摘要

Abstract >Drumlins are subglacial bedforms streamlined in the direction of ice flow. Common in deglaciated landscapes, they have been widely studied providing rich information on their internal geology, size, shape, and spacing. In contrast with bedform investigations elsewhere in geomorphology (aeolian and fluvial dunes and ripples for example) most drumlin studies derive observations from relict, and thus static features. This has made it difficult to gain information and insights about their evolution over time, which likely hampers our understanding of the process(es) of drumlin formation. Here we take a morphological approach, studying drumlin size and spacing metrics. Unlike previous studies which have focussed on databases derived from entire ice sheet beds, we adopt a space‐for‐time substitution approach using individual drumlin flow‐sets distributed in space as proxies for different development times/periods. Framed and assisted by insights from aeolian and fluvial geomorphology, we use our metric data to explore possible scenarios of drumlin growth, evolution and interaction. We study the metrics of the size and spacing of 36 222 drumlins, distributed amongst 71 flow‐sets, left behind by the former British‐Irish Ice Sheet, and ask whether behaviour common to other bedform phenomena can be derived through statistical analysis. Through characterizing and analysing the shape of the probability distribution functions of size and spacing metrics for each flow‐set we argue that drumlins grow, and potentially migrate, as they evolve leading to pattern coarsening. Furthermore, our findings add support to the notion that no upper limit to drumlin size exists, and to the idea that perpetual coarsening could occur if given sufficient time. We propose that the framework of process and patterning commonly applied to non‐glacial bedforms i </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div

drumlins在冰流方向上流线型底透镜叶片。常见的景观中，他们已被广泛研究提供有关其内部地质，尺寸，形状和间距的丰富信息。相反，与在地貌（Aeolian和河流沙丘和涟漪中的其他地方的钻石调查相比，大多数Drumlin研究都会导出依赖的观察，从而导致静态特征。这使得难以随着时间的推移获得对他们的演变的信息和见解，这可能妨碍了我们对鼓中形成过程的理解。在这里，我们采取了形态学方法，研究了鼓风尺寸和间距度量。与以往的研究不同，这些研究侧重于来自整个冰床床的数据库，我们采用了一种空间替换方法，使用在空间中分布在空间中的单独的Drumlin流量，以进行不同的开发时间/期间。来自Aeolian和河流性地貌的见解框架和协助，我们使用我们的公制数据来探索Drumlin成长，进化和互动的可能场景。我们研究了36 222号Drumlins的规模和间隔的指标，分布在71个流套中，由前英国爱尔兰冰盖留下，并询问是否可以通过统计分析来衍生出其他床位现象的行为。通过表征和分析每个流量集的大小和间距度量的概率分布函数的形状，我们认为鼓lins生长，并且可能迁移，因为它们的发展导致图案粗化。此外，我们的研究结果增加了对概念的概念，即在给定足够的时间时，可能会发生令人瞩目的概念。我们建议的过程和图案框架通常适用于非冰川床形I
