Practical Differences Between Photogrammetric Bathymetry and Physics-Based Bathymetry
IEEE Geoscience and Remote Sensing Letters, 2022Optical satellite remote sensing (RS) is a time- and cost-effective approach for shallow-water bathymetry over large areas. The photogrammetric and physics-based methods, which do not require in situ depth calibration data, are two implementations of RS-based bathymetry.

The design and performance of a short-pulse high-repetition-rate CuBr laser suitable for bathymetry is described. The pulse width and peak power were 4.5 nsec and 30 kW, respectively, corresponding to 140 microJ/pulse. These conditions occurred at a repetition rate of 16 kHz and an overall efficiency of 0.14% within a compact long-lived sealed-off ...

Abstract Through an extensive literature review the results of previous lidar investigations in Australia, Canada, Sweden, the U.S.A. and West Germany have been evaluated. Based on these findings estimates are given for the anticipated depth capability, measurement accuracy and operational constraints for a laser system in U.K. waters. Consideration is

We want to measure water depth and chlorophyll content on coastal areas from satellite. This should be done using a green laser, which partly is transmitted on the sea surface and partly reflected. We want thereby to detect two return signals by help from a avalanche photodiode.

Airborne electromagnetic bathymetry
GEOPHYSICS, 1984Airborne electromagnetic techniques provide an efficient means for determining the bathymetry of shallow seas and coastal regions. Offshore time‐domain data collected with the INPUT® system may be interpreted quickly and inexpensively using the simple table look‐up algorithm described here.

Airborne electromagnetic bathymetry
Geoexploration, 1991Abstract An experimental airborne electromagnetic (AEM) survey was carried out in the Cape Cod Bay area to investigate the potential of extracting bathymetric information over a shallow ocean. A commercially available Dighem III AEM System was used for the survey without any significant modification. The helicopter-borne system operated at 385 Hz and

Abstract The oceanic regions located north of the Arctic Circle are the Arctic Ocean, the Norwegian-Greenland Sea, and Baffin Bay (Plate 1). The latter is described in Keen and Williams (1990). Despite the bold isobaths in Plate 1, the bathymetry of the Arctic Ocean is still poorly known. Most of the Norwegian-Greenland Sea, on the other
