Xeitl Sít’ (LeConte Glacier) acoustic data 2016–2017

### Access All acoustic data files in .wav and .DSG format can be accessed and downloaded from the directory via: [http://arcticdata.io/data/10.18739/A2VD6P67P](http://arcticdata.io/data/10.18739/A2VD6P67P). ### Overview This dataset contains passive underwater acoustic recordings from an autonomous hydrophone (Loggerhead Instruments DSG-ST) moored at a depth of 120 meters (m) in Xeitl Geeyi (LeConte Bay), Alaska approximately 400 m from Xeitl Sit’ (LeConte Glacier). Data were collected from October 9, 2016 to May 10, 2017. Raw data files from the recorder are compressed .DSG files, which require the included DSGread.m MATLAB file to convert to acoustic pressure. Recordings are also included in WAV format, which may be read by any audio processing software. Ambient noise levels, defined as the 25th-percentile-level, may be computed for individual DSG files using the included AmbientNoiseLevelComputation.m script. Acoustic data may be compared with additional data sets captured of the environment during this time, including meteorological data from Amundson, et al. (2017) (https://doi.org/10.18739/A2K86G) and motion of icebergs using time-lapse photography from Amundson, et al. (2017) (https://doi.org/10.18739/A2J38KJ1W).### 数据获取权限 所有.wav及.DSG格式的声学数据文件均可通过以下目录链接访问并下载：[http://arcticdata.io/data/10.18739/A2VD6P67P](http://arcticdata.io/data/10.18739/A2VD6P67P)。 ### 数据集概览 本数据集包含来自自主水听器（autonomous hydrophone，Loggerhead Instruments DSG-ST）的被动水下声学录音数据，该设备锚定在阿拉斯加Xeitl Geeyi（勒孔特湾）水深120米处，距离Xeitl Sit’（勒孔特冰川）约400米。数据采集于2016年10月9日至2017年5月10日期间。 记录仪产出的原始数据文件为压缩.DSG格式，需使用随附的DSGread.m MATLAB脚本将其转换为声压数据。录音数据同时提供WAV格式，可通过任意音频处理软件读取。可通过随附的AmbientNoiseLevelComputation.m脚本对单个.DSG文件计算环境噪声级（定义为25%分位声压级）。 声学数据可与同期采集的其他环境数据集开展对比分析，包括Amundson等人（2017）发布的气象数据（https://doi.org/10.18739/A2K86G），以及Amundson等人（2017）通过延时摄影获取的冰山运动数据（https://doi.org/10.18739/A2J38KJ1W）。
