  pages={20 - 54}
ABSTRACT This article offers a new analysis of radionuclide and hydroacoustic data to support a low-yield nuclear weapon test as a plausible explanation for the still contentious 22 September 1979 Vela Incident, in which U.S. satellite Vela 6911 detected an optical signal characteristic of an atmospheric nuclear explosion over the Southern Indian or Atlantic Ocean. Based on documents not previously widely available, as well as recently declassified papers and letters, this article concludes… Expand
The Nuclear Fuel Cycle and the Proliferation “Danger Zone”
ABSTRACT Horizontal nuclear proliferation presents what is sometimes referred to as the “Nth country problem,” or identifying which state could be next to acquire nuclear weapons. Nuclear fuel cycleExpand

The 22 September 1979 Vela Incident: The Detected Double-Flash
ABSTRACT On 22 September 1979 two optical sensors on U.S. satellite Vela 6911 detected a double-flash of light that appeared characteristic of an atmospheric nuclear explosion conducted over theExpand
Evaluation of some geophysical events on 22 September 1979
TIROS-N plasma data and related geophysical data measured on 22 September 1979 were analyzed to determine whether the electron precipitation event detected by TIROS-N at 00:54:49 universal time couldExpand
Ultra long-range hydroacoustic observations of submarine volcanic activity at Monowai, Kermadec Arc
Monowai is an active submarine volcanic center in the Kermadec Arc, Southwest Pacific Ocean. During May 2011, it erupted over a period of 5 days, with explosive activity directly linked to theExpand
The underwater acoustic signature of a nuclear explosion at the ocean surface. Interim technical report
The gross spectral character and duration of the acoustic wave signature of a nuclear explosion near the ocean surface is estimated by constructing theoretical pressure-time histories, using modelsExpand
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) provides for monitoring of the whole globe by a network of stations, using various technologies, in order to verify absence of nuclear explosionExpand
The long-range detection of an accidental underwater explosion
During the Shallow Water 2006 Experiment, SW06, a power supply for seabed-moored oceanographic equipment suffered an accidental explosion. The equipment was located on the New Jersey Shelf, 175Expand
Hydroacoustic Propagation Through the Antarctic Convergence Zone: Study of Errors in Yield and Location Estimates for Explosive Charges
Abstract : A series of small calibration shots was conducted in late December 2006, along a transect from New Zealand to Antarctica in order to document the differences in spectral characteristics,Expand
The Hydroacoustic Component of an International Monitoring System
Abstract : The critical issue for the hydroacoustic component of an International Monitoring System (IMS) is its capability for monitoring nuclear explosions in the world's oceans. Factors thatExpand
Hydroacoustic signals generated by parked and drifting icebergs in the Southern Indian and Pacific Oceans
SUMMARY We report the detection, principally by the French Polynesian seismic network, of hydroacoustic signals generated inside large icebergs, either ‘parked’ along the Wilkes coast of AntarcticaExpand
Monochromatic T waves from underwater volcanoes in the pacific ocean: Ringing witnesses to geyser processes?
Abstract We analyze swarms of exceptionally intense and sustained T waves recorded during 1991 through 1994 at the Polynesian seismic array. The strongest swarm lasted 15 months and originatedExpand
