Reprocessed multi-channel seismic-reflection data set from the Arctic Ocean, collected using icebreakers between 2007-2011 and 2014-2016 for the Canadian Extended Continental Shelf program / J. Shimeld,... : M183-2/8850E-PDF

"Upon ratifying the United Nations Convention on the Law of the Sea in 2003, the Government of Canada needed information from seismic reflection data to define the outer limits of its Extended Continental Shelf in the Arctic Ocean. Staff at the Geological Survey of Canada collected these data using a seismic system designed for deployment on the icebreaker Louis S. St-Laurent during eight expeditions in 2007-2011 and 2014-2016. These expeditions were managed by three federal government departments (Natural Resources, Fisheries and Oceans, and Global Affairs) and involved multiple operational collaborations with the United States, Denmark and Sweden. The work produced 157 seismic reflection lines with a combined track-length of 18622 km, offering abundant information about the crust and overlying sedimentary succession across previously unexplored regions of the Arctic Ocean basin. The data are released both as SEG-Y standard binary files and PNG standard raster images. Signal processing is applied in a consistent manner using specialized techniques developed through accumulated experience with various noise-types caused by the icebreaking operations. Users can browse the seismic data in geographical and geological context using the provided map-based interface, which is run on a standard web-browser"--Provided by publisher.
