Our Integrated Marine Observation pages use the Microsoft Virtual Earth Mapping interface to display real time readings from sensors and instruments managed us. To use the map, select the icons you want to view - these are located below the map. By selecting tick boxes icons will be displayed on the map. By placing the pointer over an icon information will be displayed in relation to the icon. The Map can be also viewed with Ocean or Contour information. These options can be selected in the Map Overlay menu.
