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...

A well is a hole dug into the ground usually for the purpose of taking water from the ground but also for monitoring groundwater. Most private wells are used for home and farm water supplies are in rural areas. Springs occur where groundwater comes out at the surface. A...

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....

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...

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...

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...

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...

Marine sediment is considered any deposit of insoluble material, primarily rock and soil particles, transported from land areas to the ocean by wind, ice, and rivers, as well as the remains of marine organisms, products of submarine volcanism, chemical precipitates from...

The Regional Ocean Modeling System (ROMS) is a free-surface, terrain-following, primitive equations ocean model widely used by the scientific community for a diverse range of applications. The operational Northeast Atlantic (NEATL) model is an implementation of the ROMS model...

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...

Location of marine basin divisions in the North Atlantic around Ireland. A geological basin is a large low-lying area. It is often below sea level. There are five designated basins and each basin represents a large submarine depression of a generally circular, elliptical or...

The IMAGIN study has concluded that a number of areas with potential to support marine aggregate extraction exist within the Irish Sea and that marine aggregates can contribute to the sustainable management of demand and future use of aggregates in Ireland.

Data on the offshore volcanic geologic ridges near Ireland in the West European Basin. A ridge is a geological feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance. Ridges are usually termed hills or mountains as well,...

Data on the offshore geologic igneous features in the North Atlantic Ocean near Ireland. Igneous rock (derived from the Latin word ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling...
