Summary

Abstract

Segments is a polyline shapefile and it is generated during data processing of the geospatial and SBE39 data. The data represent the estimated survey track of the divers for each 5-minute segement of a towed-diver survey. The data is generated by processing the DivePoints using a track processing algorithm, lacing together each of the 5-second survey points, and grouping them by SegmentID.

Description

Data table for Segments shapefile from the towed-diver surveys.

Description:

The standard deviation of temperature (in degrees Celsius) recorded by the SeaBird SBE39 mounted on the benthic towboard averaged over the 300 5-second readings made during the 5-minute towed-diver survey segment. From 2000 to 2009, in most cases only the average temperature from the fish and benthic SBE39s is provided in CTEMP_MEAN, and therefore the standard deviation of the temperature was provided only in CTEMP_STDE, unless the data from a specific time period was reprocessed with a newer version of the Python script (and therefore the temperature standard deviation is provided for both the fish and benthic as well as the combined).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.

Null Value Meaning:

If the SBE39 failed to record temperature data for the majority of the 5-minute survey segment, this field is left blank.
