Alaska Has New Lakes. Unfortunately, They’re Releasing a lot of Methane


A NASA scientist is discovering newly fashioned lakes in Alaska which might be belching greenhouse gases at a excessive price. The principle one is methane, a fuel many individuals use of their pure gas-fueled grills. She’s monitoring these emissions in considered one of Earth’s most distant areas—the Arctic. It has hundreds of thousands of lakes, lots of them tons of or hundreds of years outdated. However, solely the youngest of them are releasing excessive quantities of methane. And that’s as a result of results of local weather change on these delicate environments.

Katey Walter Anthony is an ecologist on the College of Alaska-Fairbanks working with NASA to check this area. She factors out that the looks of youthful, methane-belching lakes is a harbinger of issues to return. “In order that’s a priority for the long run, after we take into consideration permafrost carbon suggestions, are areas which might be newly thawed,” she stated.

One among Walter Anthony’s jobs is to pattern the fuel content material on the lakes within the area utilizing methane assortment units that bob on the floor of the water. The bottles might be taken to the lab and the fuel analyzed. However, within the area there’s a fast technique to inform how a lot methane is within the lake: merely gentle a match on the finish of the bottle’s valve. A flame flares out within the presence of methane, nearly like lighting a camp range.

Local weather change and Permafrost Thaw = Extra Methane

Walter Anthony has been finding out Large Path Lake in Alaska. It’s an excellent instance of a methane-rich thermokarst lake that fashioned lower than 50 years in the past, she stated. Large Path is considered one of a number of on the focus of NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) venture which seems at how rapidly local weather change is affecting the Arctic areas. The “signs” of this variation are diminished Arctic sea ice, thawing of permafrost soils, decomposition of long-frozen natural matter, widespread adjustments to lakes, rivers, coastlines, and alterations of ecosystem construction and performance. The ABoVE venture has been conducting an airborne marketing campaign since 2017 as a part of NASA’s Terrestrial Ecology program. It research components of Alaska and Western Canada.

Younger lakes like Large Path Lake are harbingers of issues, says Walter Anthony as she tracks the formation of thermokarst usually. She is how the altering local weather will trigger extra of those lakes to type as extra permafrost melts. “Lakes like Large Path are new, they’re younger, and they’re essential as a result of these lakes are what’s going to occur sooner or later,” she defined.

Forming a Thermokarst Lake

Large Path was created as subsurface permafrost thawed. As that underground ice melted, the bottom it was frozen into collapsed and fashioned a watery sinkhole. The high-quality particulars are extra advanced. When a permafrost layer thaws beneath lakes, issues begin to occur. Typically, microbial exercise will increase, and pathways type within the permafrost. At Large Path Lake and others within the area, the microbes digest lifeless crops and different natural matter within the beforehand frozen soil in a course of that produces carbon dioxide and methane.

Typically, permafrost thaw can type lengthy empty tubes or ‘chimneys’ beneath lakes. These enable methane and different gases trapped deep underground to flee. This launch of ‘geologic’ methane into the environment can also be occurring at Esieh Lake, one other of Katey Walter Anthony’s ABoVE research websites.

“At Large Path Lake, it’s like opening your freezer door for the primary time and giving all of the meals in your freezer to microbes to decompose. As they decompose it, they’re belching out methane fuel,” she identified.

The Seasonal Freeze-Thaw Cycle Additionally Traps and Releases Methane

Because the lakes freeze within the winter, methane bubbles forestall ice from forming. That creates areas of open water that enable methane to flee all through the season. In different areas, the methane bubbles create frozen domes of ice on the floor of a lake. It’s a pure course of, however over the previous few many years, it has been accelerated by local weather change and hotter Arctic temperatures.

“As soon as the ice has fashioned on these lakes, the rising methane bubbles will freeze into the ice,” explains Franz Meyer, Chief Scientist on the Alaska Satellite tv for pc Facility in Fairbanks. Meyer can also be one of many chief scientists for NISAR, a joint NASA and ISRO satellite tv for pc that can research our planet—and the Arctic, particularly—utilizing airborne radar. It’s a difficult mission, a part of NASA’s bigger curiosity in monitoring methane from area, the air, and the bottom.

