Sea robots show Arctic climate change

Underwater robots have uncovered new evidence about life in the Arctic and, for the first time, revealed the moment the region's marine ecosystem springs into life after the dark winter season.
The unique data was gathered by autonomous ocean-going 'gliders' and will help marine scientists understand more about the so-called 'Arctic spring bloom', which kick-starts the ecosystem and is crucial in providing food for animals in the region.
Gliders work around the clock for months on end, taking measurements such as ocean temperature, oxygen levels and salinity. Researchers from the Scottish Association for Marine Science (SAMS) have been able to observe seasonal changes as they happen in the Arctic, thanks to a continuous glider presence in the Barents Sea between January and July this year.
