Wandering Poles on Europa
A new study in the May 15th issue of Nature from NAI’s Carnegie Institution of Washington Team reveals that Europa’s poles may not have always been located in the same place. Using images from three NASA spacecraft, Voyager, Galileo, and New Horizons, the study mapped surface features on Europa and matched them with a pattern predicted if Europa had experienced an episode of ~80 degree true polar wander. This movement of the pole and subsequent change in rotation axis is only possible if Europa’s outer shell is decoupled...

Taking the Ocean's Pulse
Near the town of Moss Landing, California, midway between Santa Cruz to the north and Monterey to the south, the Salinas River empties lazily out into the Pacific Ocean. What makes this otherwise unremarkable juncture unique is that it lies at the mouth of Monterey Canyon, one of the longest and deepest underwater canyons in continental North America. Virtually unknown, and largely unexplored, the sheer size of Monterey Canyon puts it squarely in league with its celebrated upcountry counterpart, the Grand Canyon. Which explains why not one but two major marine research centers – Moss Landing Marine Laboratories and Monterey...