“These bubbles that we see within the ice change the way in which that the radar sign interacts with the ice floor,” he defined. Radar waves bouncing off the floor of a lake or the land can detect roughened areas. A few of that roughness comes from the methane bubbles just below the floor. A thermokarst lake with a excessive roughness probably has methane content material in its bubbles. And, the science workforce finds that they have a tendency to have larger methane emissions than clean lakes. Combining the airborne radar information with measurements collected within the area permits scientists to estimate how a lot methane lakes are emitting throughout a big area.

The formation of latest thermokarst lakes will proceed as world local weather change raises temperatures. The Arctic areas like those that Walter Anthony is finding out are nearly functioning like “canaries within the coal mine”. Their higher-than-normal emissions will proceed to pump greenhouse gases into the environment, enhancing future cycles of melting and methane launch.

Canada’s LNG industry set to take flight as interest reignites in Alaska megaproject

Canada’s LNG industry set to take flight as interest reignites in Alaska megaproject


CALGARY — Hundreds of kilometres up the Pacific coast from where Canada’s first liquefied natural gas export terminal is set to start up this summer, a monster lays dormant.

Alaska has long had ambitions to ship its natural gas to international markets, but the cost and scale of such an undertaking has held it back for decades.

But there’s been renewed interest in the megaproject since U.S. President Donald Trump issued an executive order on his first day in office devoted to Alaska resource development. State officials, including Gov. Mike Dunleavy, have been busy in recent weeks trying to woo potential Asian buyers of the gas under long-term contracts.

Industry experts have doubts the Alaska behemoth will awaken this time, but they say Canada must be mindful of the threat it could pose to its own nascent LNG industry.

“If there’s a time to build it, now would probably be your best bet,” Enverus senior analyst Josephine Mills said of the Trump administration’s keenness on Alaska gas and the Republicans’ control of Congress.

“But then again, this has been being talked about for the past 30, 40 years. It’s by no means a new project. So definitely I think it would be faced with a lot of hurdles to come.”

With an estimated price tag of US$44 billion, Alaska LNG would see a 1,300-kilometre pipeline traverse the state from north to south, passing through treacherous terrain to deliver an average of 3.5 million mmBTU a day of gas to a liquefaction plant in Nikiski, south of Anchorage. The project also includes a carbon capture plant by the gas fields on Alaska’s North Slope.

Some of the gas would be for Alaskans’ needs, but most would be loaded onto tankers and sold across the Pacific, the same markets Canadian LNG developers want to tap.

“It would be beneficial to Canada to not have Alaska LNG be built,” said Mills.

But if it did go ahead — and that’s a big if — it would be after 2030, she added.

Late last month, the state corporation behind the massive endeavour, Alaska Gasline Development Corp., signed Glenfarne Group as lead developer on the project. Glenfarne, a U.S. builder of energy infrastructure, now owns 75 per cent of the project, AGDC holding the rest.

A final investment decision on Alaska LNG is expected some time this year.

Kent Fellows, an economist with the University of Calgary’s School of Public Policy, said contracts to buy LNG are signed before plants start up and usually span several years.

So the trade chaos Trump has unleashed with a bevy of tariffs against one-time allies does the Alaska project no favours.

“It can be really costly to make some of these investments if you’re not sure that trade relationship is going to be stable going forward,” Fellows said.

“One of the huge advantages that the United States had up until about 12 months ago (is) they had a reputation for being a very stable economy, being an economy that believed in global free trade.”

If Alaska LNG is somehow successful in sewing up contracts with Asian buyers, it makes it harder for B.C. projects further behind in development to secure enough demand to justify their own plants.

“With an LNG market, that competition happens at the time the facility is built, so timing the market can end up really, really important,” said Fellows.

