Collaborative Research: Syntheses of Sea-Ice, Climate and Human Systems in the Arctic and Subarctic [SYNICE]

SYNICE项目旨在通过整合和综合若干海冰数据集以及来自自然科学和社会科学的信息，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，重点是公元1800年至今的数据。正在考虑五个主要地点/海冰数据集：i)冰岛的海冰记录；ii)巴伦支海域的海冰记录；iii)纽芬兰周围、大浅滩、圣劳伦斯湾和苏格兰陆架的历史冰况记录；（四）格陵兰海中部的奥登地区；(5)根据来自拉布拉多省纳因的摩拉维亚传教士的记录得出的气候和海冰记录。另外两个部分将调查当地对海冰和其他气候变化的认识，特别是在冰岛和拉布拉多/努纳茨武特。可交付成果包括：i)开发新的150年格陵兰中部海冰大气数据集；(2)格陵兰海中部冰量和冰量与深对流发生关系的分析和模拟；iii)对过去150年来格陵兰海对流变化的解释，以及这一变化对这一时期北欧海海洋变化和海洋气候发展的影响；冰岛的均匀和可靠的长期海冰记录；v)海冰记录与环流数据的综合，以便深入了解泛北极系统过去、现在和未来的自然气候变率；6)北极和亚北极环境变化的社会影响研究。

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.
