Article Synopsis
- During the gray whale migration from late 2014 to early 2015, researchers used acoustic calls, infrared technology, and visual sightings to estimate whale populations.
- The average gray whale call rate was about 7.5 calls per whale per day, peaking during the migration, allowing for the estimate of 4,340 whales migrating south before visual observations began.
- To improve future studies, it's suggested to increase survey efforts throughout December and utilize multiple infrared cameras tailored for various distances offshore, as detection rates varied significantly by location.
