Invited Lecture

The Southern Ocean is one of the most diverse soundscapes of earth. The dynamics of the cryosphere i.e. sea ice, glaciers and icebergs create unique acoustic conditions. During polar winter the snow covered sea ice shields the ocean from atmospheric influences, suppresses the creation of waves and resembles an almost perfect acoustic absorber, thus creating one of the quietest environments of...

20. Looking for spaghetti in a haystack: Semiautomatic approaches to detecting marine mammals in highly variable noise environments

Invited Lecture

The wide variety of sounds produced by marine mammals are for the most part well documented. While some of these sounds, such as fin whale moans and the clicks of harbour porpoise and beaked whales are highly stereotyped, others, such as humpback song and dolphin whistles are highly variable both at the individual and at the population level. Even the more stereotyped sounds can become highly...

21. Look who’s talking – classification of whale sounds using the Whale FM Citizen Science project

Alexander von Benda-Beckman (WhaleFM/TNO)

Invited Lecture

Long term acoustic monitoring, which is required for assessing impact of anthropogenic activities on marine mammals, leads to increasingly large acoustic datasets that need to be classified. Although significant improvements have been made in applying automated methods to categorize marine mammal calls, scientists often still have to rely on human judgment to classify calls into call...
