Underwater robot maps sea ice

Underwater robot maps Antactic ice

An underwater robot has enabled researchers to produce the first detailed, high-resolution 3-D maps of Antarctic sea ice. Scientists from the UK, USA and...

GPS signal used for sat-navs could improve knowledge of ocean currents

For the first time sea level has been mapped from space with GPS reflections, according to new research published in Geophysical Research Letters by...

Ocean-Going Robotic Submarine Returns

Scientists are celebrating the first successful deployment and retrieval in Australia of a remotely controlled, deep ocean-going robotic submarine destined to play a central...

Lotus Leaves inspire Net that could Clean Oil Spills

Scientists develop mesh that captures oil but lets water through and could help clean oil spills. The work was partly inspired by lotus leaves, whose bumpy surfaces naturally repel water but not oil.
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.
