Accurate position data show that Brunt Ice Shelf has an irregular three-dimensional motion driven by the ocean tide. A 30-day GPS record from Halley station shows not only the expected vertical tidal displacement, but also a significant variation in horizontal velocity. The maximum forward velocity...
