Traditional ocean research techniques are widely augmented today with in situ sampling packages on moorings, buoys, floats, flow-through systems, mobile platforms (gliders, AUVs, and ROVs), integrated sensor networks, and observatories. These are vibrant research and development areas and generate the most accurate data available, 3D, often in real-time, and are less affected by adverse conditions. However, spot sampling lacks the rapid, broad coverage that is critical in high-level real-time tactical decision making. In situ observations at times are not available for unsafe or denied-access environments. Remote sensing techniques (both active and passive) have been proven to offer synoptic surface coverage with adequate accuracy, when sensors are calibrated and validated correctly. It is essential to establish and maintain precise protocols for deciding the appropriate mix and application of different sensor systems in order to maintain data coherence and comparability. Further, modern defense and security needs demand that accurate information be provided when and where it is needed (e.g., Battlespace on Demand). Ocean sensing must provide not only timely and accurate data but also offer insights regarding overall 3D and future environmental conditions, i.e. forecasting. The combined use of in situ observations, remotely sensed data, and physical models is a rapidly evolving field to be effective, although improved assimilation of available data into models still poses a challenge. The ability to sense, integrate, and predict is vital in establishing a true real-time 4D cube of verified and validated information for ocean nowcast and forecast.
This conference is aimed at bringing together research and technical personnel, from industry, governments, and especially academia, to foster cooperation to increase the utility of operational oceanographic assets to meet defense and homeland security concerns.
