Why deposits of longitudinal dunes are rarely recognized in the geologic record Why deposits of longitudinal dunes are rarely recognized in the geologic record
Dunes that are morphologically of linear type, many of which are probably of longitudinal type in a morphodynamic sense, are common in modern deserts, but their deposits are rarely identified in aeolian sandstones. One reason for non-recognition of such dunes is that they can migrate laterally when they are not exactly parallel to the long-term sand-transport direction, thereby...

Sea-floor-mounted rotating side-scan sonar for making time-lapse sonographs Sea-floor-mounted rotating side-scan sonar for making time-lapse sonographs
A rotating side-scan sonar system was designed to make time-lapse sonographs of a circular area of the sea floor. To construct the system, the transducers of a commercial side-scan system (frequency 105 kHz; pulse length 0.1 ms; horizontal beam width 1°; vertical beam width 20°; beam depressed 10° with respect to horizontal) were mounted 2 m above the sea floor on a vertical shaft that...
