“They would never mention underwater volcanoes, I guess..?” says reader.
“The Norwegian Met Office has posted an article about the heating of Barents Sea, being colder than average in the upper layers but unusually warm at the bottom,” says reader Flemming K. Sørensen in
Denmark . “They don’t know the reason, and guess it’s caused by warm water coming from the Atlantic Ocean. They would never mention underwater volcanoes, I guess..?”
Although surface water in the Barents Sea is colder than last year, it’s warmer at the bottom, says the article.
Temperature readings by Norwegian and Russian scientists done in conjunction with the annual ecosystem survey show that the Barents Sea is warmer at the bottom than last year, especially in the western parts, says Randi steward, head of IMR research on climate and fish.
The cause is not completely known, but “it is probably related to the supply and flow of warm Atlantic water to these areas (which) has been higher than usual.”
“(Or) is probably related to the large-scale wind field, such as trade winds, prevailing westerlies, polar jet stream and the east wind.
Luckily, the warmer water is not necessarily a threat to fish and marine mammals.
On the contrary, the Atlantic water is warm and rich in nutrients and plankton, thus providing better conditions for fish such as cod and capelin.
Of course there are also fish in the Barents Sea not so happy about it being warmer, “but it is hardly a threat to them.”
Southeast of the Barents Sea, one must return to the 1950s to find higher measured temperatures.
I don’t know if there are underwater volcanoes in the Barents Sea or not, but I think Mr. Sørensen is onto something. How else would you heat the bottom of the ocean before you heat the surface?
