The world's oceans cover 71% of the Earth's surface, yet, they are the least understood and most vulnerable resource we have on the planet.
We desperately need to know more about relationship between the oceans and climate change. Ocean acidification is one of the most serious threats to our planet and we have not begun to properly understand its causes or effects.
Traditionally, large ships have been used to take measurements, however, these ships are very expensive and burn huge amounts of polluting diesel fuel during their operations.
Unmanned vehicles, like gliders, and drifting bouy's have recently been deployed with promising results, however they are very slow (~1knots) and still require a ship to deliver them to their start location.
