Development of technologies for low-cost oceanographic unmanned aeronautical vehicles

open access: yes, 2009
Oceanographic research vessels and buoys typically provide high-resolution, shortrange measurements at a high sample rate. Satellites provide wide-range, low-resolution measurements at a low sample rate. Therefore a gap exists in oceanographic observation capability for medium-range, high-resolution measurements at a high sample rate.
