These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

These data contain point files that include information related to navigation, vehicle attitude, the environment, and vehicle status. The processed point data was converted into ArcInfo format and cleaned of fliers. Line coverages were constructed from the point files. Purpose: These data were created to aid in the desription and discovery of the workings of the hydrothermal vent system found on the Endeavour Segment of the Juan de Fuca Ridge.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: Chain-node topology. Logical_Consistency_Report: The locational information for these data are related to positional accuracy. Completeness_Report: Navigational data were analyzed for erroneous fixes, i.e. points that were obvious outliers were removed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were logged by the DSRV Alvin using an in-hull navigation system. This system uses the travel time of accoustic energy from the submersible to the transponders and back to the submersible (rather than submersible-transponder-ship). The accuracy is +/- 1.0 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical control was provided by the pressure sensor and altimeter readings on the submersible. The vertical accuracy is +/- 0.5 meters.

The submersible was navigated with a long-baseline transponder net. The sub's position was monitored by surface controllers and by the pilot and scientists in the sphere with the in-sub program. 2. Positions were reported in ALVIN X/Y (meters) coordinates based on a grid which has its origin at 47.8939 degrees latitude and -129.16451667 degrees longitude (to the south and west of the transponders and dive region for each transponder net). 3. ALVIN positions were then converted into Lat/Long measurements with the program "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin). 4. Data were then entered into GIS.
