Abstract
Broad-scale acoustic telemetry networks are being established worldwide. The 10-year anniversary of the
Integrated Marine Observing System’s Animal Tracking Facility provided the opportunity to assess the efficiency of one of
the first national-scale acoustic telemetry networks. Acoustic networks are comprised of acoustic receiver arrays that detect
high-frequency transmitters attached to animals that pass within detection range. Herein we assessed the efficiency of eight
curtains to detect passing animals by calculating the standardised mean number of detections and transmitters detected at
each station. The aim was to determine how many receivers could be decommissioned from each curtain while maintaining
its integrity (i.e. detection of all species passing the array). Pivotal locations were defined as the furthest station at which all
species would still be detected and where at least 75% of the detections and transmitters would still be detected. By applying
these criteria, we were able to improve the cost-effectiveness of our network significantly, reducing the number of stations
from 132 to 85 (64% of the original network), yet still retaining 84% of total detections, 86% of transmitters and 100% of
detected species. The present study provides a useful framework for refining acoustic telemetry networks.
