“…While a variety of acoustic metrics and indices are available (BradferLawrence et al, 2019), the intention of this study was to utilize the figurative "lens" of soundscape power (Kasten et al, 2012) and NDSI (Gage and Axel, 2014) to describe the current state of the Aialik Bay coastal wilderness. Soundscape power has been successfully used to describe soundscapes in southcentral Alaska (Mullet et al, 2016(Mullet et al, , 2017a and coastal soundscapes in the Pacific Northwest (Ritts et al, 2016). Although NDSI has not yet been applied to subarctic ecosystems, NDSI is based on the metric of soundscape power (normalized watts/kHz) so it was expected that NDSI could be a useful descriptor as it has been in other studies (Gage and Axel, 2014; Fuller et al, 2015; Eldridge et al, 2016; Schindler et al, 2020.…”
