說明

This is the OBIS extraction of the OTN Canada Sable Island Grey Seal Bioprobes 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: Objectives are to better understand the ecological function of large marine carnivores in continental-shelf ecosystems, using grey seals as our model species and novel acoustic technology developed for OTN. There are two components: 1) spatial and temporal patterns of prey encounters by a mobile, large marine predator, and 2) predator movements and foraging distribution in relation to fine- and meso- scale seasonal oceanography in eastern Canada. The first study will contribute to science advice on the impact of pinniped predation on the dynamics of prey populations of commercial or conservation importance. The second study seeks to understand the oceanographic features that grey seals may use to condition the way they search the environment for food and in turn predict how climate variability and long-term change may affect upper-trophic level predators and alter their impact on continental shelf ecosystems.

計畫名稱 Ocean Tracking Network (OTN)
經費來源 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'.
研究區域描述 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.
研究設計描述 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.

取樣方法

Acoustic receivers were deployed and acoustic tags were released.

研究範圍 Tagging program started in 2009 and is ongoing.
品質控管 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.
