Acoustics Travel Time ASCII CSV data for GNSS-A in Cascadia (2021-2023)

These data files were collected as part of GNSS-A operations on the Cascadia Subduction Zone, and can provide estimates of crustal deformation rates along the plate boundary. The data were collected on missions starting in 2021 by a remotely-operated Wave Glider system. The Wave Glider collects GNSS data while ranging to an array of seafloor transponders. All of the GNSS-A sites are located on the accretionary prism. The acoustics files are ASCII csv files that contain the acoustic ranges and QC metrics for each acoustic reply received by the Wave Glider. There is one acoustics file for each transponder in an array for a given survey, and the file names contain the site, year, Wave Glider, and unique ID of the transponder. The files were generated with NSF funding as part of the project called Constraints on Interseismic Locking near the Trench on the Oregon Segment of the Cascadia Subduction Zone Using Seafloor Geodesy (GNSS-A), funded with NSF awards OCE21-27140 and OCE21-26396.

这些数据文件是卡斯卡迪亚俯冲带（Cascadia Subduction Zone）GNSS-A作业的一部分，可提供板块边界地壳形变速率的估算数据。数据由远程操控的Wave Glider系统于2021年起通过多次任务采集。Wave Glider在对海底应答器阵列进行测距的同时采集GNSS数据。所有GNSS-A站点均位于增生楔上。声学文件为ASCII格式的CSV文件，包含Wave Glider接收的每个声学应答的声学测距数据及质量控制（QC）指标。对于特定测量任务，阵列中的每个应答器对应一个声学文件，文件名包含站点、年份、Wave Glider及应答器的唯一标识符。这些文件由美国国家科学基金会（NSF）资助生成，是“利用海底大地测量（GNSS-A）约束卡斯卡迪亚俯冲带俄勒冈段海沟附近的震间闭锁”项目的一部分，该项目获得NSF奖项OCE21-27140和OCE21-26396资助。
