Earth scientists at CAGE together with colleagues from The Geological Survey of Norway and Akvaplan-niva aim to assess the role of Arctic gas hydrate in past, present and future climate change. For past or present reconstructions we study samples from the sub seabed, the seabed, the water column and the atmosphere and for the future outlook we aim to use modeling with experts from atmospheric science. To accomplish these goals, CAGE contributes to enhanced collaborations and relationships with university and industry research teams at national and international levels.
