    The survey existed since 1968. It is carried out every 3 years in the north eastern Atlantic. The year after the Atlantic survey, a mackerel egg survey is conducted in the North Sea. The survey creates a basis for the stock assessment of Atlantic and North Sea mackerel and management plan for Atlantic horse mackerel. The historical MEGS data is expected to be uploaded in 2015-2016. The group responsible for the survey is WGMEGS.

    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).
