Summary(Plain Language Summary, not published)
The 2018 042 cruise of CCGS Hudson studied areas of satellite mapped oil slick features off Cape Dyer, Baffin Island. Water measurements at two of five locations show very high amounts of dissolved methane very near the seafloor. Sediment samples are currently being analysed to identify the origin of the methane in the sea water. Use of an unmanned aerial vehicle (UAV) from ship was successfully demonstrated but attempts to identify oils slicks with a standard video camera failed. High levels of dissolved methane near the seafloor are confirmed over an area of 30 km.
