ONLINE COVER Adaptive Robotic Sampling. The coastal waters near Runde Island, Norway, are affected by strong winds, ocean currents, and freshwater runoff from land. Fossum et al. used a light autonomous underwater vehicle (LAUV) to survey the edges of predefined volumes, and the resulting data allowed the robot to identify interior areas with high concentrations of subsurface chlorophyll a for additional, detailed sampling. LAUV results were confirmed with data from remote sensing and shipboard samples. The combination of real-time data analysis and accurate, adaptive robotic sampling may improve our understanding of marine food webs and their dynamic, heterogeneous environments.
