The Accessible Wave Energy Resource Atlas 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. The report contains 31 figures, 43 tables and 127 graphs and was based on the analysis of approximately 51 million individual forecast and recorded values of significant wave height and wave period. The Accessible Wave Energy Resource Atlas dataset contains 24 GIS polygon files including calculations of annual average wave height and period, seasonal/annual mean technical power resource (MW), seasonal/annual mean theoretical wave energy resource (MW per hour), seasonal average power flux (kW) from Pelamis wave energy device and seasonal/annual mean technical energy (GW per hour). The data was collected within the boundary of the Irish Exclusive Economic Zone including the North Atlantic Ocean, Irish Sea, Saint Georges Channel and Celtic Sea. The report and atlas data was published in December 2005. Using Pelamis, a floating wave power converter developed by Ocean Power Delivery Ltd. in Scotland, available in 2005, allowed the mapping of the mean seasonal and annual wave energy potential around Ireland. The atlas was produced with a view to documenting the differing levels of resource that exist around the coast as an aid to policy planning and development and in line with its objective of marine resource development and wealth creation. The Accessible Wave Energy Resource Atlas was commissioned from ESB International (ESBI) by the Marine Institute (MI) in late 2004 with support from Sustainable Energy Authority Ireland (SEAI) and produced in December 2005. The data generated was considered a complete representation of results produced by the wave model.

Licensing rounds awarded by the Petroleum Affairs Division (PAD) in the Irish Atlantic Margin. The 2015 licensing round includes three regions. The Irish Atlantic Margin geographic coverage includes foreshore and offshore waters in what is known as the Currently Designated Irish Continental Shelf. Licensing awarded in 2015. PAD awarded licences to oil and gas exploration companies via licensing options upon application. The role in the Petroleum Affairs Division is to maximise the benefits to the State from exploration for and production (E%amp;P) of indigenous oil and gas resources. In doing this PAD ensure that activities are conducted with due regard to their impact on the environment and other land/sea users through appropriate licensing.

The Full Scale Atlantic Marine Energy Test Site (AMETS) provides 30 minute observational data from two directional waverider buoys known as Belmullet A and Belmullet B observing and measuring wave height, wave direction and wave period. The AMETS buoys are located in the North Atlantic Ocean in waters off the coast of the Erris Peninsula in Co. Mayo at 50m and 100m bathymetry depths. AMETS has been collecting data since 2012. A directional Waverider is a wave motion sensor stabilised platform that can measure the properties of waves including height, direction and period. The AMETS programme has been jointly managed by the Marine Institute and the Sustainable Energy Authority of Ireland. Data coverage 100% for when the buoys have been operational. Any data gaps in time period indicate the buoy(s) have been non-operational and have been under maintenance.

Designated wave energy test site for supporting ocean energy device research and development at 1/4 scale. The Galway Bay 1/4 scale wave energy test site is located 1.5km from Spiddal pier within inner Galway Bay on the west coast of Ireland. Data has been collected in Galway Bay since 2008. Data is collected from current meter sensors, wave device sensors and water temperature sensors. Data has been collected to support ocean energy research technological innovation and development. Data has been collected by the Marine Institute in association with SmartBay Ireland. Data has been incomplete given periods of outage of wave energy sensors. Data has been complete and quality controlled for period devices are observing and measuring in the marine environment.

Estimated annual average wave height (metres) created by a Pelamis Wave Model for Accessible Wave Energy Resource Atlas. Wave height values are measured as lower and upper values in metres as calculated by the Pelamis wave model. Annual average wave height 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 was 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.

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 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.

Mean average *offshore* wind speeds in metres per second (m/s) at 50m above sea level. The wind speed data, modelled in 2003, covers the Irish Internal Waters and the Irish Territorial Sea up to 12 nautical miles from the baseline. The Sustainable Energy Authority of Ireland (SEAI) offers the same data in its Wind Atlas, a digital map of Ireland's wind energy resource (http://gis.seai.ie/wind). SEAI's wind speed datasets assist wind energy planners, developers and policy makers. __Background on 2003 wind maps__ The 2003 wind-mapping project was completed by ESB International and TrueWind Solutions for SEAI (then SEI). It predicted wind characteristics, at heights of 50m, 75m and 100m, spanning onshore and offshore. (Larger heights of 125m and 150m were later covered in SEAI’s 2013 wind-mapping project.) The resulting GIS maps cover onshore in 200m grids, and offshore in 400m grids. Generally, wind maps extend to 15km offshore, or occasionally 20km. About the 2003 methodology, it iterated a MesoMap system and a faster WindMap model through reducing grid sizes. MesoMap is built on MASS (Mesoscale Atmospheric Simulation System), a numerical weather model that embodied the fundamental physics of the atmosphere. Iterations through the nested grids accounted for local land elevation, land cover and roughness. Final iterations accounted for increased wind shear and reduced near-surface wind speed at less windy sites. The 2003 Wind-mapping Project Report is available [here](https://seaiopendata.blob.core.windows.net/wind/Report_2003_Wind_Atlas.pdf).
