First, you need to have Google Earth installed on your computer, tablet, or phone, or you can use the online version.
Second, you need to download the KML file with the ice buoy tracks onto the same device. The KML file you need for that can be found here directly.
Third, you need to know how to import the KML file into Google Earth. Google Earth Help has a nice description for how to import KML files into Google Earth on different devices. You can find it here!
By following those three steps, you will be able to see the tracks of our ice buoys in Google Earth!
