Koester, Alexandria Jo. « Rapid thinning of the Laurentide Ice Sheet in coastal Maine, USA during late Heinrich Stadial 1 : ». Thesis, Boston College, 2017. http://hdl.handle.net/2345/bc-ir:107308.
Texte intégralFew data are available to infer the thinning rate of the Laurentide Ice Sheet (LIS) through the last deglaciation, despite its importance for constraining past ice sheet response to climate warming. We measured 31 cosmogenic 10Be exposure ages in samples collected on coastal mountainsides in Acadia National Park and from the slightly inland Pineo Ridge moraine complex, a ~100-km-long glaciomarine delta, to constrain the timing and rate of LIS thinning and subsequent retreat in coastal Maine. Samples collected along vertical transects in Acadia National Park have indistinguishable exposure ages over a 300 m range of elevation, suggesting that rapid, century-scale thinning occurred at 15.2 ± 0.7 ka, similar to the timing of abrupt thinning inferred from cosmogenic exposure ages at Mt. Katahdin in central Maine (Davis et al., 2015). This rapid ice sheet surface lowering, which likely occurred during the latter part of the cold Heinrich Stadial 1 event (19-14.6 ka), may have been due to enhanced ice-shelf melt and calving in the Gulf of Maine, perhaps related to regional oceanic warming associated with a weakened Atlantic Meridional Overturning Circulation at this time. The ice margin subsequently stabilized at the Pineo Ridge moraine complex until 14.5 ± 0.7 ka, near the onset of Bølling Interstadial warming. Our 10Be ages are substantially younger than marine radiocarbon constraints on LIS retreat in the coastal lowlands, suggesting that the deglacial marine reservoir effect in this area was ~1,200 14C years, perhaps also related to the sluggish Atlantic Meridional Overturning Circulation during Heinrich Stadial 1

Texte intégralThe marine West Antarctic ice sheet is characterized by being largely in contact with the ocean. The latest observations reveal an acceleration in its mass loss over the last few decades, mainly due to increased melting under floating ice shelves. However, its future evolution remains highly uncertain, due to our poor understanding of the physical processes at play between the ice sheet and the ocean.The last deglaciation (21 ka-11 ka) is one of the most recent major climatic changes in our history. This period is marked by an increase in global atmospheric temperatures and the melting of the North American and Eurasian ice sheets. The study of the Barents-Kara Ice Sheet (BKIS), which covered the Barents and Kara Seas during the Last Glacial Maximum (LGM, 21 ka) and was an integral part of the Eurasian Ice Sheet, is of particular interest because of its common features with present-day West Antarctica. Identifying the mechanisms responsible for its retreat allows to provide information to better understand the West Antarctic behavior within under present and future climatic conditions.The impact of climate on the evolution of a marine ice sheet depends on two main processes: The surface mass balance, depending on atmospheric temperatures and precipitation, and melting under floating ice, related to oceanic temperatures and salinity. In order to identify the mechanisms triggering the BKIS retreat, I used the GRISLI2.0 ice-sheet model to analyse the ice-sheet response to climate perturbations at the LGM. This study highlighted the key role of atmospheric temperatures in triggering the melting of the ice sheet via surface melting, while ocean temperatures had only a limited impact despite a large part of BKIS being in contact with the ocean. I also identified that the total retreat of BKIS could be attributed to a mechanical instability at the grounding line, caused by a decrease in ice thickness resulting from an increase in surface melting.In order to better understand the impact of ice sheets on the global climate, I have also carried out the first transient simulation of the last deglaciation with the IPSL-CM5A2 model, modifying the geometry of the ice sheets provided by the GLAC-1D reconstruction at some key periods. The simulations show a warming trend in line with the reconstructions, particularly during MWP1A, which was characterised by an abrupt rise in atmospheric temperatures. Using sensitivity experiments, I have shown that changes in the ice sheet geometry have contributed to the increase in atmospheric temperatures via temperature-altitude feedbacks and the albedo effect. Moreover, I have shown that ocean dynamics have been significantly altered by freshwater fluxes from the melting ice sheets. This has led to a weakening of the strength of the Atlantic Meridional Overturning Circulation and a reduction of its deepening, resulting in a warming slowdown, mainly located in the North Atlantic Ocean. In addition, the IPSL-CM5A2 experiments all simulate a shutdown of the Antarctic bottom water circulation at the onset of MWP1A, leading to a significant cooling of about 100 years in the Amundsen Sea, followed by a restart of this circulation.This work is contributing to a better understanding of the complex mechanisms governing the dynamics of the ice sheets and their interaction with the climate, while also providing a basis for anticipating the consequences of current and future climate change, particularly in West Antarctica
