The Zugspitze Geodynamic Observatory Germany (ZUGOG) has been setup on the summit of mountain Zugspitze at an altitude of almost 3000 m during 2018 with the main scientific objective being a better understanding of seasonal and long-term mass redistributions in the European Alps. This knowledge is very important (e.g. with regard to water storage and its high sensitivity to climate change), but is ...[Read More]

We know the topography of the moon better than the Earth’s seafloor, so we need to keep studying the ocean, and, for me, going to sea is the best way. Only twenty percent of the seafloor is already mapped (see the Seabed 2030 Project), leaving eighty percent of our ocean unmapped, unobserved, and unexplored. This is why ocean going research is fundamental, not only for seabed mapping, ...[Read More]
