Radical transformation of the Pacific Arctic Includes Impacts to Freshwater

Scientists from multiple agencies, working collaboratively to supply data to the Arctic Integrated Ecosystem Research Program, are detecting rapid changes in the Bering and Chukchi Seas. These changes are driven by abnormally high water temperatures and rapid loss of sea ice (on par with climate predictions for 2040), and include high numbers of Pacific cod and pollock expanding into Arctic waters, higher concentrations of harmful algal blooms, and a sea bird die-off that began in 2014 impacting puffins, common murre and, most recently, short-tailed shearwaters. At the base of the food web, larger, high-fat copepods are declining while smaller, copepods with a lower-fat content are flourishing. This means less nutrition for Arctic cod, while, at the same time, more competition for these resources as pollock expand their range northward.

But these troubling changes are not limited to northern ocean waters. Inland, freshwater rivers in the Arctic are overheating. Record-warm temperatures in July, 2019 caused heat stress and a mass die-off in returning, pre-spawned salmon. Read more.

Unprecedented Numbers of Pink Pacific salmon are showing up in the Arctic

In the latest indication of the rapidly warming waters in the western Arctic, Pink salmon were recently caught in the western Nunavut waters of Cambridge Bay. According to Karen Dunmall, an aquatic biologist with Fisheries and Oceans Canada, due to diminishing sea ice, Pacific salmon have been following food sources, which include plankton to jellyfish, shrimp and smaller fish. This is another indication that climate change, which results in thinner sea and fresh water ice that forms later and breaks up earlier, warmer rivers, milder winters, longer summers and changes in wildlife and vegetation, is affecting the Arctic more dramatically than anywhere on the globe. It’s n across the Arctic

In total, the Arctic research salmon program estimates that in 2019 roughly 2,000 salmon samples have been provided to them – almost triple the number from 19 years of monitoring harvesters and this number appears to be rising.

Similarly, Pink salmon have spread to parts of northern Europe after being released into rivers in Russia in the 1960s. Unprecedented numbers of the fish were found in Scottish rivers in 2017 and they were seen again in 2019 on the Dee which flows through Aberdeenshire, the Tweed which passes through the Borders, Kyle of Sutherland which is an estuary in the east Highlands and the River Ness which flows through Inverness and into Loch Ness when in September, a lone male was captured on one of our underwater surveillance cameras.”

Fishery managers in Scotland are concerned that the Pinks which are voracious eaters and which have already become established in rivers and streams in Norway, could colonize Scottish rivers and out compete native Atlantic .

Talking up Resilient Arctic Water Infrastructure in Nevada

What was I doing in the plush Nugget Casino in the 90 degree heat of Sparks, Nevada last month talking about improving Water Infrastructure through Resilient Adaptation of Alaska Native Village Communities in the North Bering Sea region? Because while the room full of water Geeks attending the summer specialty conference of the American Water Resources Association, were familiar with all the news coverage about super hurricanes and flooding on the east coast, they probably were not that familiar with the plight of communities in the North Bering Sea region (NBSR) of Alaska who are dealing with similar threats to their water infrastructure.

Arctic communities are have been experiencing increased permafrost melt, loss of sea ice, extreme weather events, flooding and erosion that may make current residences and settlements uninhabitable in the near future. Such communities have another thing in common with coastal cities on the east coast-they are in direct competition for limited federal disaster and hazard mitigation funding to defend against the inevitable march or climate change. In many cases, for example, agencies require cost-benefit analysis, plans, environmental analysis, or other measures above and beyond analysis or strategies contained in Hazard Mitigation Plans (HMPs) or other plans before such communities qualify to apply for funds. Similarly, because standard arctic community HMPs do not contain a detailed cost-benefit analysis of natural hazards affecting water resources, such communities cannot obtain high rankings that larger cities can to qualify for competitive funding or other federal or state assistance needed to address such impacts. Finally, the villages cannot afford to hire consultants or even staff to conduct climate adaption planning on behalf of such communities to include more meaningful consideration of economic impacts and risks associated with coastal water resource management resiliency strategies, in order to move beyond the planning phase and into on the ground project implementation.

During my talk at the conference, therefore, I emphasized the need to conduct economic risk-benefit and environmental analysis and otherwise close the gap between Federal Emergency Management Agency (FEMA) and other governmental funding and technical assistance programs such so that North Bering Sea communities can implement on-the-ground projects that will address the Villages’ climate-related coastal water resources management challenges. Hopefully, word will travel to the ears of these agencies so that tribes in the Arctic can move behind the planning phase and into project implementation…something the needs to happen…yesterday.

 

The Trump administration continues its push for offshore Arctic oil development

Secretary of the Interior David Bernhardt and Secretary of Commerce Wilbur RossIn U.S. District Court in Anchorage recently, filed notice that they are appealing the March 29 ruling that threw out Trump’s executive action reopening closed Arctic and Atlantic waters to oil leasing.

In that ruling, U.S. District Court Judge Sharon Gleason said Trump violated the law with a 2017 executive order that reversed President Obama’s actions withdrawing most U.S. Arctic waters and portions of the Atlantic Ocean from the federal offshore oil and gas leasing program. Presidents have the right under the Outer Continental Shelf Lands Act to withdraw areas from leasing, but adding areas to the leasing program requires Congressional action, Gleason said in her ruling.

The ruling erected a new hurdle to a planned 2019 Beaufort Sea lease sale and threw the Trump administration’s entire five-year leasing plan into question
