Here we see Antarctica (Google Earth view) and a cut to show the interior of the earth, where the mantle (red and dark red) and the core (yellow) are visible. The Amundsen Sea Embayment (ASE) is indicated by the red rectangle.
Note that the largest arrow represents 4.1 cm/yr. Then we can see the photos of four the GPS sites, clockwise from top left: Bear Peninsula (BERP) (Photo Credit: Bill MaGee), Backer Islands (BACK) (Photo credit David Saddler), Inman Nunatak (INMN) (Photo Credit: Jeremy Miner), Lepley Nunatak (LPLY) (Photo Credit: Jeremy Miner). In the center we can see a zoom over ASE with the measured uplift velocities (black arrows) at the GPS sites. From the left to the right the station codes are LPLY, THUR, INMN, BACK, TOMO, BERP. Each photo of GPS site portrays the small mushroom-shaped GPS antenna and the nearby much larger equipment with solar panels. The solar panels are almost vertical because the sun in Antarctica is always very low on the horizon. More on GPS on www.polenet.org
