Support for the deployment and operation of the gliders was provided by the Marine Environmental Observation Prediction and Response Network (MEOPAR) Whales, Habitat and Listening Experiment (WHaLE), the Ocean Tracking Network (OTN), Natural Sciences and Engineering Research Council of Canada (NSERC), Fisheries and Oceans Canada (DFO), the World Wildlife Federation (WWF), and Canadian Steamship Lines (CSL). MEOPAR-WHaLE is supported by 20 collaborating organizations. Support for the development, integration, and testing of the glider DMON/LFDCS was provided by the U.S. Office of Naval Research and the NOAA National Marine Fisheries Service Advanced Sampling Technologies Working Group in collaboration with the Northeast Fisheries Science Center's Passive Acoustics Research Group (leader: Sofie Van Parijs)."
