Sub-bottom profile data shows the rock features and the sediment layers that are below the seabed.<\/SPAN><\/P>

A sub bottom profile is created by sending sound waves from the vessel to the seabed. The length of time it takes for these sound wave to return from the seabed to the vessel is measured. The length of time tells us how hard the material below the seabed is. Hard material such as solid rock returns the sound wave very quickly. Soft material such as mud returns the sound wave very slowly. <\/SPAN><\/P>

The Sub-bottom profile polylines show the route of the vessel as it collected Sub- bottom profile data. We refer to these polylines as tracklines.The attributes in these tracklines also include the name of the Sub-bottom file that produced it. The attributes also include hyperlinks to download the raw Sub-bottom profile data.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "mapName": "IE_GSI_Sub_Bottom_Profile_Tracklines_Inshore_IE_WGS84_LAT", "description": "
