Dataset: Coral photransect and settlement tile images from St. John, USVI 1987-2019

The data present the original images recorded as photoquadrats from the reefs of St. John from 1987 - present. Image up until (and including) 2000 were recorded on color film and were digitized; all other images were collected digitally with resolutions that changed with upgraded camera technology. All images are provided as jpegs, which most end users will find useful to support new analyses. More recent images are also available as RAW files (Nikon format) that can be used for more manipulations of quality. Detailed field methodology is described in the papers published from this site, for example: Edmunds PJ (2013) Marine Ecology Progress Series 489: 107-123, Edmunds PJ and Smith TB (2022) Marine Biology 169: 60, Edmunds PJ (2019) Ecology e02587

Problems/issues: Some irregular number of quadrats were samples at some sites in some years.
