Bellwethers of change: population modelling of North Pacific humpback whales from 2002 through 2021 reveals shift from recovery to climate response.

For the 40 years after the end of commercial whaling in 1976, humpback whale populations in the North Pacific Ocean exhibited a prolonged period of recovery. Using mark-recapture methods on the largest individual photo-identification dataset ever assembled for a cetacean, we estimated annual ocean-basin-wide abundance for the species from 2002 through 2021. Trends in annual estimates describe strong post-whaling era population recovery from 16 875 (± 5955) in 2002 to a peak abundance estimate of 33 488 (± 4455) in 2012.

Radio Documents: Broadcasting, Sound Archiving, and the Rise of Radio Studies in Interwar Germany.

This article investigates the relationship between broadcasting, sound archiving, and the rise of radio studies through the case of Germany's first radio studies institute, led by linguist Friedrichkarl Roedemeyer at the University of Freiburg from 1939 to 1945. I outline an emergent notion of radio research starting in the early 1920s, which contributed to a concept of radio content as both documentation and commodity object. The work of Wilhelm Doegen at the Lautabteilung ("sound department") in Berlin proved key to the development of radio research based on archival documentation, recording media, and multidisciplinary research agendas.

Capturing commemoration: Using mobile recordings within memory research.

This paper details the contribution of mobile devices to capturing commemoration in action. It investigates the incorporation of audio and sound recording devices, observation, and note-taking into a mobile (auto)ethnographic research methodology, to research a large-scale commemorative event in Amsterdam, the Netherlands. On May 4, 2016, the sounds of a Silent March-through the streets of Amsterdam to Dam Square-were recorded and complemented by video grabs of the march's participants and onlookers.
