EnvironmentThis 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...

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...

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...

In terms of time scale in geology, Quaternary is the present-day time and it began 2.6 million years ago. A lot of this time period relates to the Ice Age. Quaternary sediments are the soft material that has been deposited during this time. In Ireland much of this is related...

The INtegrated Mapping FOr the Sustainable Development of Ireland's MArine Resource (INFOMAR) programme is a joint venture between the Geological Survey of Ireland (GSI) and the Marine Institute (MI). The programme is the successor to the Irish National Seabed Survey (INSS)...

Geochemistry of streams sediments can be used to screen for rare minerals and thus help developing local resources. Knowing composition of stream sediments helps to understand what rocks were eroded by the water, where they came from and what resources they might contain....

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...

Streams are important parts of our ecosystem and crucial water sources. Knowing composition of stream waters helps to understand where it came from and how it can be used. Geochemists test stream water samples using different methods to see the spread of elements and ions...
