Description
This is the OBIS extraction of the Ocean Tracking Network and Emera Inc. (Emera) OTN VR2W Loan - Emera Snow Crab and American Lobster, 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. 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=V2LEMERA).
Abstract:The NSP Maritime Link Inc. (NSPML) [operating as Emera Newfoundland and Labrador (ENL)], a wholly owned subsidiary of Emera Newfoundland and Labrador Holdings Inc., is constructing a 500 megawatt (MW) [+/- 200 kilo volts (kV)] high voltage direct current (HVdc) and high voltage alternating current (HVac) transmission line, and associated infrastructure, between Granite Canal, Newfoundland and Labrador (NL), and Woodbine, Nova Scotia (NS) (the Maritime Link). The Project includes two 170 kilometer long subsea cables spanning the Cabot Strait from Point Aconi (NS) to Cape Ray (NL). As part of the Environmental Assessment (EA) for the Project, the potential environmental effects of the installation and operation of these cables were assessed and, with the implementation of the design and mitigation measures, determined to be not significant. Consistent with commitments and conditions of the EA release NSPML initiated an Environmental Effects Monitoring Program for two resident commercially harvested marine species, snow crab (Chionoecetes opilio) and American lobster (Homarus americanus), to confirm that once operational the subsea cables will not have an adverse impact on the movement of benthic species. The current study tracks the movements of snow crabs and American lobster in their natural habitat before and after the installation and energisation the submarine cables. This will allow for the characterization of the animals’ behaviour and the identification of any changes.
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 834,414 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.
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.

The NSP Maritime Link Inc. (NSPML) [operating as Emera Newfoundland and Labrador (ENL)], a wholly owned subsidiary of Emera Newfoundland and Labrador Holdings Inc., is constructing a 500 megawatt (MW) [+/- 200 kilo volts (kV)] high voltage direct current (HVdc) and high voltage alternating current (HVac) transmission line, and associated infrastructure, between Granite Canal, Newfoundland and Labrador (NL), and Woodbine, Nova Scotia (NS) (the Maritime Link).

| 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. |

| Study Extent | Program started 2014-10-20 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:
- 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.
