2010_PHD_REUBENS - Acoustic telemetry data for Atlantic cod (Gadus morhua) in the C-Power wind farm in the southern North Sea (Belgium)

This is an acoustic telemetry dataset published by Ghent University. It contains animal (fish) tracking data collected by what later became the Permanent Belgian Acoustic Receiver Network <a href=\"https://lifewatch.be/en/fish-acoustic-receiver-network\"> (https://lifewatch.be/en/fish-acoustic-receiver-network)</a> for the project/study 2010_phd_Reubens, using VEMCO tags (V9) and receivers (VR2W). In total 41 individuals of Atlantic cod (<i>Gadus morhua</i>) were captured, tagged and released in 2010 and 2011 in the C-Power wind farm in the Belgian part of the North Sea, to study their movement behaviour and assess the impacts of offshore wind farms on their movement ecology. This dataset also includes the data of the synchronisation tags present in the study. To calculate exact 2D positions using acoustic telemetry, the time difference of arrival of signals at different receivers is used. Therefore sync tags are needed to account for clock drift in the receivers.
Intensive exploitation of the marine environment by mankind can alter the natural habitat of marine organisms drastically. The addition of artificial hard substrates (e.g. offshore wind turbines) to soft-sediment sandy bottoms is a pervasive example of an anthropogenic habitat change. In this study, we assess the influence of offshore wind farms on the spatio-temporal movement ecology of Atlantic cod (<i>Gadus morhua</i>). The results of this study will be useful for management measures for the conservation and restoration of the cod population.

Data have been standardized to Darwin Core using the <a href=\"https://inbo.github.io/etn/\">etn</a> package and are downsampled to the first detection per hour. The original data are managed in the European Tracking Network data platform (<a href=\"https://lifewatch.be/etn/\">https://lifewatch.be/etn/</a>) and are available in Reubens et al. (2020, <a href=\"https://doi.org/10.14284/437\">https://doi.org/10.14284/437</a>).

本数据集为根特大学发布的声学遥测数据集（acoustic telemetry dataset）。其包含2010_phd_Reubens项目/研究中，由后发展为比利时永久声学接收器网络（Permanent Belgian Acoustic Receiver Network，链接：https://lifewatch.be/en/fish-acoustic-receiver-network）的机构采集的动物（鱼类）追踪数据，数据采集使用了VEMCO标签（V9）与接收器（VR2W）。2010至2011年间，研究人员在北海比利时海域的C-Power风电场共捕获、标记并放归41尾大西洋鳕鱼（<i>Gadus morhua</i>），旨在研究其移动行为并评估海上风电场对其移动生态学的影响。本数据集还包含研究中使用的同步标签（synchronisation tags）数据。利用声学遥测计算精确二维位置时，需使用信号到达不同接收器的时间差；因此，同步标签可用于校正接收器的时钟漂移。

人类对海洋环境的密集开发会显著改变海洋生物的自然栖息地。在软质沉积物沙质海底添加人工硬质基底（如海上风力涡轮机）是人为栖息地改变的普遍案例。本研究旨在评估海上风电场对大西洋鳕鱼（<i>Gadus morhua</i>）时空移动生态学的影响，其结果将为鳕鱼种群保护与恢复的管理措施提供参考。
