Long-Term Monitoring Data of Offshore Wind Farms in the Belgian Part of the North Sea (2005-2023)

This dataset presents findings from environmental impact assessments conducted from 2005 to 2023 in different OWFs of the BPNS. Samples were collected by means of Van Veen grab of 0.1m². Some samples belonging to the monitoring of one turbine (D5) in C-Power were collected by divers a differents distances (1, 7, 15, 25, 50, 100, 200 m) from the scour protection layer in 2010, 2011 and 2012. Subsamples of each Van Veen were taken for grain size analysis, and total organic matter content analysis. The remaining part of the Van Veen were sieved over a 1 mm sieve on board and stored in a 4% formaldehyde-seawater solution. In the laboratory, the samples were stained with 1% Rose Bengal, and rinsed over a 1 mm sieve. The organisms were counted and identified to the lowest possible taxonomic level (generally: species level) and stored in a 4% buffered formaldehyde solution.

本数据集呈现了2005年至2023年间，在比利时北海海域（Belgian Part of the North Sea, BPNS）内不同海上风电场（Offshore Wind Farms, OWFs）开展的环境影响评估结果。样品采集采用面积为0.1平方米的范·维恩采泥器（Van Veen grab）。另有部分用于C-Power风电场内单台机组（D5）监测的样品，由潜水员于2010、2011及2012年，在距冲刷防护层不同距离（1、7、15、25、50、100、200米）处采集。每份范·维恩采泥器采集的样品均取子样，用于粒度分析与总有机质含量测定；剩余样品在船上通过1毫米孔径筛网筛分后，保存于4%甲醛-海水混合溶液中。实验室阶段，样品经1%孟加拉玫瑰红（Rose Bengal）染色后，再次通过1毫米孔径筛网冲洗；随后对采集到的生物进行计数，并鉴定至尽可能低的分类学层级（通常为物种水平），最后保存于4%缓冲甲醛溶液中。
