|---|---|---|---|
| Structure from Motion - UAS | --- | Photo | 3D bathymetric surfaces of low- and high-relief sites (3D bathymetric surfaces of low- and high-relief sites from the coral reef flat off Waiakane, Molokai, were created using structure-from-motion (SfM) techniques.) Ground control point locations for the UAS survey (This portion of the data release presents the locations of the temporary ground control points (GCPs) used for the structure-from-motion (SfM) processing of the imagery collected during an unoccupied aerial system (UAS) survey of the coral reef off Waiakane, Molokai, Hawaii, on 24 June 2018. The GCP positions are presented in a comma-delimited text file.) Orthomosaic imagery from the UAS survey (This portion of the data release presents a high-resolution orthomosaic image of the coral reef off Waiakane, Molokai, Hawaii. The orthomosaic has a resolution of 2.5 centimeters (cm) per pixel and was derived from structure-from-motion (SfM) processing of aerial imagery collected with an unoccupied aerial system (UAS) on 24 June 2018. ) Refraction-corrected bathymetric point cloud from the UAS survey (This portion of the data release presents a bathymetric point cloud from an unoccupied aerial system (UAS) survey of the coral reef off Waiakane, Molokai, Hawaii, on 24 June 2018.) Refraction-corrected bathymetric digital surface model (DSM) from the UAS survey (This portion of the data release presents a bathymetric digital surface model (DSM) from an unoccupied aerial system (UAS) survey of the coral reef off Waiakane, Molokai, Hawaii, on 24 June 2018.)

| instrumentmooring | --- | Mooring (physical oceanography) | West Maui, Hawaiian Islands, wave and water level data, 2017 (Time series data of wave height and water surface elevation were acquired at ten locations for 75 days south of Lahaina, off of the west coast of the island of Maui, Hawaii, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs.) Waiakane, Molokai, Hawaiian Islands, wave and water level data, 2018 (Time series data of water surface elevation, wave height, and water column currents and temperature were acquired at seven locations for 86 days off of Waiakane on the south coast of the island of Molokai, Hawaii, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs. ) |
