the establishment of the FRAM (Frontiers in Arctic marine Monitoring) Ocean Observing System improves our monitoring capacities. LTER Observatory HAUSGARTEN Ocean Observing System FRAM [...] Understanding the ocean, and the complex physical, biological, and biogeochemical systems operating within it, is a challenge for the opening decades of the 21st century. The establishment of multidisciplinary [...] multidisciplinary ocean observatories by the Alfred Wegener Institute will help to provide the means to accomplish this goal.
