This is the best summary I could come up with:

The Scottish Association for Marine Science (Sams) at Oban is deploying the robots on autonomous missions between the UK and Iceland over five months.

Atlantic circulation is important for distributing tropical heat across the world and keeps northern Europe at a more temperate climate than other locations on the same latitude.

Oceanographer Helen Smith says the marine environment is incredibly understudied because most historical observations are confined to the area surrounding a ship at a single point in time, usually the summer.

Prof Mark Inall, an expert in physical oceanography at Sams, describes the heat in the North Atlantic as a vital part of the earth’s climate system.

As well as monitoring the Amoc, the data gathered by gliders helps improve scientists’ understanding of how the atmosphere is affected by changes in the ocean.

Other robotic technology being used includes an autonomous boat which uses sonar to collect ocean pressure data from sensors on the sea bed.
