Changing Arctic Carbon cycle in the Coastal Ocean Near-shore (CACOON): a new project on the changing Arctic coast
No other region has warmed as much or as rapidly in the past decades as the Arctic. A new project, CACOON, will investigate how the ecosystems are influenced by this warming. Funded by the British Natural Environment Research Council (NERC) and the German Federal Ministry of Education and Research (...

No other region has warmed as much or as rapidly in the past decades as the Arctic. A new project, CACOON, will investigate how the ecosystems are influenced by this warming.
