A comparison of historical oceanographic data from the Arctic Ocean with that obtained aboard the CCGS Louis s. St. Laurent during the Canada/U.S. 1994 Arctic Ocean Section unequivocally shows that the mid-depth layers of the Arctic Ocean are experiencing a major warming and ventilation event. The intrusion of new water is characterized by (a) higher values in the Atlantic Layer maximum temperatures, (b) a shallower core depth for the temperature maximum, (c) displacement of waters of Pacific origin in the upper 100-200m, and (d) pronounced thermohaline inversions 40-60m thick in the Atlantic Layer and Upper Deep waters. The largest temperature change, as much as 1℃, is seen in the core of the Atlantic Layer, suggesting that the event is related to an increase in the transport and/or temperature of water entering from the North Atlantic.
