Harbour porpoise detection and buzz positive minutes before and after the rerouting of a major shipping lane in Kattegatt (TANGO)

Passive acoustic data stretching from a year before to a year after the relocation of a major shipping lane in Kattegat (2020-07-01). 15 stations were distributed in four transects (NW, SW, NE, SE) near (1–5) the original or relocated shipping lane. Data was collected with a C-POD and processed in CPOD.exe with the KERNO filter at an 8 cycle threshold (www.chelonia.co.uk). Detection minutes and train details was exported and compiled into minute time series with detection and buzz (train minimum inter-click interval <10) positive minutes. The files consists of time series data at 1 minute resolution. First column TIMESTAMP (yyyy-mm-dd HH:MM) and three Boolean (0/1) columns for: if the instrument was on or not (ON); if the minute was detection positive (DPM); if the minute was buzz positive (BPM). The file header also includes station name, position, approximate depth and data coverage. All data gaps are filled with the missing TIMESTAMP and instrument not (0) ON. This data is used in the study “No change in overall presence and habitat use of harbour porpoises (Phocoena phocoena) by rerouting of a major shipping lane in Kattegat (Baltic Sea)”.

Stations in Swedish waters was managed by Department of Environmental Research and Monitoring, Swedish Museum of Natural History. Data processing was done by the museum.

本数据集为卡特加特海峡（Kattegat）某主要航道改道前后各一年的被动声学监测数据，航道改道发生于2020年7月1日。15个监测站沿西北、西南、东北、东南四条断面布设，分布于原航道或改道后航道1至5公里范围内。数据由C-POD被动声学监测仪（C-POD）采集，经CPOD.exe软件搭配KERNO滤波器（KERNO filter）以8次循环阈值完成处理，数据处理方法来源为www.chelonia.co.uk。研究人员导出检测阳性分钟数与声脉冲列细节，并整合为分钟级时间序列，其中包含检测阳性分钟与脉冲丛（声脉冲列最小点击间隔<10）阳性分钟。

数据集为分钟分辨率的时间序列文件：首列为时间戳（TIMESTAMP，格式为yyyy-mm-dd HH:MM），另有三列布尔型（0/1）变量，分别标记仪器开机状态（ON）、该分钟是否为检测阳性（DPM）、该分钟是否为脉冲丛阳性（BPM）。文件头信息包含监测站名称、布设位置、近似水深及数据覆盖范围。所有数据缺失时段均补全缺失的时间戳，并标记仪器处于未开机（0）状态。

本数据集用于发表于《卡特加特海峡（波罗的海）主要航道改道对港湾鼠海豚（Phocoena phocoena）整体出现率与栖息地利用无影响》的研究，欲获取更多研究详情，请参阅该已发表论文。

丹麦海域的监测站由奥胡斯大学生态科学系海洋哺乳动物研究组负责运维；瑞典海域的监测站由瑞典自然历史博物馆环境研究与监测部负责运维，数据处理工作由该博物馆完成。
