Identification of soundscape components and their temporal patterns in Kongsfjorden, Svalbard Archipelago
Time series measurements of ocean ambient sound were carried out using an autonomous passive acoustic measurement system deployed in Kongsfjorden, Arctic Ocean, between July 2015 and April 2016. Geophysical soundscape components, particularly that of sea ice melting and wind noise, were identified....