However, the CEO of Canada’s biggest natural gas producer said there should be plenty of interest to go around.

Mike Rose, who heads up Tourmaline Oil Corp., foresees worldwide demand soaring by up to 50 million mmBTU by 2035.

“We won’t be oversupplying because there might be a project that comes on in Alaska,” he said. “We need all of them.”

In a speech to Canadian Club Toronto last week, TC Energy chief executive François Poirier said he’d like to see a “Team Canada” approach to developing LNG.

TC Energy built the pipeline that ships gas across B.C. to the LNG Canada terminal in Kitimat.

“In Alaska, the U.S. administration is today working toward signing (memorandums of understanding) for LNG with countries like Japan and South Korea,” Poirier said.

“The governor of Alaska has travelled himself to Asia to line up customers and investors for Alaskan LNG, and guess what? He returned from his trip with an agreement from Taiwan.”

Poirier said no matter which party wins the April 28 federal election, it will be key for the prime minister, premiers, businesses and Indigenous leaders to show a degree of alignment similar to the U.S..

“Collectively, we’ll have to travel to Asia and market ourselves and underscore that Canada is back in business and is a good risk to take.”

Federal employment and budget turmoil affects monitoring of Alaska’s Barry Arm landslide

The Trump administration’s mass firings of federal workers and funding restrictions has affected the monitoring of a landslide-prone slope that could create a dangerous tsunami in Alaska’s Prince William Sound.

The Alaska Division of Geological and Geophysical Surveys, in a recent update, alerted the public about the problems affecting the multiagency team monitoring Barry Arm. The site is a fjord where an unstable rocky slope could collapse into the water, potentially creating a tsunami affecting the community of Whittier and a variety of Prince William Sound mariners and visitors.

Administrative changes affecting federal agencies that are part of the Barry Arm monitoring program “have resulted in delays in equipment repairs and service renewals essential to maintaining full operational readiness,” the Division of Geological and Geophysical Surveys update said.

Those delays “may have temporary impacts on tsunami hazard awareness and response efforts in the region,” the update said.

The slope at Barry Arm has been moving gradually, and its movements are recorded through an array of instruments at the site and elsewhere in the sound.

Barry Arm is one of dozens of sites in Prince William Sound where landslide risks have increased as glaciers that buttress mountain slopes retreat. The sound and surrounding parts of Southcentral Alaska are considered vulnerable because of rapid glacial loss.

Because of Barry Arm’s potential for a catastrophic collapse, the site has received special focus from agencies trying to track slope movement. A key goal is to provide early warnings to people in the area, if those become necessary.

Federal agencies involved in the Barry Arm program include the U.S. Geological Survey; the National Weather Service and its National Tsunami Warning Center; the U.S. Coast Guard; and the U.S. Forest Service. Nonfederal partners include the Division of Geological and Geophysical Surveys and the University of Alaska Fairbanks’ Alaska Earthquake Center, and the cities of Whittier and Valdez.

Dennis Staley, of the USGS and Alaska Volcano Observatory, said that changes to federal agency priorities and protocols for travel, purchasing and contracting have affected the Barry Arm Landslide and Tsunami Hazard Monitoring System.

“These have resulted in some rather sizeable changes in the way we approach the logistics to conducting fieldwork in recent months. We also have to plan for and adapt to changes in workforce composition as our staff members are laid off, or offered, contemplate, and sometimes accept offers for early retirement, paid administrative leave, etc.,” he said by email.

Weather conditions have also affected operations, team members said.

USGS scientists went to Barry Arm on April 2 and did maintenance work on radar equipment used to measure landslide movement and transmit that data, Staley said.

National Weather Service crews also got out to the area earlier this month and restored service at a Whittier site that was recording water-level data, said Dave Snider of the service’s Tsunami Warning Center. Crew members were able to restore service there, but more trips will be needed “as time, weather, and funds allow,” he said by email.

No more field work is planned for this month, Staley said. Annual spring maintenance is planned for May, he said.
