Cook Inlet Beluga Aerial Photogrammetry


Aerial view of Cook Inlet beluga whales.

Location: Cook Inlet

Timing: August - September

Funding: NOAA

Project: Photogrammetry surveys will be conducted to estimate age classes and an index of beluga calf production in late August/early September. A hexacopter UAS equipped with a high-resolution camera will be used to photograph beluga groups. Individuals will be measured to provide blowhole to dorsal ridge lengths, and whales will be assigned to calf, juvenile, and adult age classes based on relative lengths.
