Recent evidence has shown increasing mass loss from the Greenland ice sheet, with a general trend of accelerated mass losses extending northwards. However, different glaciers have been shown to respond differently to similar external forcings, constituting a problem for extrapolating and upscaling data. Specifically, whilst some outlet glaciers have accelerated, thinned, and retreated in response to atmospheric and oceanic warming, the behavior of other marine terminating glaciers appears to be less sensitive to climate forcing. Ryder glacier, for which only a few studies have been conducted, is located in North Greenland and terminates with a floating ice tongue in Sherard Osborn Fjord. The persistence or disintegration of floating ice tongues has impacts on glacier dynamics and stability, with ramifications beyond, including sea level rise. This study focuses on understanding the controls on calving and frontal ablation of the Ryder glacier through the use of time‐lapse imagery and satellite data. The results suggest that Ryder glacier has behaved independently of climate forcing during recent decades, with fjord geometry exerting a first order control on its calving.

在北格陵兰岛莱德冰川产犊

最近的证据表明，格陵兰冰盖的质量损失增加了，加速质量损失的总体趋势是向北延伸。但是，已经显示出不同的冰川对相似的外部强迫有不同的响应，这为数据的外推和放大带来了问题。具体而言，尽管一些出口冰川因大气和海洋变暖而加速，变薄和退缩，但其他海洋终止冰川的行为似乎对气候强迫不太敏感。莱德冰川（仅进行了少量研究）位于北格陵兰，在谢拉德·奥斯本峡湾（Sherard Osborn Fjord）以漂浮的冰舌终止。漂浮的冰舌的持久性或崩解会影响冰川的动力学和稳定性，其后果是包括海平面上升在内。这项研究的重点是通过使用延时图像和卫星数据来了解莱德冰川的产犊和额叶消融的控制。结果表明，莱德冰川在近几十年来的表现与气候强迫无关，峡湾的几何形状对其产犊产生了一级控制作用。
