A borehole is any hole drilled or dug into the ground. 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 record or log is a written description of the mat

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 at

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 cover

Landslide locations and extents help us locate where landslides have occurred. Ireland's location, terrain and climate result in landslides occurring mainly in areas with steep slopes where rock meets the surface and peat covers the terrain. Landslides have the potential to cause

A landslide is the movement of material down a slope. This includes rock, earth, mud and peat. Landslides in Ireland mainly occur on steep mountain slopes.
A landslide susceptibility map shows areas where a landslide could occur, how likely it will occur and what causes them. The -

The Dublin Soil Urban Geochemistry Project is a baseline survey of heavy metals and organic chemicals in topsoils in the greater Dublin area. Topsoil is the upper surface layer of the soil and this geochemical baseline survey measures the amount and type of chemicals in these su

The 1:500k bedrock maps provide a simplified, smaller scale view of the bedrock geology of Ireland. The map was created in 2013 using the detailed 1:100k geology linework and polygons, which was adjusted and scaled to provide the best representation of the geology at this overvie

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 length

Groundwater is the water that soaks into the ground from rain and is stored beneath the ground. An aquifer is a body of rock and/or sediment that holds groundwater. The process of rain filling up an aquifer is called ‘recharge’.
The Groundwater Recharge map shows the amount of ra

This data shows the depth of the seabed around Ireland. The data was collected in 1996 and between 2000 and 2022.
Bathymetry is the measurement of how deep is the sea. Bathymetry is the study of the shape and features of the seabed. The name comes from Greek words meaning "deep"

The Scheme Reports Groundwater Protection map provides links to county based reports.
A groundwater protection scheme has land surface zone map(s) and groundwater protection responses for potentially polluting activities e.g., landfill, land spreading and septic tanks.

This Backscatter map shows how hard or soft the seabed is in Irish waters. The seabed in Ireland’s inshore area is between 0 and 200 metres deep. The data was collected from 2001 to 2022. The seabed in Ireland’s offshore area is between 200 and 5000 metres deep. The data was coll

Soil is the outside layer of Earth. It is a made up of living organisms, gases, minerals, and organic matter. Knowing what elements are in the soil helps to work out where it came from and how it was made.

Geological heritage or ‘geoheritage’is the term used to describe sites or places with features of geology that have important scientific, educational, cultural, or visual value. There are many types of sites. They are made from past and present geological processes (wearing away
