Assessing the Contribution of Antarctic Peninsula Glaciers to Global Sea Level Rise

该项目利用卫星数据、人工智能和先进的数值技术，为评估南极半岛冰川对全球海平面上升的贡献提供了令人兴奋的机会。格陵兰岛和南极洲冰盖的融化造成了全球海平面上升的三分之一以上。南极半岛是变化最迅速的极地地区之一，在20世纪下半叶，它是地球上变暖最快的地区之一。该地区的气温升高导致了冰川学的快速变化，包括冰架崩塌、冰加速融化并排放到南大洋，以及近几十年来该地区对海平面的贡献增加了两倍。卫星为监测气候变化的影响提供了独特的工具。然而，在南极半岛等偏远的极地地区进行可靠的测量是极具挑战性的，因为地形复杂，而且有许多小的、高度动态的冰川。卫星技术的最新进展现在提供了对整个地区的冰川变化进行新的、可靠的估计的潜力。该项目旨在利用新的卫星数据流和创新的人工智能和计量技术，监测整个南极半岛的冰川演变，并评估其对海平面上升的贡献。具体目标是：(1)利用美国宇航局的ICESat-2卫星和高分辨率雷达高度计的测量结果对冰川变化进行新的估计；(2)确定区域质量损失，包括对不确定性的严格处理。该项目是CASE奖学金，这意味着学生将受益于英国国家物理实验室专家的额外监督，涉及计量和不确定度分析。您还将成为英国极地观测和建模中心以及兰开斯特大学- ukceh环境数据科学卓越中心的成员，并有广泛的机会与冰川学家，气候科学家和数据科学家合作。

This project offers the exciting opportunity to assess the contribution of Antarctic Peninsula glaciers to global sea-level rise, using satellite data, A.I. and advanced numerical techniques.Melting of the Greenland and Antarctica ice sheets contributes more than one third of global sea-level rise. One of the most rapidly changing polar regions is the Antarctic Peninsula which, during the second half of the 20th Century, was one of the fastest warming regions on Earth. Temperature increases across this region have led to rapid glaciological change, including ice shelf collapse, accelerated ice melting and discharge into the Southern Ocean, and a tripling of the region's contribution to sea-level in recent decades. Satellites provide a unique tool for monitoring the impact of climate change. However, making reliable measurements in remote polar regions such as the Antarctic Peninsula is highly challenging, due to the complex terrain and multitude of small, highly dynamic glaciers. Recent advances in satellite technology now offer the potential to develop new, robust estimates of glacier change across this region. This project aims to utilize new streams of satellite data and innovative A.I. and metrological techniques, to monitor glacier evolution across the Antarctic Peninsula and assess its contribution to sea-level rise. Specific aims are to (1) develop new estimates of glacier change using measurements from NASA's ICESat-2 satellite and high-resolution radar altimeters, and (2) determine regional mass loss, including rigorous treatment of uncertainty.This project is a CASE studentship, meaning that the student will benefit from additional supervision by experts atthe UK's National Physical Laboratory, relating to metrology and uncertainty analysis. You will also become a member of the UK Centre for Polar Observation and Modelling and the Lancaster University-UKCEH Centre of Excellence in Environmental Data Science, with extensive opportunities to collaborate with glaciologists, climate scientists, and data scientists.
