Atlantic Cooperative Telemetry (ACT) Network is a collaborative telemetry infrastructure that integrates acoustic tagging, receiver arrays, and shared databases to study marine animal movement, behavior, and ecology across the western Atlantic seaboard. The network coordinates researchers, institutions, and resource managers to enable large-scale studies of fish, sharks, turtles, and marine mammals using interoperable technologies and standardized data protocols. ACT facilitates cross-institutional collaborations among universities, government agencies, and non-governmental organizations to address conservation, fisheries, and climate-related questions.

History and Development

ACT emerged from regional acoustic telemetry collaborations inspired by early tagging programs at Scripps Institution of Oceanography, Woods Hole Oceanographic Institution, University of Miami Rosenstiel School of Marine and Atmospheric Science, and Dalhousie University that followed technological advances developed by companies and labs associated with Vemco, Lotek Wireless, The Ocean Tracking Network, Tagging of Pacific Predators (TOPP), Global Ocean Observing System, Integrated Ocean Observing System, and initiatives funded by National Science Foundation and Natural Sciences and Engineering Research Council of Canada. Early pilots involved multi-institutional arrays in regions such as the Gulf of Maine, Chesapeake Bay, Gulf of Mexico, and Caribbean Sea and drew participants from agencies including NOAA Fisheries Service and Fisheries and Oceans Canada as well as university labs at Duke University, University of Florida and Stony Brook University.

Formalization of ACT consolidated protocols, metadata standards, and data-sharing agreements influenced by models from Ocean Biogeographic Information System, Global Biodiversity Information Facility, Data Observation Network for Earth and policy frameworks advocated by Convention on Biological Diversity, Commission for the Conservation of Antarctic Marine Living Resources, and regional fisheries management bodies.

Network Structure and Technology

ACT operates through a distributed architecture combining acoustic receiver arrays, mobile hydrophone deployments, autonomous surface vehicles, and centralized databases. Hardware vendors and technology partners include Vemco, Lotek, Sonotronics, Advanced Telemetry Systems, Oceanscience, Teledyne Marine and sensor platforms developed at Woods Hole Oceanographic Institution and Scripps Institution of Oceanography. Array deployments leverage moorings charted near landmarks such as the Gulf Stream, Georges Bank, Nantucket Shoals, Chesapeake Bay Bridge–Tunnel, Cape Hatteras, Florida Keys National Marine Sanctuary, and Banco Chinchorro.

Network software and data standards align with platforms and initiatives like Ocean Tracking Network, Tagging and Tracking of Marine Animals (TATMA), Global Ocean Observing System, Environmental Sensor Data Standards (ESDS), Global Biodiversity Information Facility, Obis (Ocean Biogeographic Information System), DataONE, GEOSS, and engineering contributions from university groups at Massachusetts Institute of Technology, Princeton University, University of California San Diego, Imperial College London, ETH Zurich.

Data Collection and Management

ACT collects detection records from tagged individuals using acoustic transmitters attached to species studied at institutions such as University of North Carolina at Chapel Hill, University of California Santa Cruz, Texas A&M University, Louisiana State University, University of the West Indies, Universidad de Puerto Rico Río Piedras Campus, University of the Azores, University of Havana, and Universidad del Valle. Species monitored include populations studied by researchers at Florida Museum of Natural History, Smithsonian Tropical Research Institute, Monterey Bay Aquarium Research Institute and New England Aquarium such as sharks tagged following protocols from Shark Trust, sea turtles tagged in programs connected to Sea Turtle Conservancy, and commercially important fish tracked in collaborations with Atlantic States Marine Fisheries Commission, Gulf of Mexico Fishery Management Council, and NOAA Fisheries.

Data management integrates cataloguing and curation influenced by the Global Biodiversity Information Facility, Ocean Biogeographic Information System, DataONE, and institutional repositories at Dalhousie University Libraries and Woods Hole Open Access Server with metadata standards compatible with Darwin Core and persistent identifiers from DataCite.

Research Applications and Findings

ACT-enabled studies have produced findings on migration corridors, residency, mortality, spawning site fidelity, and habitat use across biogeographic regions including North Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and Bermuda. Research outputs appear in journals published by Nature Conservation, Proceedings of the Royal Society B, Marine Ecology Progress Series, ICES Journal of Marine Science, Journal of Experimental Marine Biology and Ecology, Conservation Biology, Ecological Applications, Frontiers in Marine Science, PLoS ONE, Scientific Reports, and Journal of Fish Biology. Findings have informed management advice to bodies such as Atlantic States Marine Fisheries Commission, NOAA Fisheries, Gulf of Mexico Fishery Management Council, South Atlantic Fishery Management Council, and influenced conservation actions supported by The Nature Conservancy and World Wildlife Fund.

Collaborative projects have illustrated connectivity between nursery grounds and adult habitats, documented responses to oceanographic features like the Gulf Stream and Loop Current, and demonstrated distribution shifts linked to climatic drivers studied under programs associated with Intergovernmental Panel on Climate Change, NOAA Climate Program Office, and NSF Long-Term Ecological Research.

Governance, Funding, and Partnerships

Governance combines steering committees with representation from universities, governmental agencies, and NGOs including NOAA, Fisheries and Oceans Canada, Atlantic States Marine Fisheries Commission, The Nature Conservancy, Smithsonian Institution, and major funders such as National Science Foundation, Natural Sciences and Engineering Research Council of Canada, Packard Foundation, Gordon and Betty Moore Foundation, Monterey Bay Aquarium’s David and Lucile Packard Foundation grants, National Fish and Wildlife Foundation, and regional philanthropies. Partnerships extend internationally to institutions like University of Lisbon, Universidade de São Paulo, University of the West Indies, University of Puerto Rico, Australian Institute of Marine Science, and Japan Agency for Marine-Earth Science and Technology for comparative studies.

Data-sharing policies are informed by practices from Global Biodiversity Information Facility and legal frameworks that intersect with national statutes administered by United States Fish and Wildlife Service, Environment and Climate Change Canada, and regional fishery councils.

Challenges and Future Directions

Challenges include funding sustainability debated in forums such as Society for Conservation Biology and American Fisheries Society, technological interoperability amid vendor ecosystems dominated by Vemco and Lotek, and balancing open data advocates aligned with Open Knowledge Foundation against jurisdictional restrictions overseen by agencies like NOAA and Fisheries and Oceans Canada. Future directions emphasize integration with satellite telemetry programs pioneered by Argos, environmental DNA initiatives from groups at Scripps Institution of Oceanography and Monterey Bay Aquarium Research Institute, coupling with oceanographic observing networks such as Argo, NOAA Integrated Ocean Observing System, and expansion into regions underrepresented in current arrays including the southern Caribbean and West Africa in collaboration with Universidade de Cabo Verde and University of Ghana.

ACT aims to enhance species conservation through improved connectivity analyses, real-time detection alerts for stranding and bycatch mitigation in coordination with Marine Stewardship Council and International Union for Conservation of Nature, and to support climate resilience research linked to assessments by the Intergovernmental Panel on Climate Change.
