2013 Time lapse photography of Helheim glacier (NERC grant NE/I007148/1)

These high resolution high-oblique time-lapse images were collected in hourly intervals from 5 locations around Helheim glacier in SE Greenland in the summer of 2013. Three cameras (Cameras 1, 2 and 3) were aimed at the calving front ~3.5 km down glacier from the calving front and two cameras (Cameras 4 and 5) were aimed cross-glacier ~3 km up glacier from the calving front. The images are in two stereo groups allowing the extraction of 3D data with significant processing though there are some optical issues that will degrade quality.

本数据集收录了2013年夏季从格陵兰东南部赫拉姆冰川周边五处地点，以每小时间隔收集的高分辨率斜视延时摄影图像。其中，三台相机（相机1、2和3）对准冰川消融前沿下方约3.5公里的冰川前沿，另两台相机（相机4和5）则横跨冰川对准消融前沿上方约3公里的位置。这些图像分为两组立体图像，虽然通过复杂处理可以提取三维数据，但仍存在一些光学问题，将降低图像质量。相关已发表论文链接如下：1. 格陵兰冰川 tidewater 冰川2000-2010年广泛退缩。链接：http://dx.doi.org/10.1657/AAAR0014-049 2. 格陵兰东南部赫拉姆冰川非 grounded 边缘冰川消融动力学。链接：http://dx.doi.org/10.1002/2015JF003531 3. 冰山消融期间的冰川反向运动及其引发冰川地震的原因。链接：http://dx.doi.org/10.1126/science.aab0460 4. 高分辨率传感器网络监测冰川动力学。链接：http://dx.doi.org/10.1109/JSEN.2014.2348534 5. 在冰川消融中浮力弯曲的作用。6. 浮力弯曲控制了赫拉姆冰川在夏季的动态质量损失。链接：http://dx.doi.org/10.1109/JSEN.2014.2348534
