The Arctic Ocean includes various basins, each with its own specific characteristics and rate of warming. The process of Atlantification<\/a> in the Arctic Ocean – the process where the Arctic Ocean becomes more influenced by the warmer, saltier waters of the Atlantic – is well-known<\/a>.<\/p>\n However, a new study has found that the deep water in the Eurasian Basin of the Arctic Ocean is warming at a rate of 0.020\u00b0C per decade. According to the researchers, this rate of warming is too fast to be explained by natural geothermal heating\u00a0alone.<\/p>\n \u201cOur findings indicate that the deep Greenland Basin warming has already exerted obvious impacts on the deep Arctic Ocean,\u201d researchers emphasise.\u00a0<\/p>\n The Greenland basin is\u00a0a deep-water basin within the Greenland Sea, which is considered an outlying part of the Arctic Ocean and borders Greenland to the west.<\/p>\n The team concluded that the additional warming in the Eurasian Basin originates from the Greenland Basin, which, due to rapid warming, is no longer functioning as a cold source for the Eurasian Basin as it did in the past.<\/p>\n “We find that the rapid warming in the deep Greenland Basin diminishes its cooling effect on the deep Eurasian Basin via the Fram Strait,” the study concludes.<\/p>\n The shallow Lomonosov Ridge prevents the warm water from spreading further into the Amerasian basin, “maintaining its relatively slow warming rate”.<\/p>\n For Norway, for example, the warming of the coastal waters is impacting the local ecosystem. According to experts at the Norwegian Institute of Marine Research, warmer waters affect the spawning of cod. <\/p>\n “Some species have absolute temperature limits. Cod, for instance, cannot spawn when the temperature exceeds 10 degrees,’ said <\/a>marine scientist Mari Myksvoll.<\/p>\n Fishermen in the Arctic have reported an increase in the number of fish that are more typical of southern waters. <\/p>\n
