036_Ice_Diving

I’m sick of 2016.  A friend just died for stupid reasons and my extended family and many friends are facing life in the USA under president Donald Trump and his cabinet of elite racists.
I really have not been in the mood to read about noble suffering under the Victorian model of manliness and my notes about Scott’s death on his return from the pole came to a grinding halt about two weeks ago.
Here’s a Frankenstein’s episode stop gap comprising essays from the past about ice diving and contrasting Scott Base and McMurdo Station.
I’ll get back to the history in time for Christmas but in the mean time 2016 can fuck right off.

Here’s the link to the Absolute Antarctica article I mentioned and here’s one to the Ice Coffee Blog in case you have trouble finding it.

Fuck!

A dark clockwork comprising duty, ambition and hurt pride winds up Captain Scott and sets him on his path back to Antarctica.

Episode 035



Reginald Skelton tests the second snow tractor design before handing the plans on to the Wolseley Motor Company, which produced the three examples sent south.

From “Scientific American,” May 14, 1910, p. 396 cont. 407
The practical success achieved with the gasoline propelled motor sleighs on the Shackleton and Charcot polar expeditions has prompted Capt. Scott to include a vehicle of this type for his forthcoming dash to the south pole. This vehicle is, however, distinctly different from the motor sleighs hitherto used. In the two previous cases the front of the car was mounted on runners or skates, a chain and sprocket with spuds which gripped the snow and ice being fitted at the position occupied by the wheels in the ordinary motor car. In the new sleigh, however, what may be termed an adaptation of the pedrail or caterpillar system has been resorted to, which imparts a greater degree of efficiency to the vehicle, and enables it to surmount obstacles and to travel over rough ice with ease. In view of the conditions prevailing and the work it is intended to fulfill in the south polar regions, the engine is of a special type. It comprises four vertical cylinders, cast in pairs, and developing twelve brake horse-power.

The sleigh is fitted with a runner, upon which bear the rollers of the chain. The latter passing between this runner and the ground supports the whole vehicle and propels it as the wheels revolve. There are no brakes provided, as the big reduction ratio of the worm renders it completely irreversible, so that brakes are not necessary. Similarly, steering gear is dispensed with, as such is not requisite, for in any open area such as an ice field steering is not demanded. When it is required to deviate to the right or left, ropes attached to the front of the frame can perform this function. Turning sharp corners, under some circumstances is admittedly exceeding difficult, but when working in its designed sphere this difficulty will not be serious, as sharp turning can be usually avoided.
The sleigh has a substantial wooden frame. Underneath is fitted a large undershield extending end to end so as to present a perfectly smooth surface to the snow. When the sleigh is under way, a curious fact is observable. The chain, where it touches the ground, appears to stand still, while the sleigh slides over it. This is the motion that actually takes place, for the top of the chain travels forward at twice the speed of the sleigh. It will thus be seen that in reality the lower part of the chain in contact with the ground constitutes a surface over which the vehicle itself can move.

The driver has his position on a box behind the engine, which seat forms a receptacle for tools, spare parts and other accessories. That the vehicle has great climbing power has been conclusively proved, for it will ascend steep banks of earth and ride over serious obstacles easily and without any appreciable diminution of speed.
Although this sleigh can carry a party and full equipment, its actual function is to act as a tractor for the haulage of ordinary sledges, the trailing vehicles carrying the loads. Upon completion by the builders, the tractor was taken to Norway by Capt. Scott, and submitted to some exacting trials on snow-covered Lake Fefor and the tumbled country in its vicinity, where the conditions were somewhat analogous to those prevailing around the south pole. Heavily laden trailing sledges were hitched on to the tractor and numerous journeys were made among the Norwegian ice fields. The vehicle proved itself fully capable of withstanding rough usage, and Capt. Scott expressed his complete satisfaction with the results achieved.

Anthony Powell is the business

Anthony Powell has many, many Antarctic deployments under his belt and much, much videography expertise.  These two factors combined to produce the footage released in 2013 as “Antarctica: a year on ice.”  It stands as the single best movie about Antarctica I’ve ever seen.
I follow Anthony on teh facebooks and have enjoyed keeping up with his activities through the 2016 winter at Scott Base.  Recently he posted the appended footage recorded below the sea ice adjacent to Pram Point, the site of the New Zealand base.
The Weddell seal steals the visual show but there’s a lot going on otherwise.  The Bernacch in the foreground is my favourite but you can see some Odontaster seastars scattered around the site and what I suspect is a Glyptonotus isopod climbing a rock in the middle distance to the left of screen.
The recording features the amazing warbling noises Weddell seals make while underwater.  These sounds are made with the mouth closed, travel great distances and drive the owners of Moog synthesizers insane as they try and fail to make their oscillators recplicate that weirdness.
Anthony Powell knows what he’s doing and shares it with the world.  I use and recommend his output.

032 Pourqouis Pas? and the return of Sue.

Charcot leads his second Antarctic expedition aboard a new ship with a new engine.  What could possibly go wrong?
More groundings, more whimsy and more coastline explored.
Well done those Frenchmen.

Sue Halliwell provides Arctic contrast to her Antarctic experiences.

Episode 032

Justifiable French pride in Charcot’s expeditions expresses itself in stamps, literature and an injected styrene 1/100 scale kit with vac-form sails.  Heller yes!
