BK Salmon in warm waters – Terrace Standard


Anomaly or the new norm, the researchers carefully monitor the constant flow of water in the Pacific Ocean and the salmon.

During the last two months BS The high-pressure ridge that has appeared on the coast of the coast has been extended to the summer. The noise season was late, and the water cried to 2-3 degrees Celsius.

Dr. Ocean Networks Canada, Richard Dewey, and Victoria University have carefully monitored the 2000 km long, autumnal area in the autumn of 2013, and was observed in spring 2014. researchers have created the term "blob".

"This story has wakened us to what's going on here. Combined with the atmosphere, blizzards and flowing streams, we are getting winds blowing over the stern, so we do not mix cold water, and everything is warm, "says Dewey.

Now they pay attention. By 2017, oceanographers begin to drastically increase the heat, but this year in the Pacific and the Bering Sea.

"Perhaps this is a trend. Perhaps climate change is visible in the backyard, but we do not know yet, "says Dewey.

Ocean Networks is located on the bottom of Canada and on the ocean coast. In some months, researchers have drawn closer attention to satellite data and sea temperature maps for the Alaska Bay.

The effect of salmon

Heating on the ocean affects the temperature of fresh water.

Sue Grant – State Program for Fisheries and Ocean Canopies Canada (DFO). Its role is to combine knowledge of salmon and ecosystems. Oceanographers and freshwater explorers see the interconnection of blocks and heat in rivers and streams.

"The bloc itself is called an oceanographic phenomenon, but it affects the atmospheric contact and pure water," said Grant.

Salmon is clean water, fresh water and marine life cycles and they feel warm in both habitats. According to the grant, the impact of the blocks in 2014 and 2015 and the territory of Yukon.

"The answers are interrupted but our southern reserves and some of our northern parts do not work well this year. Last year, we have seen low-end species of Fraser Waterhouse salmon and this year we've come back from the average survivors in Fraser. There are other examples in the north, "he said.

The grant uses marathon analogy to describe the seasonal temperature above 3-5 degrees.

If he spends a marathon at 50 degrees Celsius, he may not survive because it is outside the optimum temperature range of 50-60 degrees Celsius. The salmon possesses an optimum temperature range, and can be adversely affected when migrating to high-altitude peaks during the summer.

It affects the level of nutrients as well as the average water temperature.

When the ecosystem changed in 2014-2015, the Alaska Bay surface was weak in nutrients. Ocean Networks in Canada has found that cold water types require a nutrient-rich environment, while the prevalent warm water types are adapted to low nutritional conditions.

"The salmon is eaten in the desert and on the shore, where they come back in 2016-17, less than usual," says Dewey.

"The numbers I have seen, this year, allow for a reduction in the amount of fish, and this also affects them."

According to Grant and Dewey, they draw their attention, but predict what the salmon will be for the salmon in 2018.

However, over the last few years, salmon can be used for the warming of freshwater and marine ecosystems – and the clock to know what patterns are available for the saline of the salmon.
