A smart sensor web for ocean observation: fixed and mobile platforms, integrated acoustics, satellites and predictive modeling

change research and operational oceanography, there is a need for near real-time integration of data from heterogeneous and spatially distributed sensors, in particular in situ and space-based sensors. The data integration, as provided by a smart sensor web, enables numerous improvements, namely, 1) adaptive sampling for more efficient use of expensive space-based and in situ sensing assets, 2) higher fidelity information gathering from data sources through integration of complementary data sets, and 3) improved sensor calibration. Our ocean-observing smart sensor web pre-sented herein is composed of both mobile and fixed underwater in situ ocean sensing assets and Earth Observing System satellite sen-sors providing larger-scale sensing. An acoustic communications network forms a critical link in the web, facilitating adaptive sam-pling and calibration. We report on the development of various elements of this smart sensor web, including (a) a cable-con
