Methods & Sampling

Processed ship-based Navigation Data from the Amundsen Sea, Antarctica acquired during the Nathaniel B. Palmer expedition NBP0901 (2009)
This data set was acquired with a ship-based Navigation system during Nathaniel B. Palmer expedition NBP0901 conducted in 2009 (Chief Scientist: Dr. Stan Jacobs). These data files are of MGDS:Nav format and include Primary Navigation data and were processed after data collection. Data were acquired as part of the project(s): Collaborative International Research: Amundsen Sea Influence on West Antarctic Ice Sheet Stability and Sea Level Rise, Shedding dynamic light on iron limitation: The interplay of iron limitation and dynamic irradiance conditions in governing the phytoplankton distribution in the Ross Sea, and Collaborative Research: Sampling the ocean - sea ice interaction in the Pacific center of the Antarctic Dipole, and funding was provided by NSF grant(s): OPP06-32282.

Data Processing Description

Quality 1 - A level of processing has been undertaken, ensuring quality control (e.g. ping edited sonar data, edited navigation data).

BCO-DMO Processing Notes
- Generated from NBP0901 Primary Navigation data (quality version 2) downloaded 6 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: GPS

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.

Parameters

Date and time formats are described in python strftime() syntax.
