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.

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.
