Tows

Sequential unique whole numbers that are automatically generated.

Indicates the type of geometry (Polyline), automatically generated in ArcGIS.

Unique ID/9-digit serial number for each 50-minute survey. The serial number is formed by concatenating the 4-digit survey year, 2-digit month, 2-digit day, and dive/tow survey number of the day (1-6). The dive number sequence restarts each day and is restricted to values 1-6. For example, the DIVE ID for the first dive on March 13, 2011 is 201103131.

4-digit year the survey was conducted.

4-letter region code for the geographic region (archipelago) in which the survey was conducted.

AMSM: American Samoa

MARI: Guam and Commonwealth of Northern Mariana Islands

MNHI: Main Hawaiian Islands

NWHI: Northwestern Hawaiian Islands

PRIA: Pacific Remote Island Areas

3-letter island code for the island at which the survey was conducted. Full name of each island code is listed in the Island_Lookup_Table.csv.

The mean temperature (in degrees Celsius) recorded by the SeaBird SBE39 mounted on the fish towboard averaged over the 3000 5-second readings made during the 50-minute towed-diver survey. From 2000 to 2009, in most cases the average temperature from the fish and benthic SBE39s is only provided in CTEMP_MEAN, unless the data from a specific time period was reprocessed with a newer version of the Python script (and therefore the mean temperature is provided for both the fish and benthic as well as the combined). All zero values represent NULL values and not measured values due to a limitation of the shapefile format. All NULL values were converted to zero when the source geodatabase feature class was exported to shapefile format. No zeros exist in the source dataset.

If the SBE39 failed to record temperature data for the majority of the 50-minute survey, this field is left blank.

The length (in meters) of each 50-minute towed-diver survey calculated by the track processing script in Geodesic (unprojected) space. This is the arc length of each survey based on a spherical earth model. It is calculated by adding up the geodesic distance between each of the 5-second survey points, grouped by DIVEID. All zero values represent NULL values and not measured values due to a limitation of the shapefile format. All NULL values were converted to zero when the source geodatabase feature class was exported to shapefile format. No zeros exist in the source dataset.

Latitude in decimal degrees, WGS84, for the center point of each 50-minute towed-diver survey.

Longitude in decimal degrees, WGS84, for the center point of each 50-minute towed-diver survey.

The length (in meters) of each 50-minute towed-diver survey calculated by the data manager using ArcGIS, based on the UTM projection for the location of the survey. This is a manual calculation made in ArcGIS after the initial track processing has been completed. Coordinate System = UTM Zone projection appropriate for each survey region, Units = meters. All zero values represent NULL values and not measured values due to a limitation of the shapefile format. All NULL values were converted to zero when the source geodatabase feature class was exported to shapefile format. No zeros exist in the source dataset.
