Abstract: This dataset includes track locations of geophysical data collected as part of research cruises conducted by, or for, the Geological Survey of Canada (Atlantic). Geophysical data types collected on AANDC (Aboriginal Affairs and Northern Development Canada) supported BREA (Beaufort Regional Environmental Assessment) cruises include "light" reflection pinger-type seismics (Knudsen 3.5 kHz), and multibeam sonar bathymetry. Track locations were taken at anywhere from 30 to 5 second intervals. The supplied shapefile includes all BREA - related Expeditions (cruises). BREA - specific expeditions are limited to numbers 2009804, 2010804, 2011804 and 2014804. Research cruise ship navigation data are collected and archived in order to show where the Geological Survey of Canada (Atlantic) have conducted seabed surveys and to provide a reference location as well as the kinds of geophysical data collected during those surveys. This data is available on an expedition by expedition basis via a similar PDC GSC entry but also provided in a generic GIS format (shapefile) here. Generally, 3.5 kHz sub-bottom sounder and multibeam bathymetric soundings were conducted along these expedition tracks.
