Processed ship-based Navigation Data (version 2) from the Southern Ocean acquired during the Nathaniel B. Palmer expedition NBP1310B (2013-2014) and NBP1409 (2014)
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 NBP1310B nd NBP1409 Primary Navigation data (quality version 2) downloaded from the Marine GeoScience Data System (MGDS)
Marine Geoscience Data System (MGDS): NBP1310B
Marine Geoscience Data System (MGDS): NBP1409
- 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

| Dataset-specific Description | This data set was acquired with a ship-based Navigation system |
| Generic Instrument 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. |

Global climate change is having significant effects on areas of the Southern Ocean, and a better understanding of this ecosystem will permit predictions about the large-scale implications of these shifts. The haptophyte Phaeocystis antarctica is an important component of the phytoplankton communities in this region, but little is known about the factors controlling its distribution. Preliminary data suggest that P. antarctica posses unique adaptations that allow it to thrive in regions with dynamic light regimes. This research will extend these results to identify the physiological and genetic mechanisms that affect the growth and distribution of P. antarctica. This work will use field and laboratory-based studies and a suite of modern molecular techniques to better understand the biogeography and physiology of this key organism. Results will be widely disseminated through publications as well as through presentations at national and international meetings. In addition, raw data will be made available through open-access databases. This project will support the research and training of two graduate students and will foster an established international collaboration with Dutch scientists. Researchers on this project will participate in outreach programs targeting K12 teachers as well as high school students.
