Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Sub-bottom profile data shows the rock features and the sediment layers that are below the seabed. </SPAN></P><P><SPAN>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><P><SPAN>The Sub-bottom profile polygons show the area of the vessel has collected Sub- bottom profile data. The attributes in these polygons will instruct you how to download the Sub-bottom data.</SPAN></P></DIV></DIV></DIV>
