A borehole is any hole drilled or dug into the ground. The hole is usually deep, narrow and round. The material (soil and or rock) from the hole is collected and tested in a laboratory to find out the structure and type of the soil and or rock beneath the ground. A borehole...

ScienceGroundwater is the water that soaks into the ground from rain and can be stored beneath the ground. Groundwater floods occur when the water stored beneath the ground rises above the land surface. The Groundwater Flooding Medium Probability map shows the expected flood extent...

Karst is a type of landscape where the bedrock has dissolved and created features such as caves, enclosed depressions (sinkholes), disappearing streams, springs and turloughs (seasonal lakes). Limestone is the most common type of soluble rock. As rain falls it picks up carbon...

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....

The term Physiography can be described as a blending of “physical" and "geography". Physiographic Units show Ireland’s physical landscape divided into categories such as ‘Bedrock plain’ and ‘Flat to undulating sediments’. Areas are grouped based on bedrock geology (solid rock...

Minerals are naturally occurring; they are not made by humans. They are inorganic in that they have never been alive and are not made up from plants or animals. They are solid, not liquids (like water), or gases (like the air around you). Each one is made of a particular mix...

These maps shows the aggregate potential across Ireland. To produce these maps, scores were given to each area based on several factors such as rock type suitability, number of quarries, area, elevation etc. The final score was a number between 5 and 100 The maps shows the...

The Quarry Directory shows the location of sand and gravel, crushed rock and dimension stone quarries in Ireland. A questionnaire was sent to all known active quarries and pits (around 1,700). A location map (Ordnance Survey Ireland (OSI) 1:50,000 Discovery Series) was...

This map shows the areas where sub-bottom profile data is available in Irish waters. Sub-bottom profile data shows the rock features and the sediment layers that are below the seabed. A sub-bottom profile is created by sending sound waves from the vessel to the seabed. The...

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 Ireland would be made up of if these materials were removed. As the bedrock is commonly...

Research ships working at sea map the seafloor. The ships collect bathymetry data. Bathymetry is the measurement of how deep the sea is. Bathymetry is the study of the shape and features of the seabed. The name comes from Greek words meaning "deep" and “measure". Backscatter...
