Aim Quantify sediment flux in and around the Sor Rondans Mountains in East Antarctica. Objectives Three distinct work packages have been created for this project, to reflect the three distinct methodologies proposed. The objective for each work package is listed below. Objective 1: Quantify landslide hillslope sediment flux in the Sor Rondans Mountains Terrestrial Laser Scanning (TLS) and Structurefrom-Motion (SfM) techniques will be used to survey nunataks in Antarctica, to quantify the volume and frequency of sediment entering the glacial system from subaerial sources. Objective 2: Trace subsurface sediment reflectors through the glacial system Ground Penetrating Radar (GPR) will detect and trace englacial sediment reflectors from local hillslopes, through the glacial system. Analysis of the resultant radargrams will allow sediment entrainment in Antarctica to be studied, providing the first assessment of englacial debris volumes in East Antarctica. Objective 3: Quantify BioFe flux from continental sources to the Southern Ocean. The concentration of BioFe and other essential nutrients in continental Antarctic sediments will be estimated, using landslide derived material collected from a number of field sites. Remote sensing datasets will then be used to map the spatial distribution and flux of BioFe.

目的量化东南极洲索朗丹斯山脉及其周围的沉积物通量。为本项目创建了三个不同的工作包，以反映所提出的三种不同的方法。下面列出了每个工作包的目标。陆地激光扫描（TLS）和运动构造生成（SfM）技术将用于调查南极洲的滑坡，量化从地面来源进入冰川系统的沉积物的体积和频率。探地雷达（GPR）将通过冰川系统探测并追踪当地山坡上的冰川沉积物反射物。对所得雷达图的分析将使人们能够研究南极洲的沉积物夹带，从而首次评估东南极洲的冰川碎片体积。目标3：量化从大陆源流向南大洋的生物fe通量。利用从一些野外地点收集的滑坡产生的材料，将估计南极大陆沉积物中生物硒和其他必需营养素的浓度。然后，遥感数据集将用于绘制生物有机质的空间分布和通量。
