Data provided in this dataset are benthic habitat imagery that result from benthic photo-quadrat surveys conducted along transects at stratified random sites surveyed across the Main Hawaiian Islands during the 2019 bleaching event. The data were collected by the NOAA Ecosystem Sciences Division (ESD) during a multi-institutional effort by the Hawaii Coral Bleaching Collaborative (HCBC) to build a comprehensive dataset of the spatial extent and severity of bleaching in the Hawaiian Archipelago during the peak of the forecasted 2019 coral bleaching event. These photo-quadrat surveys were conducted during shore-based missions and were analyzed for benthic cover for which data is described at: "https://www.fisheries.noaa.gov/inport/item/59195".

A stratified random sampling (StRS) design was employed to select random sites. The survey domain encompassed the majority of the mapped area of reef and hard bottom habitats in the 0-30 m depth range. The stratification scheme included island, reef zone, and depth in all regions, as well as habitat structure type in the Main Hawaiian Islands. Sampling effort was allocated based on strata area and sites were randomly located within strata. Sites were surveyed using photo-quadrats along transects to collect benthic imagery to ultimately produce estimates of relative abundance (percent cover), frequency of occurrence, benthic community taxonomic composition and relative generic richness.

The StRS design effectively reduces estimate variance through stratification using environmental covariates and by sampling more sites rather than sampling more transects at a site. Therefore, site-level estimates and site to site comparisons should be used with caution.

Purpose Working with the Hawaii Coral Bleaching Collaborative (HCBC), NOAA ESD planned and executed a field survey response in 2019 that applied a structured, hypothesis-driven approach to document the extent of coral bleaching in the Hawaiian Archipelago, and laid the groundwork for tracking coral response and recovery through time.

Processing Steps
  • Parameter or Variable: PHOTOQUADRAT IMAGES (Measured) (measured); Units: unitless; Observation Category: in situ; Sampling Instrument: camera; Sampling and Analyzing Method: Photoquadrat surveys were conducted by both the fish and benthic teams. Still photographs were collected to record the benthic community composition at predetermined points along the transect line with a high-resolution digital camera mounted on a pole. Overall, 30 photoquadrat images are collected at each site. The fish team conducts these surveys along one 30-m transect that spans the length of two stationary point count (SPC) cylinders used to assess fish abundance (30 images total).The benthic team conducts the photoquadrat surveys along one 30-m transect, where one photo is taken every meter for a total of 30 photographs.; Data Quality Method: The photos are reviewed by the diver for accuracy and usability. To ensure consistency, images were color corrected using Adobe Lightroom if it appeared that the camera they were taken from was not properly white balanced in the field. Typically, 30 photographs are collected per site; however, there may be instances in which camera issues, survey conditions, or image quality results in fewer than the standard 30 photos per site..
