| Purpose | Quantify nearshore water quality conditions and the extent and volume of submarine groundwater discharge (SGD) plumes across west Hawaii coral reefs. Test whether coral bleaching and disease are linked to exposure to SGD or lack thereof. Quantify coral cover and community composition and changes through time at select monitoring sites. Determine the fate of SGD within coral reef settings. | ||||||||

| Coral bleaching data by site, West Hawaii, 2010-2011 | scuba | Observations of bleached coral were documented by scuba divers along pre-determined transects and are presented here in comma-separated format. Included in the table are coral species observed, colony size, size of bleached area on colony, and seawater temperature. | Eric Grossman |
| Coral Point Count (CPCe) summary data by transect, West Hawaii, 2010-2011 | camera | Coral Point Count with Excel extensions (CPCe, Kohler and Gill, 2006) was used to help calculate percent of coral cover or other benthic substrates from a randomly selected subset of seafloor photographs collected on the west Hawaii Island coast. | Eric Grossman |
| Seafloor photographs and location data, West Hawaii, 2010-2011 | camera | Seafloor photographs were collected by SCUBA divers along pre-determined transects using an underwater digital camera following benthic survey protocols developed by the National Park Service (NPS) at Kaloko-Honokohau National Historical Park (Marrack and others, 2014, Weijerman and others, 2014) and modeled after the U.S. Geological Survey (USGS) and NPS coral reef survey protocols (Rogers and others, 2001, Brown and others, 2011). This dataset includes seafloor photographs in jpg format, the locations of which are described in the accompanying comma-separated files. | Eric Grossman |
| Water level, temperature, and salinity time-series data from nearshore coral reef locations along the west coast of Hawaii Island (2010-2011) | CTD | Time-series data of water level, water temperature, and salinity were collected at 10 locations along west Hawaii Island between 2010 and 2011 in nearshore coral reef settings. Conductivity-temperature-depth sensors were attached to fossil limestone, rock, or dead coral within otherwise healthy coral reef settings spanning water depths of 8 to 23 ft. Continuous measurements were made every 10 or 20 minutes. | Eric Grossman |
| Conductivity, temperature, and depth (CTD) data from nearshore coral reef locations along the west coast of Hawaii Island (2010-2014) | CTD | 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. | Eric Grossman |
| Water temperature time-series data from nearshore coral reef and anchialine pool locations along the west coast of Hawaii Island (2010-2013) | samples | Time-series data of water temperature were collected at 33 locations along the west coast of the Island of Hawaii, including within Kaloko-Honokohau National Historical Park (KAHO), and Puu o Honaunau National Historical Park (PUHO) between 2010 and 2013 in nearshore coral reef and anchialine pool settings. Temperature sensors were attached to fossil limestone, rock or dead coral within otherwise healthy coral reef settings spanning water depths of 0.1 to 8.84 m (0.3 to 29.0 ft). Continuous measurements were made every 10 or 20 minutes. Due to the large amount of data, the dataset has been split into three files. WaterTempTimeSeries_KAHO-KC.csv includes data from nearshore coral reef locations within Kaloko Bay, which lies within the KAHO boundaries, WaterTempTimeSeries_KAHO.csv includes data from nearshore reef locations and two anchialine pools within the remainder of KAHO, WaterTempTimeSeries_westHawaii.csv includes data from nearshore coral reef locations along west Hawaii coastline, outside of the KAHO boundaries. | Eric Grossman |
| Surface-water temperature, salinity, pH, dissolved oxygen, and turbidity data from nearshore coral reef locations along the west coast of Hawaii Island (2010-2013) | samples | Spatial measurements of water temperature, specific conductance, salinity, pH, dissolved oxygen, and turbidity between 0.25 and 0.50 m water depth were collected every 10-seconds along and across shore at 12 principal study areas along west and east Hawaii Island. Measurements were made between 2010 and 2013 during different seasons and tide states over the course of 1.0 to 2.5 hours to evaluate the spatial and temporal extent of water properties that influence coral reef health and coral reef habitat availability. | Eric Grossman |
