Data about physics, biogeochemistry and paleoceanography of the eastern subtropical North Atlantic.

These grid data were derived from National Parks and Wildlife Service cetacean surveys within the Irish MSFD area and the EEA-10km GRID. The grid shows the current distribution of Harbour seal (Phoca vitulina) in Irish coastal and marine waters. The data were collected for the purposes of 2019 reporting under Article 17 of the EU Habitats Directive.

These grid data were derived from National Parks and Wildlife Service cetacean surveys within the Irish MSFD area and the EEA-10km GRID. The grid shows the current distribution of Harbour seal (Phoca vitulina) and Grey seal (Halichoreus grypus) in Irish coastal and marine waters. The data were collected for the purposes of 2019 reporting under Article 17 of the EU Habitats Directive.

This spatial dataset indicates the depth of fishing activity within the inshore area around the Irish coastline. Data was created via surveys with fishermen around the coastline.

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).

The Irish Groundfish Surveys is part of an annual International Bottom Trawl Survey (IBTS) programme co-ordinated by the International Council for the Exploration of the Sea (ICES). The survey is carried out over 47 days between October-December each year by the Marine Institute and collects demersal trawl and ancillary data in Irish waters to produce relative abundance indices for fisheries management in the Northwest Atlantic Shelf waters.

Acoustic surveys are generally carried out on spawning and pre-spawning aggregations of fish.

The survey is intended to collect information on maturity, sex ratio, growth, etc. for a number of species that are of commercial importance. The survey takes place in early spring, the time when most fish spawn. It is important to sample during the spawning season as immature fish can be easily distinguished from mature fish during this time.
