Wilkins-Ellsworth
Trans Arctic Submarine Expedition

The following images and information is from the Sunday March 1, 1931 edition of the
Syracuse American News Paper. I have not been able to find out of this paper still is
in publication. I can find no reference to it on the web or in phone books. It may have
been absorbed by another paper or just gone out of business as many papers have.

The Wilkins-Ellsworth Trans Arctic Submarine Expedition obtained the former USS O-12 from the United States Navy and renamed her Nautilus. With the help of submarine inventer and designer Simon Lake, modified the boat for its proposed under ice mission. The under-taking was a failure ultimately and the submarine was scuttled in 1100 feet of water near Bergan Norway. She was rediscovered by a Norwegian dive team in 1985 and a planned recovery has been discussed over the years.

Equipped to dare an unknown sea-
The remarkable cross-sectional view of the Nautilus prepared from engineer's diagrams provided by Simon Lake, noted submarine builder and designer of many of the unique devices carried by the vessel to safeguard her beneath the Arctic pack.
This shows the submarine as she would appear raised against the pack with the runners of her 'sled deck' imbedded in its under side to to hold her stationary while she uses her ice drills to reach the surface and get air or put men on the flows' surface for scientific research.

Nautilus in cross section.
Sectional close-ups starting with the bow  will follow. The article had items numbered so
I will use their systems in pointing out the different features of the submarine. The original
deck line of the former USS O-12 can be seen sweeping from the bow towards the stern
about 1/3 of the way down from the top of the vessel.
