Description
Summary:Raw seismic reflection sub-bottom data collected with a towed Edgetech 512i CHIRP sub-bottom profiler from Scripps Institution of Oceanography. The data files are in SEG-Y format and contain real-time GPS navigation in the header. The CHIRP towfish included a pressure sensor, allowing the depth of the towfish to be taken into account. As a result, the two-way travel time in the raw CHIRP data is referenced from the sea surface not the towfish. The data set was collected in 2013 in the Beaufort Sea during Healy cruise HLY1302 (investigators Lloyd Keigwin and Neal Driscoll) as part of the project titled "Collaborative Research: Testing the Northern Route for Younger Dryas Meltwater". Funding was provided by NSF awards OPP12-04045, OPP12-03944 and PLR12-04112.
