Passive Acoustic Monitoring (PAM) in the Southern Ocean: three generations of autonomous recorders in a basin wide array
Passive acoustic monitoring (PAM) has emerged as a highly efficient technology to conduct long-term monitoring of marine mammals at species dependent, local to basin scales, providing valuable new insights into species distributions and migration patterns. To study Antarctic mammals, we deployed up...
