Dear colleagues, On behalf of my co-authors, I am pleased to announce our new publication in Marine Mammal Science. Kobayashi, H., Ikuta, S., & Kobayashi, M. (2023). First aerial observation of Sato's beaked whales (Berardius minimus) above the Abashiri Submarine Canyon, Hokkaido, Japan. Marine Mammal Science, 1–8 (Early view). https://doi.org/10.1111/mms.13099 On May 8, 2023, we found three groups of whales that appeared to be Sato's beaked whales around the Abashiri Submarine Canyon, Hokkaido, Japan, and successfully captured aerial videos using UAVs. In this paper, representing the first of its kind, we describe the external morphology of these whales in images captured by UAVs. A digest of the aerial videos captured during this survey is available on the YouTube channel of the Tokyo University of Agriculture. https://youtu.be/XNtY4p1t_5o?si=w7wsXNzDBhVv1IAi Best regards, Hayao Kobayashi Tokyo University of Agriculture ********************************************************** Kobayashi Hayao Ph.D. Tokyo University of Agriculture Department of Ocean and Fisheries Sciences Postdoctoral researcher 196 Yasaka, Abashirishi, Hokkaido, 099-2493, Japan.
