This paper is based on material presented at the start of a Health Protection Agency meeting
on ultrasound and infrasound. In answering the question 'what is ultrasound?', it shows that …

Multibeam echosounder systems (MBES) have long provided bathymetric data with high
temporal and spatial resolution. In the last couple of decades, MBES observations of …

This third edition of Reconstructing Quaternary Environments has been completely revised
and updated to provide a new account of the history and scale of environmental changes …

Seabed-hugging flows called turbidity currents are the volumetrically most important process
transporting sediment across our planet and form its largest sediment accumulations. We …

This book is an introduction to the physical processes of cohesive sediment in the marine
environment. It focuses on highly dynamic systems, such as estuaries and coastal seas …

Simulation forms an important part of the development and empirical evaluation of
underwater acoustic network (UAN) protocols. The key feature of a credible network …

In the Erlenbach stream, a pre‐alpine steep channel in Switzerland, sediment transport has
been monitored for more than 25 years. Near the confluence with the main valley river …

Measurements of flow, turbulence and suspended sediment concentration were carried out
in a tidal creek that acts as a conduit for water and sediment to an intertidal salt marsh. A …

Indirect bedload transport measurements have been made with the Swiss plate geophone
system in five gravel‐bed mountain streams. These geophone sensors record the motion of …

For over two decades, coastal marine scientists studying boundary layer sediment transport
processes have been using, and developing, the application of sound for high temporal …
