The Arctic Ocean
With much of it covered in ice all year round and with no daylight from October to March, the Arctic Ocean is one of the world's most remarkable oceans. It's home to a multitude of unique life forms, all highly adapted to cope with the extreme and seasonal conditions. The impacts of climate change are more strongly felt here than anywhere else in the world.
Examining the pack ice
The frozen pack ice in the Arctic Ocean makes it one of the most inaccessible oceans in the world. For this reason, most scientific research on pack ice is carried out remotely using satellite imagery and computer modelling. So any opportunity to examine the ice physically will be beneficial to scientific research.
Working out the ice's age is crucial to understanding how well the ice cap as a whole is faring. Any ice that's existed for more than one year, known as multi-year ice and usually more than 2m thick, is a good sign. Any ice less than 2m thick with high salinity levels (salt leaches out of ice over time) is almost definitely first year ice.
|Importance:||Finding out the age of ice first hand will enable scientists to determine the quality of data they receive from satellite imagery and computer modelling.|
|Dive category:||Diving under drifting pack ice is one of the most hazardous forms of diving possible. It must only be attempted by highly qualified and experienced dive teams.|
|Access:||Very few people have been this far north. A site like this can be accessed only by an ice-breaker or by air.|
