Underwater robots give unique Arctic insight

SAMS press release: 8 June 2018

 

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) in Oban 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.

 

The gliders can also measure chlorophyll, an indication of the biological content of the water, and a rapid increase in the chlorophyll levels in mid-April this year showed the moment the spring bloom began. The data could help predict how the Arctic ecosystem will respond to climate change.
