Processed ship-based Navigation Data (version 2) from the Southern Ocean acquired during the Laurence M. Gould expedition LMG1312 (2013)This data set was acquired with a ship-based Navigation system during Laurence M. Gould expedition LMG1312 conducted in 2013 (Chief Scientist: Dr. Kenneth Halanych). These data files are of MGDS:Nav format and include Primary Navigation data and were processed after data collection. Funding was provided by NSF grant(s): ANT10-43745.

| 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. |

| Description | Benthic invertebrate studies |
Extracted from the NSF award abstract:
The research will explore the genetics, diversity, and biogeography of Antarctic marine benthic invertebrates, seeking to overturn the widely accepted suggestion that benthic fauna do not constitute a large, panmictic population. The investigators will sample adults and larvae from undersampled regions of West Antarctica that, combined with existing samples, will provide significant coverage of the western hemisphere of the Southern Ocean. The objectives are: 1) To assess the degree of genetic connectivity (or isolation) of benthic invertebrate species in the Western Antarctic using high-resolution genetic markers. 2) To begin exploring planktonic larvae spatial and bathymetric distributions for benthic shelf invertebrates in the Bellinghausen, Amundsen and Ross Seas. 3) To continue to develop a Marine Antarctic Genetic Inventory (MAGI) that relates larval and adult forms via DNA barcoding.
