Geez. That sounds horrific.
Twas fecking dramatic. The trouble is there's nothing to stop the trailer slidding. If you use the back brake too much you jack knife. My driveway is 20m long with over 10 % of incline. So once the trailer picked up momentum, pushing myself sideways into the fence was my only hope of stopping it.
I usually walk the trailer down, and let the kids jump in from there. My eldest will no doubt tell of his adventure to Mrs Smallfurry. Then the real suffering will start.

With a cargo trike, you would have brakes on the wheels either side of the load. Also you can let the bike skid as you find the traction limit.
When I am riding down icy hills I cant risk the front washing out, as it usually means a fall. But with heavily loaded trailer behind. I cant let the rear slid out too much either.
I was toying with the idea of adding some old kids skis to the trailer. In a detachable manner. So I can take the kids or large loads. Snow biking. Kinda gone off the idea now.

I was thinking about floatation mostly. Also I have loads of kids skis lying around. Kids skis often have bindings which strap to a standard winter shoe. This to eliminate the need to constantly buy new ski shoes as the little ones grow. So I might be able to swap the straps for transport straps, and attach them to the wheels. This would allow them to move with the terrain.

The heavy kids'l keep it going straight.

Maybe Arctic sea ice is either smooth or completely unridable.
I think you'll find it's for the antarctic so it should be fine. The antarctic plateau is relatively smooth, but very cold, -70 wind chill, lovely. The main trouble will be getting up there, it's pretty steep and mountainous around the edge, or creaking crevass filled glacier, but I gues she has a decent route
I severely doubt anyone would attempt to cycle across the arctic, unless they have a pontoon. Even in the coldest winter, 5-50m wide leads will open up every 50-100km. In the summer, forget it, a very silly idea, may as well use a pedalo, an ice breaking breaking, triple hulled pedalo perhaps, it would be quicker.

Do they teach nothing in schools these days!!?

The Antarctic is almost a geographic opposite of the Arctic, because Antarctica is a land mass surrounded by an ocean. The open ocean allows the forming sea ice to move more freely, resulting in higher drift speeds. However, Antarctic sea ice forms ridges much less often than sea ice in the Arctic. Also, because there is no land boundary to the north, the sea ice is free to float northward into warmer waters where it eventually melts. As a result, almost all of the sea ice that forms during the Antarctic winter melts during the summer. During the winter, up to 18 million square kilometers (6.9 million square miles) of ocean is covered by sea ice, but by the end of summer, only about 3 million square kilometers (1.1 million square miles) of sea ice remain.

She started at 83 South, inland and is on snow, we can be pretty confident it isn't salty.
The snow here is unlike anything I have seen. There is no precipitation and it is so cold there's no moisture in the snow. It's like sand: gorgeous to look at, grainy to the touch and a nightmare to cycle in as it parts like waves under our tyres.
Fair play to her!

would the small wheels not be harder to get over that terrain than larger ones?
It'll be to do with gearing, won't it? The only way to get a gear low enough out of a standard cassette/chainring setup is to reduce the wheel size, and as you reduce the wheel size you need to increase the width to maintain traction. Then they need to increase width further to increase traction to take account of the force required to try and drag an 82kg trailer.
An IHG could provide a better ratio but 1.if it breaks, they are fucked. 2.The grease inside would freeze/like treacle at those temps.
They are only going at less than normal walking pace anyway so if they come across an obstacle it's just as easy to get off and lift the bike over it.
-
The angle of attack of smaller wheels is greater. They also get bogged down in smaller holes. At the width of the hannerbrink tyres. I'm guessing weight is a diameter limiting factor.

"Icelandic Arctic truck drivers who provide logistical support"
Pfft. Cheat.
Like you dont do the same, on your epic rides.
