Arctic Coastal Change
« on: August 10, 2017, 02:49:56 PM »
Hey everyone. I'm currently in the Arctic at the moment, specifically in Inuvik, NW, Canada. This afternoon I'll be leaving for Tuktoyaktuk and will spend the following 2 weeks studying coastal erosion processes at numerous sites all along the Tuktoyaktuk peninsula and out along the Mackenzie delta.

Unfortunately, a combination of haze and forest fire smoke made getting good photos from the flight in next to impossible. The air toward Yellowknife was better though.



I'll be in Tuk with a big team of other researchers, mostly Canadian, but others from all over too. Even the people you meet around are fascinating. For example, the two others sharing the house last night with myself and my supervisor - one is a cultural anthropologist that plans on living with some of the small local communities here and the other is studying methane release from lakes. Never a shortage of really cool people with fascinating projects going on, which I'll definitely discuss more over the coming weeks.

Anyway, busy day ahead loading and prepping for flights and boat trips, so I gotta go now. But I'll keep the updates coming - internet connection dependent of course.

Interesting news BFTV! I take it you guys are aware that some big waves are on the way to your vicinity?

Please let me know if you notice any Arctic coastal change as a result, though it looks like Utqiaġvik and thereabouts will have (had) the worst of it!

BFTV, that sounds amazing. Thank you for doing this. I wish you the best.

BFTV
What a marvelous adventure. Please fill us in whenever the gods of the internet allow.
I'm thrilled at having another contributing from the very jaws of the beast!

BFTV, if you feel like using the ASIB to share some of your experiences or write about coastal changes, you know where to find me. Good luck, have fun and learn as much as you can.

Have fun up there BFTV!

As regards the wildfires, Canada is not alone. I don't know how much access you have to the news channels, but even Greenland has been burning recently. (Brownland doesn't have quite that same ring to it, does it?)

Cheers guys. I'll try keep the updates ticking along.
Neven, I will try put together a proper update for the blog, life out in Tuktoyaktuk as a researcher, maybe some profiles on the other researchers we're with and the work we are all doing. Here's a quick pic of the thermokarst  lakes out by Tuk on the flight over today.

From Wikipedia:
Thermokarst is a land surface characterised by very irregular surfaces of marshy hollows and small hummocks formed as ice-rich permafrost thaws, that occurs in Arctic areas, and on a smaller scale in mountainous areas such as the Himalayas and the Swiss Alps. These pitted surfaces resemble those formed by solution in some karst areas of limestone, which is how they came to have karst attached to their name without the presence of any limestone. Small domes that form on the surface due to frost heaving with the onset of winter are only temporary features. They then collapse with the arrival of next summer's thaw and leave a small surface depression. Some ice lenses grow and form larger surface hummocks, which last many years and sometimes become covered with grasses and sedges, until they begin to thaw. These domed surfaces eventually collapse either annually or after longer periods and form depressions which contribute to uneven surfaces. These are included within the general label of thermokarst.

This was a new term for me.
Arctic ice is healthy for children and other living things.
