This is the OBIS extraction of the Ocean Tracking Network and Department of Fisheries and Oceans Canada (DFO) DFO: Porbeagle and Blue Sharks, consisting of the release tagging metadata, i.e. the location and date when the tagged animal was released, and summarized detection events of tagged individuals. If readers are interested in the source dataset they may also inquire with the project PIs as listed here or on the OTN web site (https://members.oceantrack.org/project?ccode=JPBS). Abstract:To determine movements of porbeagle and blue sharks in Canadian waters and to see if they cross over the US/Canadian border to American waters. The data would help with future management of both species.
