Remotely-sensed iceberg geometries and meltwater fluxes

This dataset includes manually-extracted iceberg geometries and meltwater fluxes from 2011-2022 WorldView digital elevation model time series for 15 study sites around Antarctica. Each file contains the coordinates, median surface elevation, density, volume, surface area, draft, and submerged area estimated for an iceberg on two different observation dates (specified in the file name). The submarine meltwater flux for each iceberg, calculated as the volume change over time corrected for surface mass balance processes and creep thinning between observation dates, is provided for each iceberg. Dates listed in file names are in YYYYMMDDhhmmss format. Site abbreviations in file names are as follows: BG = Blanchard Glacier, CG = Cadman Glacier, FG = Ferrigno Glacier, FI = Filchner Ice Shelf, HG = Heim Glacier, LA = Edgeworth Glacier (Larsen A tributary), LB = Cadman Glacier (Larsen B tributary), LG = Leonardo Glacier, MI = Mertz Ice Tongue, PT = Polar Times, RI = Ronne Ice Shelf, SG = Seller Glacier, TG = Thwaites Glacier, TI = Totten Ice Shelf, and WG = Widdowson Glacier.本数据集包含从2011-2022年WorldView数字高程模型时间序列中手动提取的南极周边15个研究区域的冰山几何形态与融水通量数据。每个文件包含两次不同观测日期（文件名中注明）下某座冰山的坐标、表面高程中位数、密度、体积、表面积、吃水深度以及淹没面积估算值。针对每座冰山，本数据集还提供了其水下融水通量数据：该通量通过计算两次观测期间的体积变化，并校正了地表质量平衡过程与冰体蠕变减薄效应后得到。文件名中标注的日期采用YYYYMMDDhhmmss格式。文件名中涉及的站点缩写对应关系如下：BG = 布朗查德冰川(Blanchard Glacier)，CG = 卡德曼冰川(Cadman Glacier)，FG = 费里尼奥冰川(Ferrigno Glacier)，FI = 菲尔希纳冰架(Filchner Ice Shelf)，HG = 海姆冰川(Heim Glacier)，LA = 埃奇沃斯冰川(Edgeworth Glacier)（拉森A支流），LB = 卡德曼冰川(Cadman Glacier)（拉森B支流），LG = 莱昂纳多冰川(Leonardo Glacier)，MI = 默茨冰舌(Mertz Ice Tongue)，PT = 极地时报(Polar Times)，RI = 龙尼冰架(Ronne Ice Shelf)，SG = 塞勒冰川(Seller Glacier)，TG = 思韦茨冰川(Thwaites Glacier)，TI = 托滕冰架(Totten Ice Shelf)，WG = 威多森冰川(Widdowson Glacier)。
