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...

TimpeallachtThe term bathymetry refers to the ocean's depth relative to sea level, it can also be used to describe submarine topography or underwater terrain. INFOMAR bathymetry data is measured primarily by multibeam (MBES) and also singlebeam(SBES) echosounder devices. MBES transducers...

TimpeallachtINFOMAR backscatter data is measured primarily by multibeam (MBES) and also singlebeam(SBES) echosounder devices. MBES transducers transmit multiple a high frequency pulses of sound from beneath a vessel in a fan shape down to the seabed. The amount of energy reflected back...

This is a 5 m resolution bathymetry tif in WGS84 projection. The survey was carried out on the R.V. Keary using a hull mounted EM3002 multibeam echosounder. Data was subsequently processed using CARIS HIPS and SIPS software. Depths in the survey area ranged from 0m to 55m, all...

This inter-institutional survey took place in May 2011, as part of a Geological Survey of Ireland-led ground-truthing programme. The Marine Institute's R.V. Celtic Explorer collected sea bed samples from an East-West transect along the top of the high. Vibrocores, grab samples...

TimpeallachtA side scan sonar is used when high resolution information on specific seabed features is required (e.g. habitat mapping or wreck investigations). The unit is towed behind the vessel in close proximity to the seabed and transmits high frequency sound pulses that map the seabed...
