Underwater robot could help in search and rescue

One use for a robot like this is during underwater search and rescue operations. The robot modules could split up and search for survivors and recombine to lift heavy objects and open a passageway.
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.

Elephant seals monitor ocean health

Elephant seals measure oxygen content of ocean

Diving almost continuously at great depth during most of the year, and covering large distance through remote areas of the Southern Ocean, Kerguelen elephant seals have proved to be a great alternative to other instruments for monitoring the oceans. The seal-derived measurements of oceanic dissolved oxygen give better results than other methods, according to new research.
