The marginal ice zone is the dynamic border between the open sea and the sea ice, which is ecologically extremely vulnerable. The phytoplankton present in the sea produces half of the oxygen on the planet. During spring, this zone is the most important CO2 sink in our biosphere. In Spring Bloom in the Marginal Ice Zone the sounds of the living creatures become a voice in the current political debate concerning the official definition of the location of the ice edge.
The listener experiences the bloom of plankton, the shifting and crackling sea ice in the Barents Sea around Spitsbergen, towards the North Pole, and the underwater sounds made by bearded seals, migrating species such as humpbacks and orcas, and the sound made by hunting saithe, crustaceans and spawning cod, all depending on the spring bloom.
Spring Bloom in the Marginal Ice Zone is a Sonic Acts and Dark Ecology commission first shown as a 7 channel installation at the Sonic Acts festival (Muziekgebouw, Amsterdam, 2017). It was supported by Art & Technology - Arts Council Norway, Fond for lyd og bilde, Tono stipendet, ARCEx research cruise on R/V Helmer Hanssen, UiT The Arctic University of Norway.

CARLOS M. DUARTE is Professor of Marine Science, Tarek Ahmed Juffali Research Chair in Red Sea Ecology, Biological and Environmental Science and Engineering Division, and is a world-wide leader in multiple branches of biological oceanography and marine ecology.
PHILIPP ASSMY is a researcher at The Norwegian Polar Institute, Tromsø, Norway. Current activities include species-specific studies of planktonic and sympagic communities and primary productivity in the Arctic Ocean north of Svalbard. He is also studying the impact of changing sea ice conditions and associated effects (e.g. changes in light climate and surface stratification) on phytoplankton and ice algal communities.
