Well, snow crystals by themselves may not tell us that much about changes in climate, but their composition might (how much oxygen versus nitrogen, for example). This is how we tell past climate -- by looking at ice cores

How can studying snow crystals tell us about climate change?

There are 28 Polar Huskies. Some of the retired dogs live in homes now with other people but they are still part of our Polar Husky Super Star Pack.  :)

You may learn about all of the Polar Huskies in the Kennel.

How many dogs do you have in all?

While in Kangerlussuak, Andrea, Brant and Tim saw Russells Glacier.

Did you see the photos, the movie, or the 360 of Russells Glacier in the Scrapbook this week?

Have you seen any glaciers?

Some glaciers retreat because their plumbing changes -- the melt water they glide on either flow more rapidly or slowly for reasons not related to climate. However, we (humans) don't want to be the cause of retreating glaciers because of the greenhouse gases we emit -- that wouldn't be so good.

Is the iceberg retreating a bad thing?

We study snow by going place where there's lots of snow. We dig in the snow and collect crystals to examine back in the lab. We also use satellite and aircraft fitted with special instruments to look at snow. In addition, we look at past records of snowfall.


How do you study snow? We want to know everything about how you study snow.

It is basically a full-time job to prepare the electronics to go in the field and to keep them working while we are out there. The most important thing is to ensure that the electronics do not collect moisture on the inside parts. To avoid this, it is very important that we warm all the equipment up to inside temperature (inside the tent's temperature) before we try to turn it on. And we keep everything in Ziploc bags and as airtight as possible for the same reason.

So, when we need to use the computers on Education Day, the morning starts around 5 am to get the heat going in the tent. Then, we take the computers and lay with them in the sleeping bags, for example. It easily takes 3-4 hours to get everything—cords, computers, cameras, etc. warmed up from the time we wake up. Then we need to power everything—including the batteries for the cameras that we use during the week.

We have three ways to power our technology. We use solar power whenever possible. Then we have a small Honda generator. Last, we have what is called "expedition grab it batteries." These work for a number of hours down to -40 degrees F (-40 C), but cannot be recharged. They are good if we run completely out of other power sources.

How do you charge your batteries in your computers when you are out in the wild with no outlets?

Great observation Tabitha!

For a $20 donation, we will send you a poster. It's a great way to support the GoNorth! program and the Polar Huskies.

You may learn more and see all the posters that are available in Get Your Poster!

We noticed that some of the classrooms that Tracker visits have GoNorth! posters in there. Do only schools that get Tracker get posters?

All of them! Each of the positions are equally important! Watch the great movie Teamwork to learn what makes a Polar Husky Team!


 

What is the most important position in the dog sled?

Most of the dogs will eat 5000 to 6000 calories a day- the same amount of calories that us two-legged team members will eat too.

Did you see the picture in the Photo Journal this week of Baffin getting fed? As one of the largest (possibly the largest) dogs in the kennel, he got 15 cups of food which is 3.5 kg or 7.5 lbs!

How many kilograms does the polar husky eat each day?

No people actually live at the North Pole. The North Pole is a geographical spot in the Arctic Ocean.

BUT, we have learned a lot of our survival skills from the natives of the Arctic. If not most of them, because our skills were passed down to us from earlier explorers, who read or learned from other earlier explorers who learned "how to" from the natives.

And we are still learning today.

Have you ever learned any survival skills in your life from any natives of the north pole?
