Seafloor surveying with acoustic remote sensing has become a
powerful tool for researchers and professionals seeking knowledge
about the structure and behavior of the seafloor. In particular,
sidescan sonar is proving to be the preeminent technique, but its
data is often difficult to interpret due to the physics of acoustic
remote sensing, and to the varied geological processes at play.
This handbook not only presents all the fundamentals but also
explains how to interpret sidescan sonar imagery and bathymetry. It
fully explores the most recent advances, both in the technology and
in the knowledge of marine structures, and provides deep insights
for interpretation and decision-making. Broadly expanded and
updated from the previous 1997 Handbook of Seafloor Sonar Imagery,
this handbook is indispensable to oceanographers, resource
exploiters, telecommunications engineers, and marine researchers of
all kinds."
Buried waste on the seabed is a major source of pollution. But,
very often, waste sites are not known until a serious problem
occurs, or are not adequately mapped. Recent examples around Europe
include WWI and WWII ammunition dump sites (e.g. Beufort Dyke in
the UK), dumped nuclear submarines in the Arctic Seas, clandestine
or hidden toxic-waste in the Baltic Sea and the North Sea. Even if
properly documented, waste sites evolve with time (dumped material
can move with currents and tides, especially on a scale of decades;
toxic-material barrels can corrode and leak). This book shows the
results of a concerted EU-funded effort to tackle this problem and
find innovative ways to identify and map toxic waste sites on the
seabed, whether they have been covered with sediments or not. These
results are applicable to any region on the seabed in the entire
world.
This book, the first in a series of forthcoming volumes, consists
of topical and timely reviews of a number of carefully selected
topics in solar systemn science. Contributions, in form of
up-to-date reviews, are mainly aimed at professional astronomers
and planetary scientists wishing to inform themselves about
progress in fields closely related to their own field of expertise.
Offshore drilling and constructions require exact knowledge of the
geophysical properties of the seabed and sub-seabed, as unexpected
objects can slow down or halt projects. This book presents the
state-of-the-art in acoustic exploration of the seabed and
sub-seabed, from initial designs in the 1980s to commercial
contracting and operation of the Acoustic Corer (TM) in the last
decade. The Acoustic Corer (TM) is a high-definition commercial
acoustic sub-bottom imaging system, producing an "acoustic core"
within which sub-seabed sedimentary characteristics and discrete
buried objects larger than 0.5 m can be identified and mapped. It
makes use of the innovative JYG-cross design, inspired by seismic
reflection and uses Synthetic Aperture Sonar (SAS) multi-angle
scattering in and within the seabed to deliver unprecedented
imagery. This book was written by the inventor of these concepts, a
known specialist in seabed acoustics, with help from an experienced
academic and author. It is intended first and foremost as a
"how-to" guide for offshore industries looking at techniques to
make the installation of different types of structures safe and
efficient.
