Hawaii Coral Bleaching Collaborative 2019 Surveys: Observation Entities

Descriptive name for DATASET_ID.

Unique ID for a given dataset (13 total for 2019). Format = agency abbreviation and dataset number (e.g., DAR_01, ESD_02).

Name of organization / office / project that owns and manages a given dataset. A dataset can be owned/managed by +1 organizations (e.g., DAR_Kona, DAR_Kauai, DAR_Maui).

Initials of person who made this particular observation.

Name of Hawaiian island/atoll.

Name of island group (i.e. NWHI vs. MHI). MHI = main Hawaiian Islands; NWHI = Northwestern Hawaiian Islands

Name of sub-island zone (e.g., North Hilo, South Kohala). Applicable only to islands in the MHI (not required).

Unique name for survey conducted (unique for each record in the observations data).

Alternate survey identification internal to organization (optional). Applies to observations in the MHI only.

Average depth in feet for the observation or survey site. Depth ranges from 2-98 ft. If null, refer to DEPTH_BIN. For HIMB surveys, the exact depth for each survey was not recorded and instead was estimated at 6.5 feet.

Depth bin was retroactively determined if the observer did not record DEPTH_FT during a survey (e.g., DAR Maui surveys). Shallow: 0–6 meters; Mid: >6–18 meters; Deep: >18 meters

Latitude of observation in decimal degrees (19-28.5 degrees). Assume centroid of observation area unless stated otherwise in COMMENTS_OBSERVATION (e.g., transect start, transect stop, approximated from google maps, etc.). WGS84 datum assumed unless stated otherwise.

Longitude of observation in decimal degrees (-178.4 to -155 degrees). Assume centroid of observation area unless stated otherwise in COMMENTS_OBSERVATION (e.g., transect start, transect stop, approximated from google maps, etc.). WGS84 datum assumed unless stated otherwise.

Local date observation was made (m/d/yyyy; 8/27/2019 to 11/5/2019).

Area in square meters surveyed for the observation; not the total area for the complete survey or dataset (78.5 - 393 m^2).

Percent of living coral cover within the area of this observation (0-100%). If NULL, see LiveCoralCover_Bin.

Percent living coral cover within the area of this observation to the nearest bin (Bin 0 = 0%, 1= 1-10%, 2 = 11-30%, 3 = 31-50%, 4 = 51-75%, 5= 76-100%). If NULL, see LiveCoralCover.

Percent of living coral cover that was partially or fully bleached (0-100%; e.g. 5% bleached cover). If NULL, see CoralBleached_Bin.

Identification of cluster that the survey level data was grouped into (if data was used in analysis). Spatial auto-correlation was reconciled by performing hierarchical clustering to group survey data into distinct clusters with a spatial resolution of 1km. The data was stratified across depths to generate metrics for up to three depth bins per cluster: shallow (0-6m), mid (>6-18m), and deep (>18m).
