Description
Summary:Abstract. The Ter~a Nova Bay polynya is a large, stable, annually recu~ring feature in the western Ross Sea which ma~kedly influences sea ice dynamics and physical oceanography in that region. St~ong, pe~sistent katabatic winds which blow far offshore, and blockage of northward drift i ng sea ice by the Drygalski Ice Tongue are both necessary for polynya ex-istence. Secondary factors, such as katabatic and synoptic wind interactions, and seawater depth, characteristics and circulation also affect the polynya. However, it is the ab-sence of this katabatic-blocking combination along other windy coasts that explains why similar polynyas do not form there. Direct
