The SYNICE project seeks to improve the understanding of pan-Arctic and North Atlantic climate and human systems through the integration and syntheses of several sea-ice data sets together with information from the physical and social sciences. The project is analyzing data from the past 1000 years, with major emphasis on the period c. AD 1800 to the present. Five major locations/sea-ice data sets are being considered: i) The sea-ice record from Iceland; ii) The sea-ice record from the Barents Sea area; iii) The record of historical ice conditions around Newfoundland and on the Grand Banks, and in the Gulf of St. Lawrence and the Scotian Shelf; iv) The Odden region of the central Greenland Sea; v) A climate and sea-ice record based on Moravian missionary accounts from Nain, Labrador. Two other components will investigate local knowledge of sea-ice and other climate changes, specifically in Iceland and Labrador/Nunatsiavut. Deliverables include: i) Development of a new 150-year central Greenland Sea ice-atmosphere dataset; ii) Analysis and modeling of the relationship between ice extent and production in the Central Greenland Sea and the occurrence of deep convection; iii) An interpretation of how Greenland Sea convection has varied over the past 150 years, together with implications of this for the development of ocean changes and marine climate in the Nordic Seas during this period; iv) A homogeneous and reliable long-term sea-ice record for Iceland; v) A synthesis of the sea-ice records with circulation data in order to gain insights into past, present and future natural climate variability of pan-Arctic systems; and vi) a study of the social impacts of changing Arctic and Subarctic environments.

SYNICE项目力求通过综合和综合若干海冰数据集以及来自物理和社会科学的信息，提高对泛北极和北大西洋气候和人类系统的了解。该项目正在分析过去1000年的数据，主要侧重于公元1800年至今的数据。正在审议五个主要地点/海冰数据集：一)冰岛的海冰记录；二)巴伦支海地区的海冰记录；三)纽芬兰周围、大浅滩、圣劳伦斯湾和斯科蒂安大陆架的历史冰情记录；四)格陵兰海中部的奇登地区；五)根据拉布拉多纳恩的摩拉维亚传教士账户编制的气候和海冰记录。另外两个组成部分将调查当地对海冰和其他气候变化的了解，特别是在冰岛和拉布拉多/努纳西亚武特。交付成果包括：1)开发新的150年格陵兰中部海冰-大气数据集；2)分析和模拟格陵兰中部海冰范围与生产和发生深对流之间的关系；3)解释格陵兰海对流在过去150年中的变化，及其对这一时期北欧海洋变化和海洋气候的影响；4)冰岛统一和可靠的长期海冰记录；(V)综合海冰记录和环流数据，以便深入了解泛北极系统过去、现在和未来的自然气候变异性；(Vi)研究北极和亚北极环境变化的社会影响。
