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.

该项目提供了一个令人振奋的机会，利用卫星数据、人工智能和先进的数值技术来评估南极半岛冰川对全球海平面上升的贡献。格陵兰和南极洲冰盖的融化对全球海平面上升的贡献超过三分之一。变化最快的极地之一是南极半岛，在20世纪下半叶，它是地球上变暖最快的地区之一。整个区域的气温上升导致了冰川的迅速变化，包括冰架坍塌，冰加速融化并流入南大洋，近几十年来该区域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，由于复杂的地形和众多小型、高度动态的冰川，在南极半岛等偏远极地地区进行可靠的测量具有极大的挑战性。卫星技术的最新进展现在为开发新的、强有力的对整个地区冰川变化的估计提供了可能性。该项目旨在利用新的卫星数据流以及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NASA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，以及(2)确定区域质量损失，包括对不确定性的严格处理。这个项目是一个案例学生，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，与计量学和不确定度分析有关。您还将成为英国极地观测与建模中心和兰开斯特大学-英国环境数据科学卓越中心的成员，有大量机会与冰川学家、气候科学家和数据科学家合作。
