Abstract Glacial lakes are increasing in number and extent under a warming climate. Despite demand for lake monitoring understanding outburst mechanisms, studies of large events sparse. Here we report an Lago Greve, proglacial Chilean Patagonia. During the event April–July 2020, level dropped by 18.3 ± 1.2 m area decreased 14.5 0.02 km 2 . The total water discharge was 3.7 0.2 3 , which is one ...

In unglaciated terrain, the imprint of past glacial periods is difficult to discern. The topographic signature periglacial processes, such as solifluction lobes, may be erased or hidden by time and vegetation, thus their import diminished. Belowground, weathering, particularly frost cracking, have imparted a profound influence on weathering erosion rates during climate regimes. By combining mec...

Terrestrial climate records for Antarctica, beyond the age limit of ice cores, are restricted to few unglaciated areas with exposed rock outcrops. Marine sediments on Antarctica's continental shelves contain past oceanic and terrestrial environments that can provide important insights into Antarctic evolution. The SHALDRIL II (Shallow Drilling Continental Margin) expedition recovered sedimentar...

Abstract. The preservation of cosmogenic nuclides that accumulated during periods prior exposure but were not subsequently removed by erosion or radioactive decay complicates interpretation exposure, erosion, and burial ages used for a variety geomorphological applications. In glacial settings, cold-based, non-erosive glacier ice may fail to remove inventories inherited in glacially transported...

Introduction: The strong geomorphic similarities between lobate deposits 1) on the northwest flank of the Tharsis Montes [1,2] and 2) along the dichotomy boundary between 30° and 50° [3] with terrestrial cold-based glaciers and glacial deposits has led to hypotheses for geologically recent (Amazonian-age) low and mid-latitude glaciation on Mars [1,4]. The key to these studies has been to identi...
