Polar Acoustics and Oceanography

Group Leader: 
Hanne Sagen


About us

Take a leading role in the development, implementation and scientific use of a Pan Arctic Ocean Observing System

Research Objectives

Carry out fundamental acoustic research for applications within sea ice research, oceanography, environmental monitoring, underwater communication and geo-positioning.

Carry our fundamental oceanographic research for improved estimates of the heat, mass, and freshwater fluxes and storage in the sparsely sampled Arctic region by combining direct measurements with numerical models. Acoustic remote sensing provides one of the few ways to observe the abyssal ocean.

Improve the understanding of small and meso-scale ocean processes and their importance for the large-scale ocean climate system by combining new observation technologies, platforms, and models.
