| Summary | (Plain Language Summary, not published)
The 2018041 CCGS Hudson expedition was a joint mission between the Geological Survey of Canada (Atlantic) and the Nova Scotia Department of Energy and
Mines (NSDEM). Past expeditions (2015018 and 2016011-PH2) on the Scotian Slope led to evidence of cold seeps on the seafloor and the presence of gas hydrates. The objectives of expedition 2018041 were to target several sites on the Scotian Slope with
the purpose of collecting high resolution seabed imagery using Autonomous Underwater Vehicle (AUV) and towed instruments (bathymetry, sub-bottom profiles, sidescan, video, photos) and samples (gravity cores, box cores) in order to better understand
cold seep and sediment transport processes. |
