Northeast Atlantic

ROCCA classifiers for the Northeast Atlantic - process clicks and whistle contours detected using PAMGuard’s Whistle & Moan Detector and Click Detector to classify seven delphinid species.

Northeast Atlantic Classifier

When used together to classify encounters containing multiple vocalizations, these ROCCA classifiers performed with an overall accuracy of 78%, ranging from 60% for Grampus griseus encounters to 92% for Orcinus orca encounters. The following seven species can be identified:

  • Atlantic white-sided dolphin (Lagenorhynchus acutus)
  • Common bottlenose dolphin (Tursiops truncatus)
  • Killer whale (Orcinus orca)
  • Long-finned pilot whale (Globicephala melas)
  • Risso’s dolphin (Grampus griseus)
  • Short-beaked common dolphin (Delphinus delphis)
  • White-beaked dolphin (Lagenorhynchus albirostris)

Models

Northeast Atlantic ROCCA click and whistle classifiers can be found on Zenodo: zenodo.org/records/14936662. Separate click and whistle predictions are intended to be combined for final species classification via an R application (see README file) also accessible through the Zenodo download. Also included in the download are a PAMGuard settings file (.psfx) for ROCCA and a README file in the download containing documentation, tutorials, and extra information.
