Fungi help lock carbon into Arctic fjord sediments

Arctic fjords are among the most efficient natural systems for absorbing and storing carbon long term. However, as the Arctic is warming about four times faster than the global average, fjord ecosystems are changing rapidly. Against this backdrop, understanding the biological processes that regulate carbon storage is becoming increasingly important. Yet the microbial mechanisms that control whether carbon is stored in sediments or returned to the environment are still not fully understood.
