NBP0101 Seismic:Active:Subbottom
Shapefiles associated with processed sub-bottom data from the East Antarctic Margin during 2001 Palmer cruise NBP0101
This sub-bottom data set was collected with an ODEC Bathy2000 hull-mounted sub-bottom CHIRP system in 2001 during Palmer cruise NBP0101 (chief scientist Amy Leventer). These are shapefiles created from groups of hourly SEG-Y files that were lightly processed and clumped into groups spanning approximately 12 hours. See the accompanying sub-bottom data processing report for details. The primary purpose of the cruise was to investigate the relatively unexplored East Antarctic continental margin, from the Wilkes Land region to the Mac.Robertson shelf, searching for, and sampling, high resolution sedimentary records. The data set was created as part of the project called Quaternary Glacial History and Paleoenvironments of the East Antarctic Margin. Funding was provided through NSF awards OPP01-96389, OPP99-09367, OPP99-09793, OPP99-09837.
