应地球科学与资源学院张世红教授邀请，英国利物浦大学Andy Biggin教授将来我校进行学术交流，并作学术报告。 题目：Determining deep Earth Evolution from Paleomagnetism: insights from measurements and models 时间：2024.6.8 16:00-18:00 地点：教4楼 101 报告摘要：Earth’s magnetic field, generated in its liquid outer core, stretches out into space and shields the atmosphere from damaging solar wind radiation. It also leaves a signature of its properties in rocks as they have formed at the surface through much of Earth history. Strong variations in paleomagnetic field behavior evident on timescales exceeding ten million years have the potential to elucidate deep mantle and core evolution processes through their impact on time-averaged outer core convection. Here I will report on efforts led by the group at Liverpool to realize these avenues of potential through obtaining and collating palaeomagnetic measurements and capturing and reproducing these datasets in global models of outer core convection. Insights into such globally significant events as the recent weakening of the magnetic field and its near collapse at the end of the Precambrian will be outlined.
报告人简介：Andy Biggin现为英国利物浦大学地球海洋和环境系教授，国际大科学计划“深时数字地球（Deep-time Digital Earth）”古地磁国际工作组副组长。他2001年获得博士学位。之后在墨西哥国立自治大学（UNAM），蒙彼利埃大学（Montpellier），乌特勒支大学（Utrecht）工作。2009年得到NERC Advanced Fellowship在利物浦大学工作，并于2016年成为教授。 他现在领导着利物浦大学地磁学实验室。他对地球磁场演化有深入研究取得了一系列重要成果，包括35亿年至今的地球磁场绝对古强度研究，以及短时间尺度百年级别地球磁场变化和长时间尺度地球磁场变化。他是Geological Society of London（2018） 和Royal Astronomical Society（1999）会士。他担任国际期刊Geophysical Journal International的主编（2010至今），还担任Scientific Data的编委（2014至今）。迄今他已在Nature, Nature Geoscience, Nature Communications, PNAS, Earth and Planetary Science Letters, Journal of Geophysical Research: Solid Earth, Geophysical Research Letters等国际期刊上发表学术论文 124篇。 欢迎广大师生参加！
