This map shows the distribution of seabed substrate classes within Irish waters. High resolution grids of MBES bathymetry and backscatter data have been interpreted into 5 substrate classes: Rock, Coarse sediment, Mixed sediment, Sand and Mud to muddy Sand classes. Backscatter is

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 recor

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

Groundwater is the water stored below ground in tiny cracks in the rock or in very small spaces between sand grains. It comes from rainwater that soaks into the ground into an aquifer. An aquifer is a body of rock and/or sediment that holds groundwater. The process of rain fillin

Water tracing involves tagging water to see where it goes. The time the tracers take to get from one point to the other is also usually recorded. It is most commonly used in karst environments to ascertain groundwater flow rates, directions and catchment definitions (Zone of Con

Different aquifers have differing abilities to store and transmit water. Based on the hydrogeological characteristics and on the value of the groundwater resource, GSI has classified Ireland’s land surface into aquifer categories. GSI Aquifer classes are divided into three main

This Hydrostratigraphic Rock Unit Groups map is a reclassification of the 1:100,000 bedrock geology map, created by grouping bedrock formations and members into 27 Rock Unit Group categories based on their hydrogeological properties and other factors.

Karst is a landscape with distinctive landforms that develop on rock types that are readily dissolved by water. In Ireland, karstification mostly occurs in limestone regions.
This karst dataset contains mapped karst landforms in Ireland including: boreholes, caves, dry valleys, e

The groundwater vulnerability concept is based largely on the question “can water and contaminants move in the subsurface materials (soil and subsoil) and/get down to groundwater easily?”
Groundwater is most at risk where the subsoils are absent or thin and in areas of karstic li
