A time-lapse camera was mounted to take images monitoring beluga and vessel activity in the Churchill River estuary during July - September 2020. Images taken between August 13 and 28, 2020, were used for a study on beluga response to tourism vessels. Photos were corrected for puncission lens distortion using the Pentax filter in Photoshop 21.2.0. Details on the location of the camera can be found in the publication.

The data here was used in the following paper:

Ausen, E. L., Marcoux, M., Chan, W. S., & Barber, D. G. (2022). Beluga (Delphinapterus leucas) response to personal watercraft and motorized whale watching vessels in the Churchill River estuary. Frontiers in Marine Science, 9, 837425.

This data page also includes the pixel location data from photos, and the code for analysis.
