Description
To better understand the ecological function of large marine carnivores in continental-shelf ecosystems, grey seals will be fitted with a novel acoustic technology (VEMCO mobile transcievers) and Agros satellite-linked tags to investigate spatial and temporal patterns of prey encounters and 2) predator movements and foraging distribution in relation to fine- and meso- scale seasonal oceanography in eastern Canada. The OBIS collection is a subset of this dataset containing species presence distribution information (no abundance or biomass estimates). more

Predator-prey interactions have important population and community level consequences that depend on the frequency of predator and prey encounters. How pinnipeds and other large marine predators exploit the patchy distribution and abundance of prey is poorly understood because it is difficult to measure the relevant variables by direct observation. To better understand the ecological function of large marine carnivores in continental-shelf ecosystems, grey seals will be fitted with a novel acoustic technology (VEMCO mobile transcievers) and Agros satellite-linked tags to investigate spatial and temporal patterns of prey encounters and 2) predator movements and foraging distribution in relation to fine- and meso- scale seasonal oceanography in eastern Canada. The OBIS collection is a subset of this dataset containing species presence distribution information (no abundance or biomass estimates). This OBIS product reports the tagging/release of these seals. Though there have been detections by OTN (Ocean Tracking Network) acoustic receivers, these are currently being used for in-progress research. This dataset is the OBIS version of the grey seal tagging. These data are for display on the OBIS portal and associated mapping programs and for download for end-user analysis The following reports on the OBIS schema fields provided for in this dataset: Res_Name, DateLastModified, InstitutionCode, CollectionCode, CatalogNumber, ScientificName, Latitude, Longitude, BasisOfRecord, YearCollected, MonthCollected, DayCollected, TimeOfDay,TimeZone, ObservedIndividualCount, FieldNumber, Collector, JulianDay, Locality, Sex, LifeStage, ObservedWeight, ObservedLength, Kingdom, Phylum, ClassName, OrderName, Family, Genus, Subgenus, Species, Subspecies, Notes (AphiaID: value + Notes).
