中文摘要
该奖项旨在对挪威北方海岸外的罗弗敦群岛的湖泊进行勘察调查,以确定具有高分辨率古气候研究潜力的湖泊,方法是进行湖沼学和水深测量调查,并从选定地点采集和分析湖泊沉积物的短岩心。 罗弗敦群岛(北大西洋北纬67-69度)所处的位置对挪威海内海洋环流的变化很敏感,它们受到北大西洋涛动大气环流变化的强烈影响。 如果能够找到合适的湖泊沉积物,那么这些海洋和大气环流模式变化的高分辨率沉积记录将是有价值的。
英文摘要
This award is for a reconnaissance investigation of lakes in the Lofoten archipelago, off the coast of northern Norway, to identify lakes with potential for high resolution paleoclimate studies, by carrying out limnological and bathymetric surveys and recovering and analyzing short cores of lacustrine sediments from selected sites. The Lofotens (67-69 degrees N in the North Atlantic) are in a location that is sensitive to changes in ocean circulation within the Norwegian Sea, and they are strongly influenced by variations in atmospheric circulation through the North Atlantic Oscillation. If the proper lake sediments can be found, high-resolution sedimentary records of changes in these ocean and atmospheric circulation patterns would be valuable.
