SignificanceThe Ice-Free Corridor (IFC) has long played a key role in hypotheses about the peopling of Americas. Earlier assessments its age suggested that IFC was available for Clovis-first migration, but subsequent developments now suggest pre-Clovis occupation Americas occurred before opening IFC, thus supporting Pacific coastal migration route instead. However, large uncertainties existing ages from cannot preclude availability as first migrations. Resolving this debate over is important...
During the last deglaciation, collapse of saddle between North American Cordilleran and Laurentide ice sheets led to rapid ice-sheet mass loss separation, with meltwater discharge contributing deglacial sea-level rise. We directly date separation at end using 64 10Be exposure ages along an ∼1200-km transect suture zone. Collapse began in south by 15.4 ± 0.4 ka ended 13.8 0.1 ∼56°N. Ice-sheet model simulations consistent find that contributed 6.2–7.2 m global mean rise from ∼15.5 ∼14.0 ka, or...
Abstract Pine Island Glacier, West Antarctica, is the largest Antarctic contributor to global sea-level rise and vulnerable rapid retreat, yet our knowledge of its deglacial history since Last Glacial Maximum based largely on marine sediments that record a retreat ending in early Holocene. Using suite 10Be exposure ages from onshore glacial deposits directly adjacent we show this major glacier thinned rapidly mid-Holocene. Our results indicate Glacier was at least 690 m thicker than present...
Fieldwork is a pedagogical cornerstone of many geoscience degrees. During the academic years 2019–20 and 2020–21, worldwide COVID-19 pandemic made outdoors fieldwork difficult, resulting in an urgent need to develop virtual alternatives. However, there still more learn about impact teaching virtually on student learning experience. This study aims assess experience during immersive interactive three-dimensional establish value digital techniques improve inclusivity geosciences Quantitative...
