Dutch long term monitoring of macrobenthos in the Dutch Continental Economical Zone of the North Sea

Long term measurements of benthos composition in the Dutch national part of the North Sea. Samples have been taken by benthic sledge, box-corer, video and Hamon sampler. Samples were taken annually between 1991-2010, in 2012 and in 2015 and analysed to the genus or species level. For video sampling, coverage percentages were measured. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive.

本数据集聚焦荷兰管辖北海海域内的底栖生物（benthos）群落组成的长期监测工作。采样采用底栖拖网（benthic sledge）、箱式采泥器（box-corer）、视频采样设备及哈蒙采样器（Hamon sampler）完成。样本采集周期为1991年至2010年每年1次，另于2012年、2015年补充采集，所有样本均鉴定至属或种水平。其中视频采样环节同步测定了生物覆盖百分比。该数据集已被用于东北大西洋海洋环境保护委员会（OSPAR）质量状况报告及《海洋战略框架指令（Marine Strategy Framework Directive）》框架下的海洋环境与栖息地质量评估。
