Seismic noise interferometry and Distributed Acoustic Sensing (DAS): Inverting for the firn layer S-velocity structure on Rutford Ice Stream, Antarctica

This dataset contains files including continuous DAS and geophone data and a refracted P wave travel time data collected on Rutford Ice Stream, Antarctica. The seismic data is used to perform seismic noise interferometry. The travel time data is used to perform refraction inversion to get the P wave velocity profile. <br> 1. 7 hours of continuous DAS data (100 Hz sampling): 2020-01-14T00:00:19.598000Zoffset_****.mseed, with offset referring to the distance from the DAS channel to the interrogator. 2. Corresponding 7 hours of vertical component continuous geophone (A000, located at DAS channel offset 570 m) data. 3. Refraction P wave travel time from a geophone array refraction survey.本数据集包含采集于南极洲拉特福德冰流（Rutford Ice Stream）的连续分布式声学传感（DAS, Distributed Acoustic Sensing）与检波器数据，以及折射P波走时数据。其中地震数据可用于开展地震噪声干涉测量研究，走时数据则可通过折射反演获取P波速度剖面。<br>1. 7小时连续分布式声学传感数据（采样率100 Hz）：文件名为2020-01-14T00:00:19.598000Zoffset_****.mseed，其中偏移距（offset）指代DAS信道与解调仪之间的距离。<br>2. 对应7小时的垂直分量连续检波器数据，该检波器编号为A000，布设位置对应DAS信道偏移距570 m处。<br>3. 来自检波器阵列折射测量的折射P波走时数据。
