Switchyard Project: Tracking the Arctic Seascape

Arctic summer sea ice is declining rapidly: a trend with enormous implications for global weather and climate. The multi-year Arctic Switchyard project will seek to distinguish the effects of natural climate variability from those of human-induced climate change.
