Conductivity-Temperature-Depth (CTD) profile data were collected along transects and across study areas of west 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.

Spatial measurements of water temperature, specific conductance, salinity, pH, and dissolved oxygen 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 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.

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.

Stable isotope data of fauna, particulate organic matter, and rocks collected during the 2018 research cruise aboard the NOAA Ship Bell M. Shimada that examined benthic communities off the western U.S. coast.

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.

This dataset consists of raster geotiff outputs of relative environmental favorability for coral growth and survival in the United States territories of Guam and American Samoa across 3 climate scenarios: Present, Intermediate Emissions (Representative Concentration Pathway 4.5), and Worst Case Emissions (Representative Concentration Pathway 4.5). These datasets were generated from a synthesis of spatial variability in many environmental conditions, including thermal stress, wave power, irradiance, chlorophyll concentrations, macroalgal cover, calcite concentrations, turbidity, and erosion. Input conditions were classified as “Managed” or “Non-managed” based on whether the condition could be managed at the island...

Data to support the site characterization of locations sampled along the continental shelf and slope of the western U.S. coast off Washington, Oregon and California during the EXPRESS RL1905 expedition in 2019. Data consisted of tissue samples from fauna, sediments and particulate organic matter. These samples were analyzed for stable carbon and nitrogen isotopes to examine food web ecology. Additional observational data were collected through video analyses with efforts focused on documenting counts of fauna other than corals, sponges and fishes, as well as general habitat characteristics.

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.

This part of the release provides an updated georeferenced catalog of limestone boulders and cobbles pertaining to extreme waves on Anegada, a low Caribbean island perched south of the Puerto Rico Trench. Tabulated are 660 limestone clasts, along with clast dimensions and long-axis trend in many instances. Fewer than one-fifth of the clasts were reported previously in https://doi.org/10.1007/s11069-011-9725-8 and https://doi.org/10.1130/GES01356.1. Most were surveyed in 2017.

This release provides inventories of georeferenced evidence pertaining to extreme waves on Anegada, a low Caribbean island perched south of the Puerto Rico Trench: CORAL BOULDERS AND COBBLES -- Derived offshore, found inland. Boulder star coral Orbicella franksii (37 localities), brain coral Pseudodiploria strigosa (171), elkhorn coral Acropora palmata (36), mustard hill coral Porites astreoides (29). LIMESTONE BOULDERS AND COBBLES -- Derived and found onshore (633). MOLLUSCAN SHELLS -- Queen conch Aliger gigas, discarded by precolonial fishers (12 onshore heaps) and by modern fishers (40 offshore heaps); individual conch shells deposited inland by precolonial sea flood (59); tiger lucine Codakia orbicularis, also...

This part of the data release provides an updated georeferenced list of radiocarbon ages pertaining to evidence for a catastrophic precolonial sea flood on Anegada, a low Caribbean island perched south of the Puerto Rico Trench. The list contains 64 ages measured on carbonate materials and 3 ages measured on plant fragments. Among the total of 67 ages, 43 are among the 47 ages previously tabulated on page 318 of https://doi.org/10.1130/GES01356.l. The 67 ages exclude those from previous work on deposits attributable to the 1755 Lisbon tsunami (https://doi.org/10.1007/s11069-010-9622-6). Among the 67 ages listed, the 24 ages previously unreported were measured mainly on samples collected in 2017. The main material...

Observations of coral disease and health indicators 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, types and number of indicators observed, and a size range of indicators observed.

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,...

This data set includes still images and videos from three bays within Hurricane Hole, Virgin Islands Coral Reef National Monument, documenting the remarkable biodiversity of the coral/mangrove ecosystem within these bays, and the effects of the 2017 Hurricanes Irma and Maria on this unique ecosystem. Near shore marine communities and fringing red mangroves were severely damaged.

This part of the data release provides an updated georeferenced guide to the main unit of Holocene sand ascribed to a sea flood on Anegada. Much of the data was previously summarized in Figure A4 of https://doi.org/10.1130/GES01356.1 . Plotted here, on the accompanying map, are all 573 localities in the updated compilation —nearly half of which do not provide much if any evidence for marine inundation. The main attribute of each locality is one of four summary categories: Pervasive—Sand covers more than 3/4 of area and typically thicker than 5 cm (132 localities). Patchy—Sand covers less than 3/4 of area and typically thinner than 5 cm (185 localities). Scant—Called “Sand scarce or absent” in https://doi.org/10.1130/GES01356.1...

This part of the release provides an updated list of places on Anegada, none of them more than 0.5 m above sea level, where observed sandy deposits may represent the Lisbon tsunami of 1755 C.E. These places were previously plotted in Figure A3 of https://doi.org/10.1130/GES01356.1, a paper in which the Lisbon tsunami is inferred to have had minor effects on Anegada compared with a sea flood a few centuries earlier. Details about the low, probable Lisbon deposits were previously reported in https://doi.org/10.1007/s11069-010-9622-6 (stratigraphy), https://doi.org/10.1007/s11069-011-9730-y (molluscan paleontology), and https://doi.org/10.1007/s11069-010-9706-3 (foraminifera).
