Like other parts of the

Like other parts of the Earth's crust, Svalbard has moved around the globe due to continental drift. At times it was further south, and also the climate of the past at certain times was much warmer. So there is evidence of a tropical climate during Jurassic times (200-145 million years ago)....{read more}

Remember that we only stopped

Remember that we only stopped over in the city of Longyearbyen before flying up to the research base where we spent most of our time. Svalbard is a huge area, and Longyearbyen is the "big town". I don't know why they painted in all the different colors - probably to brighten up a rather drab...{read more}

Nope. It's a very rare thing to encounter a polar bear and even more rare for the polar bear to attack. So no one I was with ever had to actually shoot a bear.

I'm not sure - this is just what we were told. Signs of polar bear aggression are mainly if the bear is moving towards you and not making any signs of turning away. Also if you see a polar bear that seems to be stalking you over time.

We're used to ice being

We're used to ice being transparent-looking because most of the colors in the spectrum travel right through it (to a point - if the ice is thick enough the light will eventually be absorbed, and it will appear dark). Or we are also familiar with snow being white - this is because each tiny...{read more}

We have seen many types of birds - Kittiwakes, Arctic Terns, Skuas, Snow Geese to name a few. Also we saw Arctic Foxes, Bearded Seals and Svalbard Reindeer. I did see polar bear footprints but no actual bears.

Lakes can form when meltwater

Lakes can form when meltwater accumulates on a glacier for a long period of time. This would happen particularly when the glacier becomes stagnant - when its flow rate goes way down. Microbial life can exist in these lakes, and they would then leave organic deposits at the bottom. We saw an...{read more}

That's a great question, Hal!

That's a great question, Hal! The mud can be used to tell us quite a bit about how fast the glacier is receding, and what types of "plumbing features" might exist under and around the glacier. For example, I've discussed two interesting features - the "upwelling plume" and the "delta". These are...{read more}

Ha ha! I have no idea. You'd have to ask a farmer. It must be pretty good, though, as there is tons of plant life under the bird colony where the ground is mainly barren most other places on the island.
