Description
Summary:History of documentation of fin whales in the Kitimat Fjord System. (A) Reported kills from the whaling records, not corrected for effort; (B) sightings reported to the BC Cetacean Sightings Network, not corrected for effort; (C) effort-corrected encounter rates (fin whales detected per kilometer of track line surveyed) for three boat-based research platforms, 2004–2015 (note different y-axis scales); (D) effort-corrected detection rates (fin whales detected per hour of scan effort) of fin whales from three shore-based research stations, 2010–2019. Note that shore-based detection rates are for demonstration purposes only; they were not used to assess annual trends in relative abundance.
