Wave glider robots await launch from San Francisco in this first expedition blog post in Google Earth.
From the Google Earth blog:
Join a journey of discovery virtually in Google Earth, as Liquid Robotics launches four wave-powered robotic gliders to cross the Pacific ocean in their Pacific Crossing (PacX) Challenge Expedition. The wave gliders are attempting to set a new world record for the longest distance ever attempted by an unmanned vehicle and will be collecting data about the Pacific ocean for use by scientists and students back on dry land. These R2D2s of the sea will cross 25,000 miles over 300 days and collect over 2 million data points, helping build the record of oceanic knowledge.
To follow the wave gliders in Google Earth, download the expedition KML file or open the PacX Gallery page and click on the ship icon. You will be able to read updates from scientists sharing the latest robotic observations, from wave height in storms to weather measurements like barometric pressure, wind speed and air temperature. The ship icon will represent the location of the wave gliders, starting in the San Francisco bay.
