In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Distribution of Sediments at Crocker Reef, Florida, 2013-2014

Summary
Understanding the processes that govern whether a coral reef is accreting (growing) or dissolving are fundamental to questions of reef health and resiliency. The Reefscape Characterization task of the Coral Reef Ecosystem Studies (CREST) project is focused on geochemical, geologic, and metabolic processes that affect carbonate precipitation and dissolution on coral reefs. For the 1-kilometer (km) x 1-km study site around Crocker Reef in the Florida Keys, 52 surficial sediment samples were collected and processed to yield grain size and mineralogical data. Samples 1–35 were collected in July 2013 and samples 36–52 were collected in July 2014. Grain size data are reported on a percent-weight basis for phi (Φ) sizes ranging from -2 to 12. The data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2013-097.
