Primary key for the data table.

Mission identifier: NOAA Ship, 2-digit federal fiscal year, 2-digit mission number for the fiscal year.

HA/HI = NOAA Ship Hi'ialakai

OES = NOAA Ship Oscar Elton Sette

TC = NOAA Ship Townsend Cromwell

Shore = shore-based survey launch

The name of the region surveyed in the Pacific Islands region: American Samoa, Pacific Remote Island Areas, Mariana Archipelago, main Hawaiian Islands, Northwestern Hawaiian Islands.

Name of island or atoll surveyed in the Pacific Islands region (REGION_NAME).

4-digit year the survey was conducted (DATE_).

Date of the tow survey. dd-MMM-yy

Normal = standard towed diver survey (not a calibration survey).

The reef zone for the given towed diver segment (Forereef, Backreef, Lagoon, unspecified).

Forereef: The sloping bottom underlying the wave break zone, extending seaward from the reef crest. Comprehensive surveys of forereef habitats remain the priority for towed-diver operations.

Backreef: The shallow strip of reef sheltered from breaking waves by the reef crest, situated between the reef crest and the lagoon floor.

Lagoon: The zone sheltered from the waves by the reef crest, and separated from the reef crest by the back reef. Usually deeper than the back reef and covered in unconsolidated sediment, this term describes both an atoll's interior and the expanse situated between the back reef and shore of any islands present.

Unspecified: these are other areas surveyed using towed-diver methods, which include bank (a submerged platform reef, often occurring either as an isolated feature atop a seamount or as a plateau situated between the fore reef and a deeper slope) and channel (a submerged transition between forereef and backreef zones created by a gap in the reef crest).

Unique key for the given tow (DIVEID).

Unique ID representing 4-digit year, 2-digit month, 2-digit day, and tow number of day (1-6).

Unique ID representing 4-digit year, 2-digit month, 2-digit day, tow number of day (1-6), and SEGMENT number (01-10).

Segment number for a given tow. Segments represent 5-minute increments and there are typically, but not always, 10 segments per tow.

Mean depth in meters of the towed diver during the 5-min observation (SEGMENT). May be null if the SEABIRD failed or if the instrument data could not be synced with the GPS or observation data.

Mean temperature in degrees Celsius during the 5-min observation (SEGMENT). May be null if the SEABIRD failed or if the instrument data could not be synced with the GPS or observation data.

Local starting date and time of the 5-min observation (dd-MMM-yy hh:mm:ss). Start and stop time is not consistently provided.

Local ending date and time of the 5-min observation (dd-MMM-yy hh:mm:ss). Start and stop time is not consistently provided.

Latitude in decimal degrees, WGS84, for the midpoint of the given 5-min SEGMENT.

Longitude in decimal degrees, WGS84 for the midpoint of the given 5-min SEGMENT.

Calculated length of SEGMENT in meters using GIS.

4-letter code for TAXONNAME.

Scientific name of observed organism to the finest taxonomic resolution that divers can identify.

Number of organisms observed for the given SEGMENT.

Length of organism, reported in centimeters. In some cases the size of exceptionally large (i.e., whales) or partially hidden (i.e., eels) organisms may not be provided.

Taxonomic classification: Phylum of observed organism (TAXONNAME).

Taxonomic classification: Class of observed organism (TAXONNAME).

Taxonomic classification: Order of observed organism (TAXONNAME).

Taxonomic classification: Family of observed organism (TAXONNAME).

Common name given for the FAMILY (used for grouping purposes during data analysis). For example, Dolphin, Monk Seal, and Turtle, among others.

Taxonomic classification: the true scientific name (genus and species) of the observed organism (TAXONNAME). If NULL, organism not identified to species taxonomic level.

Common name of the organism (TAXONNAME). If NULL, organism not identified to species taxonomic level.
