This is the OBIS extraction of the Ocean Tracking Network and South African National Parks (SANParks) Shark Spotters shark tracking, 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=SAF.SSST).
Abstract:Broadnose sevengill sharks (Notorynchus cepedianus) are apex predators that have a global distribution in the shelf and coastal waters of temperate seas. A limited number of studies have assessed the demography and movement patterns of sevengills. Acoustic and satellite telemetry have also been used to provide more detailed insights into the behaviour, fine scale movements and habitat usage of sevengills in certain areas, including south-east Tasmania and the north-west Pacific. In both areas movement patterns ranged from seasonal aggregations in coastal areas such as bays and estuaries, to long distance (>400 km) coastal migrations. However the drivers behind these patterns in movement are largely unclear, and may be related to reproductive behaviour, seasonal shifts in prey abundance and distribution, or environmental factors such as changing water temperatures. The primary aim of this research is to investigate the behaviour and movement patterns of broadnose sevengill sharks, both on a fine scale in False Bay, and more broadly along the South African coast. This knowledge will be used to improve our understanding of distribution, population connectivity, patterns of residency, site fidelity and migration for this species, with the overarching objective of improving management and conservation strategies to ensure the sustained presence of this important apex predator in the coastal ecosystems they inhabit.

| 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 |
Описание этапа методики:
- 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.
