Abstract:
Understanding the processes that govern whether a coral reef is accreting (growing) or dissolving are fundamental to questions of reef health and resiliency. A total of 52 surficial sediment samples were collected within a 1-km x 1-km area around Crocker Reef in the Florida Keys, USA, between 2013 and 2014. Samples 1-35 were collected in July 2013 and samples 36-52 were collected in July 2014. The samples were processed using conventional, published techniques (see process step section) to yield grain size and mineralogical data. The dataset, CRKR2013-2014_SEDIMENT_Images.zip contains photomicrograph images that correspond to each sediment sample. These images also include additional, survey-specific EXchangable Image File format (EXIF) header information.
Purpose:
Sediment data were collected to support the Reefscape Characterization task of the USGS Coral Reef Ecosystem Studies project (
http://coastal.er.usgs.gov/crest/), which is focused on geochemical, geologic, and metabolic processes that affect carbonate precipitation and dissolution of coral reefs. 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 is to characterize physical aspects of the project study sites. Characterizations of the Crocker Reef study area include a habitat classification map, sediment distribution, and vertical temperature profiles. Sediment samples were acquired during USGS field activity number 13CRE02 in 2013 and 2014-315-FA in 2014.
Sediment analyses, except for mineralogy, were performed at the Eckerd College Sedimentology Laboratory by Christopher S. Moore under the guidance of Dr. Gregg Brooks (see Poppe et al., Gibbs 1974, Folk 1965, Milliman 1974, and Dean 1974 listed in Cross Reference section). Mineralogical analyses were performed under the direction of Dr. William Benzel at the USGS Central Mineral and Environmental Resources Science Center, located in Denver, Colorado. The data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2013-097.

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.
