Onshore-offshore surveying and monitoring of selected arctic coastal areas of Nunavut, 2006-2009

Coastal data were collected in the summers of 2006 to 2009 for two main purposes; 1) to characterize the morphology and sedimentology of raised-beach sequences on Lowther Island, and 2) to monitor and characterize the morphology, evolution and processes of modern coasts across a longitudinal gradient in Nunavut. More precisely, the intention is to study the impact of changes in relative sea level and sea-ice duration and concentration on gravel beach morphodynamics.

本数据集的海岸数据采集于2006至2009年夏季，主要服务于两项核心研究目标：1）对洛瑟岛（Lowther Island）上的抬升海滩序列（raised-beach sequences）的地貌特征与沉积学特征进行系统性刻画；2）对努纳武特地区（Nunavut）沿纵向梯度分布的现代海岸的地貌形态、演化过程与动力机制开展监测与特征刻画。更具体而言，本研究旨在探究相对海平面变化、海冰持续时长与浓度变化对砾石海滩地貌动力过程（gravel beach morphodynamics）的影响。
