Description
This is the OBIS extraction of the OTN Gilbert Bay Telemetry 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: Understanding the movement and dispersal of marine animals is an important aspect of marine ecology, and has important resource management applications including the ability to assess and manage Marine Protected Areas effectively. Gilbert Bay, Labrador, was designated as an MPA under Canada's Oceans Act in 2005. Since then the movements of Atlantic cod and other species have been monitored remotely using a network of acoustic telemetry receivers. Since 2009, remote monitoring has consisted of approximately 35 receiver stations covering an area of approximately 330 square kilometres, including Gilbert Bay, Alexis Bay, and a section of the south Labrador coast. Manual tracking has been conducted in this area since 1997. This long-term acoustic monitoring program has also detected animals from other acoustic tagging studies, including Atlantic salmon and Atlantic cod. This small receiver network, located within a sub-arctic ecosystem, is a potentially valuable contribution to the larger OTN network. This is a SPERA project dataset.

| Financement | 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'. |
| Description du domaine d'étude / de recherche | 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. |
| Description du design | 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. |

Méthodes d'échantillonnage
Acoustic receivers were deployed and acoustic tags were released.
| Etendue de l'étude | Tagging program started in 2005 and is ongoing. |
|---|---|
| Contrôle qualité | 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. |
