The impact of fishing on benthic habitats has previously been investigated however; a conclusive classification of potentially sensitive habitats per gear type does not exist. Currently only qualitative estimates of fishery impact using Broad-scale habitat maps are possible. Here a sensitivity matrix using both fishing pressure (fishing Intensity) and habitat sensitivity is employed to define habitat disturbance categories. The predominant fishing activities associated with physical abrasion of the seafloor area are from bottom contacting towed fishing gear. The swept area of the aforementioned gear in contact with the seabed is generally considered a function of gear width, vessel speed and fishing effort (ICES. 2015). The varying characteristics of fishing gear, their interaction with the sea floor and species being targeted; provide scope for differing interactions with subsurface (infaunal) and surface (epifaunal) dwelling communities. An evaluation of the abrasion pressure and habitat sensitivity split into surface and subsurface pressure allows greater insight to the ecological effects. Fishing intensity was calculated annually and based on the area of sea floor being swept (or swept area ratio SAR) by gear type. Calculations are based on SAR’s of gear types per area, per year. Fishing pressure ranks and habitat sensitivity ranks obtained from WGSFD working group (01 WGSFD - Report of the Working Group on Spatial Fisheries Data 2015) can be incorporated within a GIS environment to existing ICES fisheries data to provide habitat disturbance maps (fishing pressure maps+ habitat sensitivity maps) ICES. 2015.

Catch numbers per species from Irish Groundfish Survey haul stations. The Irish Groundfish Survey covers fisheries trawl stations in the North Atlantic Ocean, Celtic Sea, Irish Sea and Saint Georges Channel around Ireland. The Irish Groundfish Survey has been a two-legged survey taking place each October-December since 2003. Irish Groundfish Survey involved shot and haul stations at regular sites where fish species are caught and processed on board the Irish research vessel RV Celtic Explorer in the fisheries lab. The primary goal of the Irish Groundfish Survey has been to develop estimates of juvenile abundance for important fish species. Measurements of the abundance of juvenile fish are a critical measure of the health of a stock, serving as an annual indication of recruitment (the number of newly spawned fish which enter the population each year) success or failure. Most importantly, they allow forecasting of future commercial abundance. In addition, the Irish Groundfish Survey provides data on the distribution and biology of commercial and non-commercial species of ecological interest, as well as hydrographic and environmental observations. When these data are combined with annual recruitment indices they have helped identify the possible causes driving year-class success or failure, and allowed fisheries scientists to see long-term changes in populations that may have been caused by fishing, pollution, or climate change. The Irish Groundfish Survey feeds into the International Bottom Trawl Survey (IBTS) for international reporting. The Irish Groundfish Survey has been managed by the Fisheries Ecosystem Advisory Services (FEAS) section of the Marine Institute (Ireland). Data complete for each year survey has taken place.

Boarfish surveys have been carried out on commercial fishing vessels as part of an industry/science partnership. Boarfish surveys have taken place in the Celtic Seas around Ireland including the North Atlantic Ocean. They have taken place each July and have been collected since 2011. Outside of the spawning season many pelagic species were generally very scattered over a large geographical area and difficult to detect using acoustic methods. A cruise track was first formulated with data from previous surveys, commercial catch data and the help of the fishermen and fishing industry. Acoustic surveys for boarfish have been generally carried out on spawning and pre-spawning aggregations of boarfish to ascertain the abundance and distribution of the target species. Boarfish are the newest species surveyed by Fisheries Ecosystem Advisory Services of the Marine Institute (Ireland). Data is 100% complete for the survey years since 2011.

Estimated annual average wave period (seconds) created by a Pelamis Wave Model for Accessible Wave Energy Resource Atlas. Wave period values are measured as lower and upper values in seconds as calculated by the Pelamis wave model. Annual average wave period covers an area known as the Irish Exclusive Economic Zone (EEZ). Data model produced in 2005. The Pelamis Wave Model was an oceanographic model using the Pelamis wave energy converter device. The Accessible Wave Energy Resource Atlas produced to provide data and information on the accessible wave energy resource potential around Ireland. Wave model developed by ESB International (ESBI) as part of the Accessible Wave Energy Atlas Ireland published by the Marine Institute and Sustainable Energy Authority Ireland. Model completed for time period run.

The Atlas of Commercial Fisheries around Ireland reviews the fishing activity on fish stocks of relevance to Ireland that come under the EU Common Fisheries Policy (CFP). The Atlas focuses on fishing opportunities (Total Allowable Catches – TACs), landings trends, fleet activity and the state of the resource in the waters around Ireland (principally ICES Sub-areas VI and VII). The Atlas also deals with fish stocks exploited by Ireland outside Sub-areas VI and VII. Every effort has been made to use the most up to date information available on fishing opportunities, landings, effort, and on the state of the resource base. The various ICES and STECF reports and databases together with various EU Regulations should be consulted for the definitive figures and regulatory articles. The Atlas was completed during 2009. The Atlas focus was on fisheries Data Collection, Data Management, Data Analysis, Conducting Assessments, Formulating and Providing Advice and Carrying out Scientific Research on Fish Stocks, both Nationally and Internationally. The Atlas focused on stock assessment to support European fisheries policy. Atlas completed by Marine Institute fisheries science teams. Data in atlas complete per publication date.

The dataset indicates the location for bottom trawl fishing activity in Irish waters. Attributes when known include year, area, gear type, species, season, days per year (Days_Year), number of vessels (Vessels), vessel size (LOA_Max), gear units, classification, Area of polygon (Area_M2), and data type. This dataset was created in support of the Natura 2000 risk assessment in 2013. Please note that this dataset represents bottom trawl activity for vessels <15 metres length in Irish waters.

The Accessible Wave Energy Resource Atlas published in 2005 describes an initial comparison between several years of hourly wave forecasts (using WAM) on a grid of points located off the Irish coast with corresponding records from a number of buoys installed in recent years. Based on the level of agreement found the wave forecasts were then modified slightly and used to estimate the mean annual practicable power resource around Ireland.
