Active acoustic data from Kongsfjorden, Svalbard

Acoustic instruments mounted on automated surface vehicles provide high spatial and temporal resolution sampling of the pelagic realm. This dataset was collected to document the spatial and vertical distributions and migrations of zooplankton and fish in a period poorly document in high-Arctic fjords, the polar night. Data are provided in raw format from the instrument and can be read using acoustic processing softwares and/or routines (http://www.aslenv.com/AZFP-data.html) or programming softwares (e.g. Matlab, R).This project is associated with the 'Arctic Ocean ecosystems - Applied technology, Biological interactions and Consequences in an era of abrupt climate change (Arctic ABC) program that is funded by the Norwegian Research Council (project # 244319).
