Underwater robots are regularly used by the oil and gas industry to inspect and maintain offshore structures. The same machines could be adapted to gather environmental information, providing substantial benefits to science and to resource companies in the long-term.

Researchers have created a device that can swiftly analyse microbes in oceans, revealing the health of these organisms - too tiny to be seen by the naked eye - and their response to threats to their ecosystems.

A pioneering system for building artificial reefs is ideal for restoring complex marine environments. One of its most important roles is to help protect vulnerable fish stocks and other marine species whose habitats are at risk.

Seals use their whiskers to sense food by tracking the vortices left by potential prey, for example by fish swimming. The authors of a soon-to-be-published paper have used observations of seals to build a 3-D printed sensor that can be...

Oceanographic research projects often deploy underwater sensor systems in the sea. These are retrieved from deep water by remotely releasing them from their moorings. However, the mooring anchor, shackles and cables can not be easily recovered. Australian engineers have therefore...

At 9 foot long, not including the tail, tiger shark (Galeocerdo cuvier) Harry Lindo is not exactly on the small side.  It’s not Harry’s size that is exciting scientists and shark enthusiasts, nor a photograph taken in 2009 by Ian...
