| After that, oil will spread to the marine environment by ice break-up, lead formations, or polynya. |
|
| The most important floe-edge and moving-ice habitats are distributed in a band through the Bathurst polynya. |
|
| The continual production of new and young ice in the North Water polynya contributes greatly to the roughness of ice in northern Baffin Bay. |
|
| Given the importance of the ice bridge in the formation and maintenance of the polynya this approach is seen as an important contribution to the future monitoring of the NOW region. |
|
| The concept that a polynya is analogous to the 'Canary in the Coal Mine' is seductive, and in the case of the NOW Polynya may in fact be a reasonable premise. |
|
| Similarly, where a water surface is available, such as a polynya or a shore or flaw lead, there is also greatly enhanced absorption of incoming radiation. |
|
| These imageprocessing techniques show promise as a means of obtaining unambiguous estimates of the range of ice types typical of an arctic polynya. |
|
| Processes of ice growth also 'feedback' into the atmosphere and the ocean through the phase changes associated with the ice cover within the polynya. |
|
| Polynya, also spelled polynia, a semipermanent area of open water in sea ice. |
|
| Polynyas, and in particular the NOW Polynya, are known to be areas of high sustained biological production due to the early removal of the sea-ice cover. |
|
| The NOW Polynya is of sufficient size that it is possible to mount a detailed field sampling program using a combination of ocean moorings, icebreaker and fast-ice based sampling schemes. |
|
| As early as the 16th century, many prominent people correctly believed that the North Pole was in a sea, which in the 19th century was called the Polynya or Open Polar Sea. |
