|Hardbottom||This category commonly harbors varieties of octocorals, sponges, algae, the fleshy colonial zoanthid Palythoa caribaeorum, the fire corals Millepora alcicornis and M. complanata, other encrusting reef-associated organisms, coral skeletons, rubble and sands, and a few isolated live, stony, head-coral species.|
|Rubble||This category consisted primarily of clearly identifiable A. cervicornis sticks intermixed with carbonate fragments of other shapes and sizes of indeterminate origins.|
|Sand||This category did not differentiate between coarse- and fine-grained size fractions, although clarity of the ATRIS imagery would have allowed for such distinction.|
|Seagrass||This category included the most prevalent type of seagrass-the turtle grass Thalassia testudinum-occasionally mixed with the manatee grass Syringodium filiforme.|

Acknowledgment of the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected. Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. Users should be aware that comparisons with other datasets for the same area from other periods may be inaccurate because of inconsistencies resulting from changes in photointerpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such.
Images were collected to support the Reefscape Geologic-framework task of the USGS Coral Reef Ecosystem Studies project (https://coastal.er.usgs.gov/crest/). Benthic composition, topographic relief, areal extent, and temporal stability are critical factors that contribute to the value of a given marine habitat. To provide context for the data collected in the other tasks, the focus of this task was to characterize physical aspects of the project study sites, including habitat classification, sediment distribution, and vertical temperature profiles. The images used to help create the habitat map were acquired during USGS field activity number 2014-313-FA, additional survey and data details are available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-313-FA.
Are there legal restrictions on access or use of the data?
