Dr. Barry Margrave, a marine ecologist with the Department of Fisheries and Oceans, analysed the lipid-soluble chemicals—such as PCBs and organochlorine pesticides—that had accumulated in the amphipods' fatty tissue. Amphipods were collected using baited traps, much like those used for crab and lobster, on the ocean floor. To position the traps, the Bedford Institute of Oceanography in Dartmouth, , custom-built a portable electric winch for use during the Scientific Ice Expeditions (SCICEX) program.
