Katmai Bear Cam 2019

The Bear Cam is back up & running at Brooks Falls in Katmai National Park. The National Park Service has teamed up once again with explore.org to offer bear viewing in your living room.

The sockeyes started to come in last week, and the brown bears arrived right after that. There were 15-20 bears in sight when I last looked at the cam.

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.

Big Ice on the Block

“War Path”


“Hades’ Hound” – technically not a ‘big block’, but I’ve always had a soft spot for hellhounds

I have not been out to Ice Alaska of late, but with the warm temps, I’m sure most of the carvings are now stumps of ice sitting in puddles. In fact, the past two days have seen temps stay above freezing. That is the first time since recording began, that Fairbanks has seen consecutive days in March stay above 32F degrees.


Museum of the North

Located on the West Ridge of the University of Alaska campus in Fairbanks, is the Museum of the North. The museum takes on the daunting task of introducing visitors to the vastness and diversity, that is Alaska.


Otto the Brown Bear

“Otto” has been greeting visitors to the museum since its inception. He stands, all 8’9″ of him, at the opening of the Gallery of Alaska. The gallery is divided into the five main geographic regions of the state: Southeast, Southcentral, Interior, Western Arctic Coast and Southwest. Originally from Herendeen Bay on the Alaska Peninsula, Otto weighed 1250 pounds at the time of his death.

Locked in the permafrost, mammoth skulls have often been found by miners, as they worked the frozen ground for gold. Thirty-one, known, species of Pleistocene mammals roamed Alaska’s ancient grasslands with the mammoth.

“Blue Babe”

Blue Babe is probably my favorite exhibit at the museum. An extinct, mummified, steppe bison, that was discovered in the permafrost by placer miners in 1979. The bison died around 36,000 years ago, killed by an American Lion. The claw and tooth marks can still be seen on the carcass. Shortly after the kill, just before winter, the bison was covered by silt. It was then entombed in cold earth and frozen until excavated.

There are only two other discoveries from the permafrost, that have been reconstructed and put on display like Blue Babe. One a juvenile mammoth and the other an adult mammoth, both are at the Zoological Museum in Leningrad.


Even today, Blue Babe has an American Lion looking over its shoulder

The American Lion, now extinct, was around 25% larger than the modern lion. They roamed North America in the Pleistocene epoch, 340,000 – 11,000 years ago.

The museum is open every day in the summer, and slightly shorter hours M-Sat in the winter. Admission is $14 for adults.

International Polar Bear Day 2019

Wednesday, 27 February, is International Polar Bear Day.

There are 25,000 estimated polar bears world-wide. On average, a male polar bear weighs 1500 lbs, and can stand close to 10 feet tall on its hind legs. The largest known came from Alaska, and stood 12 feet, and weighed 2210 lbs. Females are quite a bit smaller, weighing on average 500 lbs, and only standing 8 feet tall.

Polar bears are closely related to brown bears. The two populations likely became isolated around the time of the last ice age, around 150,000 years ago. The two species can interbreed, but have adapted to very different habitats. Neither species would last long in the other’s habitat. For example, the polar bear is so adapted to the Arctic climate, that they can not take temperatures above 50F for very long.

Only female polar bears who are pregnant hibernate. Male bears are active year round.

Polar bears can, but rarely, live past 25 years in the wild. Although, in captivity, they have reached 43 years.

Russia outlawed the hunting of polar bears in 1956, the United States began protecting them in 1972. Regulation in Greenland started in 1994. Currently, Canada allows the hunting of up to 500 polar bears annually.
