OTN Bras d'Or Lakes Array - Tag Release Metadata

Latest version published by Ocean Tracking Network on Feb 20, 2019 Ocean Tracking Network

This is the OBIS extraction of the OTN Bras d'Or Lakes Array project, consisting only of the release tagging metadata. i.e. the locations and dates of tagged animal release. If readers are interested in the full source dataset they should refer to the OTN web site (members.oceantrack.org). Abstract: The Bras d'Or Lakes Array will use OTN theory and technology to determine the ecological connections between Canada's inland sea (the Bras d'Or estuary of Cape Breton), its watershed, the Scotian Shelf, the Gulf of Saint Lawrence and the NW Atlantic Ocean. The intent is to fully instrument the sites of exchange between the major river catchements of the watershed and the estuary, the channels linking the major basins of the estuary, and all channels of exchange between the estuary and the surrounding ocean. Motile anadromous, catadromous, and marine species of significance (e.g., Atlantic salmon, American eel, Atlantic cod) will be acoustic tagged in rivers, bays, banks, and basins of the Bras d'Or to track their movements within the estuary and its watershed, and between the estuary and the surrounding OTN arenas of the NW Atlantic Ocean. The Bras d'Or Lakes Array will be located throughout the Bras d'Or estuary, including all channels connecting the estuarine waters to those of the surrounding ocean, the channels connecting the major basins of the estuary, and the mouths of the main rivers flowing into the estuary. The initial array is composed of 15 stations. An additional 11 sites are proposed for subsequent years, depending on the results obtained during the first tagging experiments.

Data Records

The data in this occurrence 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 98 records.

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.

Project Data

No Description available

Title Ocean Tracking Network (OTN)
Funding OTN is a $168-million research and technology development initiative headquartered at Dalhousie University, in Halifax Nova Scotia. Starting in 2008, OTN began deploying Canadian state of the art acoustic receivers and oceanographic monitoring equipment in key ocean locations. These are being used to document the movements and survival of marine animals carrying acoustic tags and to document how both are influenced by oceanographic conditions. OTN is funded by the 'Canada Foundation for Innovation' and the 'Natural Sciences and Engineering Research Council of Canada' with additional support from 'Dalhousie University' and the 'Social Sciences and Engineering Research Council of Canada'.
Study Area Description OTN is a project of the Global Ocean Observing System (GOOS) providing infrastructure to collect comprehensive data on sea animals in relation to the ocean's changing physical properties at strategic locations along the sea floor in 14 ocean regions off all seven continents. OTN data are in the process of being routinely copied to International Oceanographic Data Exchange (IODE) recognized facilities at the Department of Fisheries and Ocean Canada for long term sustainability and to the Ocean Biogeographic Information System (www.obis.org) for public accessibility.
Design Description A wide range of aquatic species - salmon, tuna, whales, sharks, penguins, crabs, and seals, to name a few, are tagged with small electronic transmitters, surgically implanted or attached externally, and 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 are subsequently uploaded to a central database, resulting in current and reliable global records that can be analyzed and applied to many different environmental research efforts. Tags and receivers are also be outfitted with sensors to measure the ocean's temperature, depth, salinity, currents, chemistry, and other properties.

The personnel involved in the project:

Principal Investigator
Sara Iverson

Sampling Methods

Acoustic receivers were deployed and acoustic tags were released.

Study Extent Tagging program started in 2012 and is ongoing.
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.
