Detailed circulation and stratification features from an Arctic observing system

We present high-resolution space-time dependent observations of circulation and stratification features in the Chukchi Sea, Arctic Ocean from an observing system consisting of AUV gliders, HF radars, drifters, and sub-surface moorings. These unique high-latitude observations show a more complex, dynamic and high-energy ocean environment than previously reported in the Arctic. We also present examples of imminent technology needs for high-latitude areas.
