INFOMAR Shipwrecks

Geological Survey Ireland

Timpeallacht

This dataset shows the point locations of shipwrecks in Irish Waters surveyed by INSS and INFOMAR national seabed mapping projects. Over 480 surveyed shipwrecks have been recorded in the INFOMAR shipwreck inventory. The database accurately records the location of shipwrecks (know

INFOMAR Seabed Survey Trackline

Geological Survey Ireland

Timpeallacht

Survey tracklines delineate the line along which the vessel travelled as it was surveying. The vessel collects multibeam echosounder data (MBES) by emitting a fan of soundwaves and recording the reflected signal. The area of seabed ensonified is known as the footprint and the are

Geological Survey Ireland

Timpeallacht

This dataset shows the area of seabed mapped by both the INFOMAR and Irish National Seabed Survey projects to date. Each survey leg is represented by a unique polygon whose title is coded using the initials of the vessel that did the survey, the year the survey was completed and

Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock map shows what the land surface of the North East, Midlands, Cork and Dublin would be made up of if these materials were remove

Before building new structures engineering companies carry out a site investigation to find out the quality of the ground (strength and depth of soil and to see if rock and or groundwater is present). These investigations involve digging holes such as trial pits and boreholes. Th
