Описание

This is the OBIS extraction of the Ocean Tracking Network and Department of Fisheries and Oceans Canada (DFO) TOPPWS, 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=NEP.TOPPWS).

Abstract:Gaining insights into seasonal aggregations of marine megafauna and how patterns vary among demographic groups is pivotal for modeling populations and ecosystem dynamics and evaluating anthropogenic risk exposure. In California, adult and sub-adult white sharks recurrently aggregate on the central coast in fall and winter months, while juveniles are thought to remain present in southern aggregations year-round. However, understanding of movements outside of known aggregation sites, transitions in patterns between ontogenetic groups, and drivers of presence at coastal sites is limited. Using a long-term acoustic tagging program (established in 2006) in Central California, our project focuses on unraveling the coastal movement patterns of white sharks spanning juvenile to adult size ranges. Our expanded receiver array covers both historical aggregation sites and additional locations along the Central California coast, providing a finer-scale investigation into shark movements.

Финансирование 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.
Описание района исследования No study area description for this project was provided to OTN for publication.
Описание плана выполнения исследований 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.

Контроль качества 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
