Steve Chien, 2024, "Sensorweb Systems for Global High-Resolution Monitoring of Environmental Phenomena", https://doi.org/10.48577/jpl.AGWI0O, Journal of Aerospace Information Systems, JPL Open Repository
Many science phenomena are difficult to observe because they occur infrequently and without warning. Over the course of the last twenty years, the concept of a "sensorweb", or a network of interdependent instruments that autonomously coordinate to observe phenomena of interest, h... |

Mattia Poinelli, 2024, "Can rifts alter ocean dynamics beneath ice shelves?", https://doi.org/10.48577/jpl.QM6MHD, The Cryosphere, JPL Open Repository
Land ice discharge from the Antarctic continent into the ocean is restrained by ice shelves, floating extensions of grounded ice that buttress the glacier freshwater outflow. The ongoing thinning of these ice shelves - largely due to enhanced melting at their base in response to... |
