Pineapple Express

There was a time when I really enjoyed hearing terms like “Pineapple Express” and looked forward to a warm “Chinook” wind blowing through the area.

Now they comes with such frequency, that the deep freeze has replaced them as the rare events in the state.

A Pineapple Express came through Alaska over the weekend. Fairbanks saw rain and temps in the 40’sF. Our dusting of snow took a beating. The ice on The Pond has reverted back to slush.

Bethel on the western coast saw 53F on Sunday morning. The second highest temperature recorded this late in the year.

King Salmon reached 60F on Sunday, breaking their record for the warmest temperature this late in the year.

Not to be left out, McGrath in the Interior hit 50F, which tied their record set 7 years ago.

Utqiagvik on the Arctic Coast will see 38F on Monday, which will do absolutely nothing to help our utter lack of sea ice.

The times, they are a changing…


Arctic Research aboard the RV Polarstern

Researchers from around the globe have congregated on Alaska’s Arctic coast. They are planning a once in a generation expedition into the heart of one of the harshest environments on Earth: The Arctic.

It’s a 12 month, 17 nation, 300 scientist effort aboard the German ice breaker Polarstern, to document climate change in the Arctic. This coming autumn, the Polarstern will be positioned in a remote part of the Siberian Arctic, and then wait to be frozen in the ice. The research vessel will then flow with the floe; traveling with the ice as it moves across the Arctic Ocean.

Only twice has a transpolar drift happened successfully in history. Norwegian explorer Fridtjof Nansen did it first in 1893. Ten years ago, a small sailing ship named the Tara also completed a transpolar drift without the sea ice crushing its hull.

NASA’s Goddard Space Flight Center, the National Science Foundation and universities from Alaska-Fairbanks to Oregon State to Dartmouth are involved. Most northern nations are playing a role, as well. Russia, China and Sweden have all committed ships and aircraft for resupply support. Japan and Switzerland have developed new research equipment especially for the expedition.

Unlike Antarctica, there is no land at the north pole to build a permanent research station. The RV Polarstern is the next best thing. At any one time, 60 people will be living and working on the ice breaker. Resupply will take place every 60 days, weather permitting. Researchers will also be swapped out during resupply runs.

Time is running short for a expedition like this one. The key is to find old sea ice, 4-5 years old, and get locked into that. Since 1980, 95% of Arctic sea ice that is 4+ years old, has been lost. In the graph above, the lightest yellow is 1 year old ice, the dark purple 5+ years old.

It should be an interesting study, although researchers on board the ice breaker from December to February will not see the sun. They should see polar bears, however.
