Processed ship-based Navigation Data from the Antarctic Peninsula acquired during the Laurence M. Gould expedition LMG0414 (2004)
This data set was acquired with a ship-based Navigation system during Laurence M. Gould expedition LMG0414 conducted in 2004 (Chief Scientist: Dr. Kenneth Halanych). These data files are of Text File (ASCII) format and include Navigation data and were processed after data collection. Data were acquired as part of the project(s): Relevance of planktonic larval despersal to endemism and biogeography of antarctic benthic invertebrates and Salpa thompsoni in the Southern Ocean: Bioenergetics, population dynamics and biogeochemical impact, and funding was provided by NSF grant(s): ANT03-38218 and ANT03-38290.

BCO-DMO Processing notes:
- downloaded and served the primary navigation data from IEDA: http://www.marine-geo.org/tools/search/Files.php?data_set_uid=23561

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.
