During my PhD I lead a field campaign, AZKABAN-light (Arrested Zooplankton Kept Alive for Broadband Acoustic Net light experiment) during which we built a purpose-built mesocosm species for acoustic experiments in Ny-Ålesund, Svalbard during the polar night in January 2022. Fieldwork collaboration with Chelsey McGowan-Yallop and Stig Falk-Petersen. Photo taken by Malin Daase.

The conservation objectives of the Anguniaqvia niqiqyuam Marine Protected Area (ANMPA) focus on maintaining the integrity of marine habitats offshore of the Cape Parry Migratory Bird Sanctuary that support populations of key species, such as beluga whales, Arctic Char, and ringed and bearded seals. This report provides ecosystem-level scientific knowledge to support the development of monitoring objectives and activities.

This paper presents the inverse method applied to broadband autonomous acoustic surveys. We conclude the inverse method can improve density estimates of epipelagic organisms by diminishing avoidance biases and increasing the spatio-temporal resolution of ship-based surveys.

Teacher’s assistant for enriched physics lab classes for first-year bachelor students. The students explored physics and statistical analysis through experiments and coding. I insturcted and guided students to an understanding of physics through socratic questioning. I marked lab assignments and provided feedback.
