N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 2/16 ASAP Program Ocean Processes Ocean Model Model Prediction Data Assimilation Adaptive sampling Learn how to deploy, direct and utilize autonomous vehicles (and other mobile sensing platforms) most efficiently to sample the ocean, assimilate the data into numerical models in real or near-real time, and predict future conditions with minimal error.

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 3/16 Goals of ASAP Program 1.Demonstrate ability to provide adaptive sampling and evaluate benefits of adaptive sampling. Includes responding to a. changes in ocean dynamics b. model uncertainty/sensitivity c. changes in operations (e.g., a glider comes out of water) d. unanticipated challenges to sampling as desired (e.g., very strong currents) 2.Coordinate multiple assets to optimize sampling at the physical scales of interest. 3.Understand dynamics of 3D upwelling centers a.Focus on transitions, e.g., onset of upwelling, relaxation. b.Close the heat budget for a control volume with an eye on understanding the mixed layer dynamics in the upwelling center. c.Locate the temperature and salinity fronts and predict acoustic propagation.

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 4/16 Approach 1.Research that integrates components and develops interfaces. 2.Focus on automation and efficient computational aids to decision making. 3.Virtual pilot study in December 2005? Develop simulator. 4.Field experiment in August 2006.

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 5/16 Glider Plan Guidelines: A.The sampling plans should be designed for data collection that a.Gives data that is understandable (in the oceanographic context) without a model. b.Provides a good map regardless of model. c.Yields good field + parameter estimates when combined with dynamical model. B.Sampling plans should a.Be fully adaptive under operational constraints. b.Change in response to optimization of integration of coverage + sensitivity metrics. C.Gliders operated as cooperative fleet: adaptation of 1 glider implies adaptation of all. Optimal Coordinated Trajectory (OCT). A coordinated sampling pattern for the glider fleet that has been optimized with respect to the above objectives. Coordination. Prescription of the relative location of all gliders (as a function of time).

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 6/16 Glider Plan Feedback to large changes and disturbances. Gross re- planning and re-direction. Adjustment of performance metric. Feedback to switch to new OCT. Adaptation of collective motion pattern/behavior (to optimize metric + satisfy constraints). Feedback to maintain OCT. Feedback at individual level that yields coordinated pattern (stable and robust to flow + other disturbances). Many individual gliders. Other observations. Models and model products

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 7/16 Glider Plan OCT for increased sampling in southwest corner of ASAP box. Candidate default OCT with grid for glider tracks. Adaptation SIO glider WHOI glider

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 8/16 Glider Plan Voting System A web site will be created in which anyone from the team can propose a new area of the ASAP box for special sampling attention (ie propose a rectangle or rectangle from the candidate grid with corresponding time period of interest) and provide a justification for their proposal. There will be a vote on-line. Each group has a vote. Rules for voting TBD. Justification for strong endorsements and rejections of proposals critical. A minimum time interval between consecutive proposals will be imposed. The goal is to implement important adaptation proposals and to be sure to try all the different reasons for adaptation (dynamics, sensitivity, …) over the course of the experiment. Physically possibility will be checked (e.g., can the gliders get to location in timely fashion). Designated person will review all input and make final decision.

Harvard Aug Ocean

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 13/16 Virtual Pilot Study (VPS) -- To be resolved Schedule for VPS? What period of Harvard Aug 2003 ocean should we use? How much of the system plan do we anticipate that we can test in the VPS? Are there developments not yet reflected in system plan that we need to add? Are there critical pieces not getting attention? Who will do these? Where do we need additional effort in integration of methodologies? Where are the interfaces not yet complete? How might preliminary results of OSSE’s help us hone our plan? What remains to do to make data flow? What are remaining open questions that we should consider as a team?

N.E. Leonard – ASAP Planning Meeting - Oct. 6-7, 2005 Slide 14/16 Goals of Meeting Discuss and resolve issues and questions for VPS. Address new ideas and developments for VPS. Finalize VPS plans. Assign remaining action items to be completed in advance of VPS. Determine action items to be initiated in parallel with VPS. Discuss and resolve issues related to ASAP ’06 logistics. Discuss and resolve issues related to larger MB ‘06 multi-project integration (Curtin).
