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 2) to yield grain size and mineralogical data. The dataset, CRKR2013-2014_SEDIMENT_Mineralogy.zip contains a spreadsheet with mineralogical data for each sample. The dataset, CRKR2013-2014_SEDIMENT_GrainSize.zip contains a spreadsheet with grain size data for each sample. 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. Supplemental_Information: Sediment analyses, except for mineralogy, were performed at the Eckerd College Sedimentology Laboratory by Christopher S. Moore under the guidance of Eckerd College professor Dr. Gregg Brooks (see Poppe et al., Gibbs 1974, Folk 1965, Milliman 1974, and Dean 1974 listed in Cross Reference section). Mineralogical analyses, including photomicrographs, were performed under the direction of Dr. William Benzel at the USGS Central Minerals and Environmental Resources Science Center, located in Denver, Colorado. The data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2013-097.

Wet samples were dehydrated to remove water and salts within 6 hours of collection by rinsing with 95% denatured alcohol, allowing samples to settle, decanting the alcohol, and repeating this process two additional times. Samples were then allowed to air dry prior to analysis for grain size and mineral composition.

Each day's settling tube operations were compared to known laboratory standards at the Eckerd College sedimentary lab. Calcium carbonate content was determined by the acid leaching method (Milliman, 1974). Total organic matter (TOM) was measured by loss on ignition (LOI) at 550 degrees Celsius for > 2.5 hours (Dean, 1974).
