SEALS have helped gather a decade of information from some of the harshest polar environments inaccessible to man after they were "tagged" by scientists.
The data collected from the remote and icy seas will now be made available to academics around the world.
Since 2004, a "small army" of seals wearing sensors designed and made at the Sea Mammal Research Unit at St Andrews University has produced nearly 400,000 environmental profiles of the Southern Ocean.
The sensors are said to be non-invasive and fall off when the seals moult, and the university said they are the only devices of their kind that can be attached to animals.
The tags sent short pieces of information periodically back to researchers via satellites, in a process likened to tweeting.
The data was then processed in St Andrews and shared with international scientists and the Met office for use in weather forecasting.
Dr Lars Boehme, a lecturer at the University of St Andrews, said: "The information sent back to us gives us details about the seal's immediate physical environment. It's like tweeting.
"Changes in the polar oceans have global ramifications and a significant influence on weather and climate. Sustained observations are required to detect, interpret and respond to change and a strategic system of observations combining a range of platforms is critical in maintaining the flow of information."
The portal containing the decade of data, named Marine Mammals Exploring the Oceans Pole-to-Pole, is launched today.
Mike Fedak, a professor of biology at the university, said: "The fact that animals have collected the data is an interesting innovation in ocean observation.
"But perhaps of more general importance is that data from these remote and inaccessible places now gives us a much clearer picture of the state of the world's oceans.
"We have shown that data from these far-flung locations is critical to understanding the broader state of the global ocean."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
