Abstract
Acoustic detcetions of odontocetes from over 30,000km of survey effort from
the Arctic, Atlantic, Southern and Indian Oceans, using a streamlined
workflow for increasing the speed of acoustic anakysis for large datasets
utilizing existing modules within PAMGuard.

Supplemental information
Each record represents species presence only.
Records of "SONAR" were dropped.
Survey trackline is provided as a static image online.
