Internet of Underwater Things uses the power of light

Researchers in Saudi Arabia are developing a system that can concurrently transmit light and energy to underwater energy devices. Self-powered internet of underwater things...

Underwater Internet coming Soon?

You don't usually find a wireless network whilst underwater, but that may change as researchers develop a deep-sea internet
Seal whiskers

Seal whiskers inspire vortex sensor

Seals use their whiskers to sense food by tracking the vortices left by potential prey, for example by fish swimming.The authors of a...
SENSOR SNIFFS OUT METHANE IN DEEP-SEA VENTS AND COWS

Sensor sniffs out methane in deep-sea vents and cows

Methane is a potent greenhouse gas that traps heat about 20 times more effectively than carbon dioxide.Understanding the sources of methane, and how...
Shoal of Fish

Swimming fish may improve the design of robots

The constant, seemingly random, movement of fish is actually gives them the best sensory feedback they can get to navigate the world, say Johns...
Underwater robot maps sea ice

Submarine robots learn teamwork

Submarine robots will soon work together as a team.Studying the deep ocean floor is cumbersome, expensive and dangerous. The majority of exploration efforts...
At 9 foot long, not including the tail, tiger shark (Galeocerdo cuvier) Harry Lindo is not exactly on the small side. In just over 3 years Harry swam over 44,000 kilometres – that’s more than the circumference of the Earth (just over 40,000 kilometres). Harry’s track is the longest recorded for a tiger shark, and probably the longest ever published for any shark species.

Enhanced underwater robots can boost ocean discoveries

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.

New Sensor Monitors Ocean Acidification

Scientists and engineers have achieved the first step in developing a cost-effective micro sensor for long-term monitoring of ocean acidification.The new technology, that will...
Marine sensing

Underwater sensing with light and sound

Oceanic sensor networks that collect and transmit real-time data could transform our understanding of marine ecology and improve pollution and disaster management. A research...
