Progress on detection of radioactivity by airborne equipment
Frank W. Stead
1949, Trace Elements Investigations 83
Coincidence and anti-coincidence counting rate meters and also an air conductivity meter have been installed in a transport plane to measure gamma radiation from ground sources. Materials containing 0.01 percent uranium can be detected at 500 feet and at an airspeed of 150 miles per hour....

William A. Fischer
1949, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 10
At the interim meting of the Technical Committee in Fairbanks, Alaska, in September 1949, the Navy Oil Unit was requested to make photo-geologic analysis of the Driftwood, Awuna, and Carbon Creek anticlines before the November meeting. A report on the photogeology of the Driftwood anticline, based on available air photos,...

Preliminary results of prospecting of the "leached" zone over phosphate deposits in NW 1/4 of sec. 9, T. 31 S., R. 25 E., Polk County, Florida
Robert H. Stewart
1949, Trace Elements Investigations 100
The NW 1/4 Sec. 9 T. 31 S., R. 25 E. is underlain by a 4-to-15-foot thick layer of leached zone material in which the uranium content ranges from 0.001-0.018 percent. Several well defined areas of relatively high uranium content are outlined on figure 2. The International Minerals & Chemical...

Fourth special report of the Hawaiian Volcano Observatory of the U.S. Geological Survey and the Hawaiian Volcano Research Association: Steam blast volcanic eruptions: A study of Mount Pelée in Martinique as type volcano
T. A. Jaggar
1949, Report
The investigation is concerned with the author's expedition to Martinique and St. Vincent in 1902 and comparison of the experience of investigators and sufferers with that of others in so-called "explosive" eruptions. The Hawaiian mechanism is reviewed with special reference to rifts, underground water, intrusion furnace, wedge rupture, and lowering...

Trends in the lake trout fishery of Lake Huron through 1946
Ralph Hile
1949, Transactions of the American Fisheries Society (76) 121-147
The production of lake trout, Cristivomer namaycush (Walbaum), in the United States waters of Lake Huron was highest in the earliest years for which there are statistical records, averaging 2,362,000 pounds in 1879–1894. The general level of yield was much lower but relatively stable in 1895–1939, during which period the...

Le stéréorestituteur Kelsh est un appareil de restitution à double projection basé sur le principe des anaglyphes, comme le Multiplex par exemple, mais il a une plus grande précision que ce dernier, vu que les négatifs sont utilisés directement pour la restitution, sans que l'on soit obligé de les réduire...
