MARC recordThe hybrid polynya at the northern end of Nares Strait / Thomas L. Kozo.
| Title: | The hybrid polynya at the northern end of Nares Strait / Thomas L. Kozo. |
| Author(s): | Kozo, Thomas L. |
| Date: | 1991. |
| In: | Geophysical Research Letters. (1991.), Vol. 18(11) (1991) |
| Abstract: | Satellite images from November to June 1984 to 1989 show sea-ice arches accompanied by unique polynya patterns in this area. Arches formed by late November but polynya patterns did not stabilize until January, when sea-ice transport through strait usually ceases. Polynyas created to lee of arches were of unusual "hybrid" mix, switching from combined latent and sensible heat type in autumn to "pure" sensible heat type in winter. Early in polynya formation, sea ice is removed through temporarily open strait, while ice arch to north blocks ice from drifting into polynya. When strait freezes, newly formed ice cannot be transported downstream. Polynya then begins to freeze, but ice growth is still moderated, apparently due to upward vertical mixing of warmer, more saline water generated by tidal currents flowing over shallow seabed north-west of Robeson Channel. |
