DESCRIPTION:Marine mammals\, which include whales\, dolphins and porpoises
  (cetaceans)\, together with sirenians\, seals\, walruses and a number of 
 other creatures\, all spend most of their time in the sea. Living their li
 ves in the water\, they have not only adapted their lifestyles\, but have 
 also modified the way in which they interact with each other and with the 
 environment. In particular\, cetaceans’ sound generation and auditory sy
 stems have evolved to base their daily life mainly on acoustics. Like bats
 \, they use sound in the way we use light to both communicate and to inves
 tigate the environment. Apart from being essential for these animals\, thi
 s use of sound allows human researchers to eavesdrop and to study cetacean
  behaviour from a distance. This talk explores how (and why) marine mammal
 s can be detected\, identified and localised using techniques developed by
  the military for Anti Submarine Warfare and based on the mathematics inhe
 rent in three academic disciplines:\n•	Underwater Acoustics \n•	Signal
  Processing\n•	Ecology\nThis is generally referred to as Passive Acousti
 c Monitoring (PAM).\n
