Small Autonomous Aircraft for Economical Oceanographic Observations on a Wide Scale
Economical Oceanographic Observations Wide Scale
2015/8/19
A prototype aerosonde, which will fit comfortably on a desktop, and can be packed in two boxes sufficiently small to be taken as airline luggage, is shown in Figure 1. It will have a range of over 7,0...
Spatially adaptive sampling is necessary to resolve evolving gradients with sparsely distributed sensors. Assessing the reality of numerical model fields with ever increasing resolution, testing dynam...
Observing the Ocean with Autonomous and Lagrangian Platforms and Sensors:The Role of ALPS in Sustained Ocean Observing Systems
Autonomous Lagrangian Platforms Sensors ALPS Sustained Ocean Observing Systems
2015/7/31
Oceanographers have long dreamed of a detailed, 4-D view of the ocean. The last decade has witnessed a revolution in autonomous ocean observing capabilities as new platforms and sensors developed, and...
Mid-Ocean Ridge Exploration with an Autonomous Underwater Vehicle
Autonomous Underwater Vehicle Ocean
2015/7/22
Human-occupied submersibles, towed vehicles, and tethered remotely operated vehicles (ROVs) have traditionally been used to study the deep seafloor. In recent years, however, autonomous underwater veh...
