Grossman Lisa Marrack 2019 data release DOI: 10.5066/F7154FJQ Pacific Coastal and Marine Science Center, Santa Cruz, CA U.S. Geological Survey https://doi.org/10.5066/F7154FJQ Conductivity-Temperature-Depth (CTD) profile data were collected along transects across study areas of west and east Hawaii Island between 2010 and 2014. Measurements were made over a range of tide and weather conditions and help characterize the spatial extent and variability in estuarine conditions across the reef when grouped by 1 to 2-hour survey period or by season. Sites of cold and warm groundwater discharge along east Hawaii were characterized for comparison. Spatial measurements of water temperature and salinity from a range of depths and distances from shore were collected to characterize the temporal and spatial variability in water temperatures that influence coral reef habitats, coral health and the vulnerability of coral to bleaching. These data also establish important baseline information with which to track and identify changes owing to climate and land use change, including changes in runoff of terrestrial water and contaminants that can affect the quality of habitat for corals, fish and other wildlife of concern. Along the arid west coast of Hawaii Island terrestrial inputs of water occur primarily in the form of groundwater and this study focused on examining the extent that groundwater inputs to the coast influences coral reef water temperatures, coral health, and potential cold water refugia where corals may find resilience in light of observed increases in global coral bleaching associated with rising sea surface temperatures.

No formal attribute accuracy tests were conducted. No formal logical accuracy tests were conducted. Data are complete as presented. Users are advised to read the rest of the metadata record carefully for additional details. Stated horizontal accuracy of the Sontek CastAway GPS is +/- 10 m. Stated vertical accuracy of the Sontek CastAway is+/- 0.01 m. Water temperature, specific conductance, salinity, and density were measured through the water column on transects along and across shore with a Sontek CastAway Conductivity-Temperature-Depth (CTD) sensor. Latitude and longitude for each measurement were collected with the internal GPS of the sensor. 2016 Edited metadata to add keywords section with USGS persistent identifier as theme keyword.
