Here’s pretty much everything about them (wiki)

The American Miscellaneous Society (AMSOC - 1952 to 1964) was formed by Gordon Lill, of the Office of Naval Research, as an organization designed to collect various Earth science research ideas that were submitted by scientists to the U.S. Navy and didn’t fit into any particular category.

Membership in AMSOC was open to everyone and so there was no official membership list.

Prospective members could join whenever two or more members were together.

The most famous project to come out of AMSOC was the Project Mohole, whose goal was to drill into the Earth’s mantle. The society dissolved itself in 1964.
