Irish Benthos monitoring as part of the Water framework directive since 2012

A requirement of the Water Framework Directive is that benthic macro-invertebrates must be sampled from coastal and transitional waters at least twice within a river basin cycle (6 years) in order to classify these waterbodies. Numerous samples will be taken from sites in matched habitats throughout the water body. Sampling and analysis is carried out according to established protocols. The Directive requires the sampling of nominated coastal and transitional waters for benthic macro-invertebrates. This includes the field sampling, processing and analysis of samples. In addition, grab samples have been taken on vessels of opportunity and are considered suitable to fulfill obligations under the WFD. For each grab sample collected this dataset contains: - lists and abundance of benthic species >1mm, -sediment particle size analysis (PSA), -Folk (1954) sediment classification, and an estimate of organic matter (LOI).

《水框架指令》的一项要求是，为对沿海水域和过渡水域进行分类，必须在一个流域周期（6年）内至少对这些水域中的底栖大型无脊椎动物进行两次采样。将在整个水体范围内的匹配栖息地站点采集大量样本，采样与分析遵循既定规程开展。该指令要求对指定沿海水域和过渡水域的底栖大型无脊椎动物进行采样，涵盖现场采样、样本处理及分析环节。此外，利用机会船采集了抓斗样本，这些样本被认为足以履行《水框架指令》（WFD）规定的义务。对于每个采集的抓斗样本，本数据集包含以下内容：- 大于1mm的底栖物种名录及丰度；- 沉积物粒度分析（PSA）；- Folk（1954）沉积物分类；- 有机质估算值（LOI）。
