Service Description: This map shows the ship survey lines where the seabed has been mapped in Irish waters.
The seabed is mapped using boats. The boats use special equipment called a multibeam echosounder. A multibeam echosounder is a type of sonar that is used to map the seabed. Sound waves are emitted in a fan shape beneath the boat. The amount of time it takes for the sound waves to bounce off the bottom of the sea and return to a receiver is used to determine water depth.
The data are collected as points in XYZ format. X and Y coordinates and Z (depth). The boat travels up and down the water in a series of lines (trackline). An XYZ file is created for each line and contains thousands of points. The line files are merged together and converted into gridded data to create a Digital Terrain Model of the seabed. We use different sized boats and equipment depending on the depth of the water. This data shows the extent of each survey area. It also gives information on the boat and equipment used to map the area.
It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).
The tracklines are shown as lines. Each line holds information on the line type,survey id, day, project, time, heading, comments, geographical area, id, trackline km, sound velocity profiles and sub-bottom profiles.
This data shows ship survey lines that have been surveyed. There are plans to fill in the missing areas between 2020 and 2026. The deeper offshore waters were mapped as part of the Irish National Seabed Survey (INSS) between 1999 and 2005. INtegrated Mapping FOr the Sustainable Development of Ireland's MArine Resource (INFOMAR) is mapping the inshore areas. (2006 - 2026).

Subject: Mapping the seabed is vital to understanding many activities at sea. This data shows the ship survey lines where the seabed has been mapped in Irish waters.
Seabed mapping supports shipping and navigation so boats can safely navigate and not crash/scrape off rocks hidden below the water and not get stuck on sand banks. Seabed mapping is vital to managing fishing so nets don’t tear on rocks and fish found in different habitats are protected. Seabed mapping is important in planning such as sites for wind, wave and tidal energy, fish farming and the laying of cables and pipelines. Seabed mapping is required to supporting marine tourism and leisure events involving ships and boats. Seabed mapping supports the discovery of ships wrecked at sea.
