An overview is given of the July-August 1995 SWARM shallow-water internal wave acoustic
scattering experiment. This experiment studied both acoustic propagation through and …

Presented in a clear and concise way as an introductory text and practical handbook, the
book provides the basic physical phenomena governing underwater acoustical waves …

Objective: A chirp is a brief signal within which the frequency content changes rapidly.
Spectrographic chirps are found in signals produced from many biological and physical …

The seabed reflection amplitudes (SRAs) extracted from the sub-bottom profile have a
strong correlation with the types and physical properties of the seabed sediments. In this …

Chirp frequency-modulated (FM) systems offer deterministic, repeatable source-signatures
for high-resolution, normal incidence marine seismic reflection data acquisition. An optimal …

Features extracted from echosounder bottom returns are compared with the ground truth in a
North Sea survey area. The ground truth consists of 50 grab samples for which the grain size …

Abstract Although Ground Discrimination Systems and Multi-beam Echo Sounders tend to
be the preferred tools towards gaining knowledge about the seafloor, numerous surveys …

A warmer Arctic with less sea ice will likely improve macroalgae growth conditions, but
observational data to support this hypothesis are scarce. In this study, we combined …

The availability of lake bathymetry maps is imperative for estimating lake water volumes and
their variability, which is a sensitive indicator of climate. It is difficult, if not impossible, to …

A synthesis of high‐resolution (Chirp, 2–7 kHz) seismic profiles in the South Korea Plateau
reveals that large masses of wavy stratified sediment (≈ 60–90 m thick) cover broad, gently …
