资源简介:
This directory contains the Internal Layer Continuity Index returns when averaged over 100 traces and 1000 traces across a portion of the BAS-AGAP North, Lambert Glacier, East Antarctica. The directory also contains 'Traced buckle reflectors picks from the fold feature found along the shear margin of Lambert Glacier, East Antarctica The three sets of information are provided as: > ”AGAPall100.csv”  > ”AGAPall1000.csv”  csv attributes: (1)   ‘Line_name’: flight name (2)   'X’: projected X and Y coordinates (Polar Stereographic, EPSG: 3031) (3)   'Y’: projected X and Y coordinates (Polar Stereographic, EPSG: 3031) (4)  ‘TraceNr’: Trace number for the chirp radar data (x axis) (5)  ‘ILCI’: Internal Layer Continuity Index output.  > ” Traced_buckle_reflectors.csv”  csv attributes: (1)  ‘Line_name’: flight name (2)  ‘Horizon_name’: Englacial reflector horizon name associated with the flight name. (3)   'X’: projected X and Y coordinates (Polar Stereographic, EPSG: 3031) (4)   'Y’: projected X and Y coordinates (Polar Stereographic, EPSG: 3031) (5)  ‘TraceNr’: Trace number for the chirp radar data (x axis) (6)  ‘Z(ms)’: Depth of the picked horizon (BAS System) (units: microseconds) (7)  ‘Depth(m)’: Depth of the picked horizon (units: metres) (8)  ‘IceThickness(m)’: Ice thickness (units: metres)

本目录收录了针对南极洲东部BAS-AGAP北部的Lambert冰川区域,通过对100条和1000条轨迹的平均计算得到的内部层连续性指数(Internal Layer Continuity Index)。此外,该目录还包含了沿Lambert冰川剪切边缘发现的褶皱特征中的追踪弯曲反射器的拾取数据。所提供的三组信息如下: > “AGAPall100.csv” > “AGAPall1000.csv” CSV属性包括: (1) ‘Line_name’:航次名称 (2) ‘X’:投影X和Y坐标(极地正射投影,EPSG: 3031) (3) ‘Y’:投影X和Y坐标(极地正射投影,EPSG: 3031) (4) ‘TraceNr’:声波雷达数据的轨迹编号(x轴) (5) ‘ILCI’:内部层连续性指数输出。 > “Traced_buckle_reflectors.csv” CSV属性包括: (1) ‘Line_name’:航次名称 (2) ‘Horizon_name’:与航次名称关联的冰内反射器地平线名称。 (3) ‘X’:投影X和Y坐标(极地正射投影,EPSG: 3031) (4) ‘Y’:投影X和Y坐标(极地正射投影,EPSG: 3031) (5) ‘TraceNr’:声波雷达数据的轨迹编号(x轴) (6) ‘Z(ms)’:拾取地平线的深度(BAS系统)(单位:微秒) (7) ‘Depth(m)’:拾取地平线的深度(单位:米) (8) ‘IceThickness(m)’:冰层厚度(单位:米)
