Methods & Sampling

Dataset acquisition description

Processed ship-based Navigation Data (version 2) from the Southern Ocean acquired during the Nathaniel B. Palmer expedition NBP1302 (2013)

This data set was acquired with a ship-based Navigation system during Nathaniel B. Palmer expedition NBP1302 conducted in 2013 (Chief Scientist: Dr. Dennis Hansell). These data files are of ASCII format and include Primary Navigation data and were processed after data collection. Data were acquired as part of the project(s): TRACERS.

Processed ship-based Navigation Data (version 2) from the Southern Ocean acquired during the Nathaniel B. Palmer expedition NBP1302 (2013)
This data set was acquired with a ship-based Navigation system during Nathaniel B. Palmer expedition NBP1302 conducted in 2013 (Chief Scientist: Dr. Dennis Hansell). These data files are of ASCII format and include Primary Navigation data and were processed after data collection. Data were acquired as part of the project(s): TRACERS.

Quality 2 - The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).

BCO-DMO Processing Notes
- Generated from NBP1302 Primary Navigation data (quality version 2) downloaded 4 February 2015 from the Marine GeoScience Data System (MGDS)
- Awk routine generated to reformat original files into BCO-DMO servable file format
- Awk routine: "MGDS_Nav_2_CruiseTrack.awk"
- Parameter names generated to conform to BCO-DMO naming convention found at Choosing Parameter Name
- Date/Time reformatted to ISO DateTime format
- Cruise Id added to data
- SOG and COG values not reported in original files
- SOG and COG (both set to 0.0) added to each data record for compatibility with other BCO-DMO cruise track datasets

Instruments

Global Positioning System Receiver

Supplied Name: Trimble GPS - PCODE

Supplied Description:

This data set was acquired with a ship-based Navigation system

Instrument Type

Generic Name: Global Positioning System Receiver

Acronym: GPS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/POS03/

Generic Description:

The Global Positioning System (GPS) is a U.S. space-based radionavigation system that provides reliable positioning, navigation, and timing services to civilian users on a continuous worldwide basis. The U.S. Air Force develops, maintains, and operates the space and control segments of the NAVSTAR GPS transmitter system. Ships use a variety of receivers (e.g. Trimble and Ashtech) to interpret the GPS signal and determine accurate latitude and longitude.
