Direction-of-Arrival Estimation Methods in Interferometric Echo Sounding [PDF]
Sensors, 2020 Nowadays, there are two leading sea sounding technologies: the multibeam echo sounder and the multiphase echo sounder (also known as phase-difference side scan sonar or bathymetric side scan sonar). Both solutions have their advantages and disadvantages,

Towards Underwater Macroplastic Monitoring Using Echo Sounding
Frontiers in Earth Science, 2021 Plastics originating from land are mainly transported to the oceans by rivers. The total plastic transport from land to seas remains uncertain because of difficulties in measuring and the lack of standard observation techniques.

BedMachine v3: Complete Bed Topography and Ocean Bathymetry Mapping of Greenland From Multibeam Echo Sounding Combined With Mass Conservation. [PDF]
Geophys Res Lett, 2017 Greenland's bed topography is a primary control on ice flow, grounding line migration, calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates the penetration of warm Atlantic water (AW) that rapidly melts and undercuts Greenland ...

Echo Sounding in Fishery Research [PDF]
Nature, 1935 THE vessel used for the annual oceanographical investigations in the Lofoten area (the Johan Hjort) had a Hughes echo sounding gear (magnetostriction system, frequency 16,000 cycles per second) installed before leaving Bergen last February. The gear worked smoothly all along the coast and besides furnishing a great number of interesting sections ...

Acoustic Antennas for Atmospheric Echo Sounding [PDF]
The Journal of the Acoustical Society of America, 1972 The successful utilization of acoustic waves for atmospheric echo sounding requires an efficient antenna, with high on-axis gain and suppressed sidelobes. Existing microwave antennas and optical searchlights have been adapted for acoustic use, and their performance measured.
