Typically, cold waters of Hudson Bay ice-covered from January to May. Completely ice cap melts only in the middle of August. But this year, in early April in the Gulf experienced strong ice flow. In many parts of the Hudson River, especially in the east of the Gulf of St. James and Hudson Strait, which leads to the Atlantic Ocean, one can see clearly the areas of water filled with ice shards. Also on the ice throughout the eastern half of the Hudson are cracks and splits.

According to the National Center for Research of ice and snow, the Arctic ice reached its maximum size is 18 March. From that day in the northern hemisphere, the early spring, and the period of melting snow and ice has accelerated. According to experts in this layer of ice was somewhat thicker than in previous winters, however, are still below average. The maximum amount of ice was also registered later than usual. This means that the new ice formed in the season, too thin and will melt faster.
Something similar is happening in the Hudson. According to the Canadian observation services, despite the fact that the overall level of the Bay of melting ice does not come out of the ordinary, in the east of the process occurs too rapidly. There rasstayal already 90 and in some places 100% of frozen water. Closer to the central west coast of the ice volume has decreased by 60-80%. Throughout its history the Hudson does not remember such indicators.
Abnormalities in the concentration of ice.
Also reported an increase in water temperature in almost all parts of the bay. In Coral Harbour near Southampton Island in the north of the Hudson, the temperature of April 9 to 10 ° C above normal. This warm water is only accelerates the process of melting ice. What is this if not a consequence of global warming? ..
