A real-time spetrogram instrument has been developed to provide an inexpensive and field-portable instrument for the analysis of animal sounds. The instrument integrates a computer graphics display package with a PC-AT computer equipped with an A/D board and a digital signal processing board. It provides a real-time spectrogram display of frequencies up to 50kHz in a variety of modes: a running display, a signal halted on screen, successive expanded views of the signal. The signal amplitude may also be displayed. Portions of the scrolled data may be saved to disk file for future viewing, or as part of a database collection. The screen display may be manipulated to adapt to special needs. Program source listings are included in the text.

Characterization of methane hydrate host sediments using synchrotron-computed microtomography (CMT) Jones, Keith W.; Feng, Huan; Tomov, Stanmire; Winters, William J.; Prodanovic, Masa; Mahajan, Devinder (Elsevier B.V., 2006-10-16)The hydrate–sediment interaction is an important aspect of gas hydrate studies that needs further examination. We describe here the applicability of the computed microtomography (CMT) technique that utilizes an intense ...
The use of diagnostic imaging for identifying abnormal gas accumulations in cetaceans and pinnipeds Dennison, Sophie; Fahlman, Andreas; Moore, Michael J. (Frontiers Media, 2012-06-06)Recent dogma suggested that marine mammals are not at risk of decompression sickness due to a number of evolutionary adaptations. Several proposed adaptations exist. Lung compression and alveolar collapse that terminate ...
