Merged ground penetrating radar display for multiple antennas

Abstract: In an embodiment of the disclosed technology, a visual output of data from a ground-penetrating radar is displayed on a visual medium. The display has a first exhibition of output from a higher frequency range antenna, a second exhibition of output from a lower frequency range antenna (compared to the other antenna; see definition in the "detailed description"), and a transition area between the first and second exhibition having merged data from the lower frequency antenna and the higher frequency antenna. The depth range of the transition area may be varied based on optimal depth range of each antenna, such as manually by a viewer viewing the visual output, which may occur in real-time, that is, while operating the radar and viewing the visual output thereof. Or, the transition depth range and/or width of the transition region may be varied as part of post-processing.

Magnetic measurements in the south-west Pacific Ocean

Abstract: Total magnetic force and bathymetric profiles totalling 25,000 km have been measured in the South-West Pacific Ocean between New Zealand, Fiji, and the Cook Islands. The magnetic anomalies exhibit characteristic patterns which may be correlated with different physiographic regions. Anomalies of amplitude less than 200 γ prevail over the Norfolk Basin, the flanks of the Tonga-Kermadec Ridge, and the South-West Pacific Basin north of 18° S, including the Manihiki Plateau. Amplitudes from 200 to 500 γ occur over the South Fiji Basin, Three Kings Rise, Colville Ridge, Havre Trough, and the South-West Pacific Basin south of 18° S; and with a marked short wavelength (<10 km) component over the North Fiji Basin, Hunter Ridge, and Lau Basin. The largest anomalies, with amplitudes between 500 and 1,000 γ, are found over the Kermadec Ridge. From a comparison of adjacent profiles there is an indication of a north-easterly trend in the magnetic anomalies over the Lan Basin between Fiji and Samoa. Model studi...
