Data were collected in the Auau Channel, Main Hawaiian Islands, to support benthic habitat mapping efforts during the HURL Ship R/V Ka'imikai-o-Kanaloa cruise in April 2009. These data provide optical observations that will be used to provide information on the location and distribution of mesophotic coral ecosystem communities between approximately 40 and 150 m depths. Refer to supplemental information for description of instrument and survey.

Topography of the channel consists of solution basins and rims (ridges), sediment plains and reef pinnacles on the channel floor, which were subaerially exposed during late Quaternary lowstands of sea level. Holocene reef growth occurs as a thin veneer on topographic highs in the Channel. The Channel reaches depths of 140 m, however, the majority of the seafloor is between 55 m and 100 m deep. The Auau Channel has been documented to include abundant coral reefs at these depths, which along with algae and other organsims found there, collectively form mesophotic coral ecosystems. Optical validation data were collected using HURL's RCV-150 remotely operated vehicle (ROV), deployed during nighttime hours usually between 1900 and 2300 (Hawaii time). Equipment description: The RCV-150 system consists of a remotely operated vehicle with a color analog video camera, two parallel lasers for scale, and six 250 W lamps. This was deployed from the HURL ship, R/V Ka'imikai-o-Kanaloa. A heavy cage was deployed off the ship's J-frame to whic the ROV was tethered, using a dedicated winch. The ROV operators maintain the ROV, or at least the glow from its lights, within sight of a downward-looking video camera on the cage. This keeps the horizontal distance between the ROV and the cage within 15 m for most deployments. Lighting mounted on the base of the cage provided additional illumination to the ROV.

There are two primary sources of this error. The ship's positioning is based on non-differential GPS positioning, which has an accuracy of under 5 meters. The second and and larger source of error is the uncertainty associated with the ROV's position relative to the ship's antenna. This includes the offset of the cage from which the ROV is deployed, relative to the ship's antenna (approximately 10 m) and the distance the ROV may be from the cage (usually < 15 m). Complete Unspecified Following the cruise, the navigation file providing the position of the ship during the tow was entered into an Excel spreadsheet and formatted and then imported into ArcGIS v 9.3. These coordinates provided the ship's position approximately every second. Points were extracted to provide positions for points at 30-seconds intervals. These positions are used as the best indication of the position of the ROV during the tow, bearing in mind the limitations of the horizontal positional accuracy described above. Spreadsheets containing location and time data were then used to classify benthic habitat for each tow using the Pacific Coral Reef Ecosystem Benthic Habitat Mapping classification scheme. Five points were classified at 30 second intervals and codes were inputted into the spreadsheet. The spreadsheet was saved as dbase file, imported into ArcGIS v9.3, and saved as a shapefile. Percent cover of scleractinian coral was displayed in Optical Validation maps with classifications of other types of living cover and substrates contained within the attribute table of the shapefile. 2010-05-29T00:00:00 otherRestrictions Metadata Access Constraints: None otherRestrictions Metadata Use Constraints: None annually This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
