* » 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. |

100 | No | No | Shape | GEOMETRY | Indicates the type of geometry (Polyline), automatically generated in ArcGIS. |
100 | No | No | DIVEID | NUMBER | Unique ID/9-digit serial number for each 50-minute survey.

100 | No | No | SEGMENTID | NUMBER | Unique ID/11-digit serial number for each 5-minute survey segment/observation. The serial number is formed by concatenating the DIVEID with the 2 digit segment number (01-10). The segment number sequence restarts each survey and is restricted to values 01-10.

Description |
The mean combined temperature (in degrees Celsius) recorded by the SeaBird SBE39 units mounted on the fish and benthic towboards, averaged over the 300 5-second readings made during the 5-minute towed-diver survey segment. 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. |

Description |
The length (in meters) of each 5-minute towed-diver survey segment 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 SEGMENTID. 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. |

Description |
The length (in meters) of each 5-minute towed-diver survey segment 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. |
