Overview

This work addresses the findings from actively researched polynyas and reports on the new understandings of polar systems that have evolved from these studies. It includes topics from meteorology to physics to biology and chemistry, and seeks to integrate them into a synthetic assessment. It provides material from both the Arctic and Antarctic, which is highly unusual in books of this type. Polynyas are relatively ice-free regions compared to the areas around them and have been suggested as being the focus for energy transfer between the atmosphere and ocean, ice factories and critical areas with respect to polar ecosystems and biogeochemical cycles. This volume presents an integrated, multidisciplinary review of polynyas in both the Arctic and Antarctic. It emphasizes the meteorology, ice dynamics, oceanography, biological components, chemistry and modelling of these systems, particularly with respect to their roles in polar processes and distributions. The various interactions within polynyas are emphasized, as are the potential changes in polynyas that might occur under a climate regime that is rapidly changing.; The authors are leaders in polynyaresearch and all are internationally recognized. An area of open water in pack ice or sea ice. They may be kept open by constant winds or the upwelling of water, so tend to recur in the same locations year after year. They are particularly important for wildlife as they allow mammals such as whales and seals to have a breathing hole and give birds access to the sea in order to fish.
