The propagation of underwater sound waves through a random distribution of ice blocks is studied as a numerical simulation problem. For a sparse distribution of ice blocks, it looks like a scattering ...

A laser-equipped research platform has, for the first time, photographed airflow just millimeters above ocean waves, ...

Using an innovative laser measurement system, previously unknown and highly complex mechanisms of energy exchange between ...

Fisheries acoustics uses sound waves to detect who's swimming through Maine's waters. At its core, fisheries acoustics is essentially a really "fancy fish finder," says Aaron Whitman, a senior ...

Various analog situations in acoustics and electromagnetic waves are described. Certain higher order modes of airborne sound waves in tubes possess a transverse or polarized nature, and ...
