This is the OBIS extraction of the Ocean Tracking Network and University of Washington (UWash) Essington Tags, 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.\n 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=NEP.ESS).\n
Abstract:The Pacific Ocean Shelf Tracking (POST) project was designed to develop and promote the application of acoustic tagging technology to study the life history of Pacific salmon and other species migrating along the continental shelf of western North America. POST envisioned the eventual creation of a permanent continental-scale telemetry system, however, during its existence more limited pilot-scale arrays were deployed, primarily concentrated in the Pacific Northwest. These included several acoustic receiver curtains between Vancouver Island and the mainland, creating an excellent means by which to monitor coastal marine animal migrations, especially by juvenile salmonids (smolts) migrating to sea (see projects QCS, JDF and NSOG). In addition to arrays on the continental shelf, POST equipment was deployed upstream and in the estuaries of several major salmon-producing rivers. POST arrays, and POST data, were incorporated into the OTN in 2012. The integration of these arrays, their equipment and the associated animal tagging projects into OTN's global network allowed for international, widespread monitoring of important species within the Northeast Pacific Ocean. Tracking data generated from the POST arrays can be applied to the development of fishery management policies aimed at the sustainable harvest of resources, and to the understanding and conservation of other marine and diadromous species. Additional details about specific tracking projects which were originally a part of POST are only available by contacting the associated researcher.

Acoustic receivers arranged in line on the ocean floor as well as attached to buoys, gliders and large animals (e.g. grey seals) pick up the coded acoustic signals from these tags identifying each tagged sea creature that passes within half a kilometer of the receiver. Data collected by these listening stations are subsequently uploaded to one of many compatible data nodes, adding to the reach of an intercompatible network of networks designed and maintained by the Ocean Tracking Network, producing current and reliable records for every part of the globe. Certain classes of electronic tags and listening equipment (receivers) may also be outfitted or co-located with sensors to measure the ocean's temperature, depth, salinity, currents, chemistry, and other properties.","relatedProjects":[],"abstract":"The Pacific Ocean Shelf Tracking (POST) project was designed to develop and promote the application of acoustic tagging technology to study the life history of Pacific salmon and other species migrating along the continental shelf of western North America.
