"Our newest addition to the shipwreck project is a map showing some of the better known shipwrecks. This map has four overlays, which you can turn on and off by clicking on the small icon in the top left corner (they are off as a default). The first is main shipwreck map (red dots) showing wrecks that are close to the New Jersey coast. The second overlay is the offshore wrecks (purple stars). The third overlay is all of the wrecks sunk as part of the NJ Artificial Reef project (green circles). The final overlay is the original location of all the New Jersey US Life Saving Stations (blue diamonds). Each overlay can be removed to give a better view of ships from a different overlay. Please note that all ship locations are approximations. This map is not intended as an aid to navigation or treasure hunting."
