Abstract

This is the OBIS extraction of the OTN Kintama Research Services: Seymour River steelhead smolts. 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: Fifty Seymour River steelhead smolts were double-tagged with VEMCO V9 and V4 acoustic transmitters, and then released in Malaspina Strait (east side of Texada Island in the Strait of Georgia) to migrate over acoustic arrays in the Salish Sea. The V9 transmitters allowed us to estimate early-marine survival through the northern Strait of Georgia and Discovery Islands, and provided a baseline estimate against which to evaluate the detection performance of the V4 transmitter (VEMCO’s newest, smallest transmitter). Cumulative survival over the ~170 km from release to Johnstone Strait was 46% (SE=7.0%).   Detection efficiency of the V4 was 74% (SE=10%) at the Discovery Island subarray compared to 100% for the V9 tags. Since the subarray was fully functional and the tags were operating within their warranted lifespan, we consider this to be a useful first estimate of what can be achieved with the V4 tags.An animation of the movements of the Seymour River steelhead smolts released in 2015 is available on our website (http://kintama.com/visualizations/).

Project details

Project title: Ocean Tracking Network (OTN)
Personnel: Sara Iverson
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 descriptions/descriptor: 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.

Methods

Method step description: This resource was created by OTN data management for publication at OBIS. Darwin Core (DwC) records were extracted from the core OTN database in the required IPT format.
Study extent description: Tagging program started in 2015, ending in 2015
Sampling description: Acoustic tags released.
Quality control description: 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.
