The recent identification of the bio-duck call as Antarctic minke whale (AMW) vocalization allows the use of passive acoustic monitoring to retrospectively investigate year-round spatial- temporal patterns in minke whale occurrence in ice-covered areas. Here, we present an analysis of AMW occurrence...
