situ measures of reef elevation and associated underwater photographs at various established monitoring sites.
A Canon Powershot S120 was used in conjunction with the associated Ikelite underwater housing to capture still images. Camera settings varied depending on underwater conditions but were manually adjusted. Shutterspeed was set to a fast setting (minimum of 1/250) to account for moving objects. ISO was adjusted based on light availability on each dive. Aperture was set to a low setting and usually not adjusted. All images were shot in RAW to allow for ease of post-processing. Manual focus was used.
