Description

This is the OBIS extraction of the Ocean Tracking Network and Dalhousie University (DAL) OTN NS Blue Shark Tracking, 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.

Abstract:In the Northwest Atlantic, the Ocean Tracking Network (OTN), in collaboration with Dalhousie University, is using an acoustic telemetry infrastructure to monitor the habitat use, movements, and survival of juvenile blue sharks (Prionace glauca). This infrastructure includes state-of-the-art acoustic receivers and oceanographic monitoring equipment, and autonomous marine vehicles carrying oceanographic sensors and mobile acoustic receivers. Long-life acoustic tags (n=40) implanted in the experimental animals will provide long-term spatial resolution of shark movements and distribution, trans-boundary migrations, site fidelity, and the species’ response to a changing ocean. This study will facilitate interspecific comparisons, documentation of intra- and interspecific interactions, and permit long-term monitoring of this understudied predator in the Northwest Atlantic. The study will also provide basic and necessary information to better inform fisheries managers and policy makers. This is pertinent given the recent formulation of the Canadian Plan of Action for Shark Conservation.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 8,449 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

  • Event (core)
    8449
  • Occurrence 
    6768
  • ExtendedMeasurementOrFact 
    510

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Title Ocean Tracking Network Nova Scotia Blue Shark Tracking
Funding OTN is a research and technology development initiative headquartered at Dalhousie University, in Halifax Nova Scotia. OTN is funded by the Canada Foundation for Innovation (CFI) and is grateful to have once received funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Social Sciences and Engineering Research Council of Canada (SSHRC). OTN is also grateful for the continued support from Research Nova Scotia, and OTN's host institution, Dalhousie University.
Study Area Description No study area description for this project was provided to OTN for publication.
Design Description A wide range of aquatic species are tagged with small electronic transmitters, surgically implanted or attached externally, which can operate for up to 20 years. 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.

Sampling Methods

Acoustic tags released.

Study Extent Program started 2013-01-01 and ran until None
Quality Control OTN species names are verified using the World Register of Marine Species (WoRMS). If species names on new data cannot be verified against (a) known valid names in OTN, and/or (b) WoRMs the Data Provider will be notified so they can check they are correct. Names that cannot be placed after checking with WoRMS are, where possible, placed on the basis of other authoritative sources, such as the Fishbase or ITIS; and once completely verified a request will be sent to WoRMS for addition of the verified species name. http://members.oceantrack.org/data/discovery/byspecies

Method step description:

  1. This resource was created by the Ocean Tracking Network Data Centre as a summarized representation of animal presence determined by electronic tagging efforts. Darwin Core (DwC) records were extracted from the OTN database and filtered and summarized according to international agreed-upon standards.
