Autonomous Ocean Sampling Network-II (AOSN-II): Integration and Demonstration of Observation and Modeling

摘要

The AOSN-II project explored the ability of large-scale ocean observing systems to characterize and predict ocean state. The creation of an extended coastal observatory was identified as a realizable first step. The project developed key components and assembled them into an adaptive coupled observation/modeling prediction system. Two major field programs were carried out. Technical effort addressed optimization of observation system performance, creation of data systems for supporting distributed operations managed by geographically distributed experts, and mobile autonomous platform technology. To optimize observation system design, we developed methodologies for selecting ocean observing locations and sampling strategies for objectives such as estimation of scalar fields, currents, budgets, and fluxes. Our data system development for the AOSN-II and MB2006 field programs, created software components which made data easy to access and multidisciplinary data sets easy to search. We also created collaborative portal approaches which allowed investigators to function as an integrated team for field operations despite being located on opposite sides of the continent. Finally, insights from analysis of the field programs informed development of a new long-range autonomous underwater vehicle, the Tethys.
