Plans going forward into tomorrow and the weekend

Today was an exciting day during the OSSE.  We had friendly debate and lots of great ideas.  This is what the future of oceanography can be, and I feel very lucky to be part of it. We also had give the strategy to the JPL path planner to provide the gliders the next set of waypoints.

The crux of the debate was where do we send the gliders? The AUV? Where should we send the U. Deleware glider? What should be the glider configuration for the saturday Hyperion satellite pass? What science do we want to address?

Several in the group wanted to get gliders to the north to resolve some interesting transport issues.  See Yi's thoughts in the earlier blog.  Others wanted to head the gliders in nearshore to confirm the presence of the winter bloom?  Others wanted to fan out in the mid-shelf in parallel lines to validate models?  Discussion of the way forward continued in discussion in many of the groups late into the afternoon.  Given uncertainities that need to be resolved about shipping lanes, to figure out where are the safe northern zones, the inital decision to give the JPL scientists time to run the path planner, a decision was to fan out the gliders as they head in back to the mid shelf.  Tomorrow we will figure out the distribution to cover uncertainity in the north and anchor the shelf wide modeling efforts. The gliders are making good progress. They are now heading onshore, this path planning is cool!


In the afternoon, discussion continued for over an hour with Julia Leven, Scott Glenn, Wendell Brown, Oscar Schofield, and Javier Zavaka-Garay. Currently the path planner uses the ensemble model  to guide the path planner.  One issue is that we know all the models have different uncertainities and errors.  We focused our discussion on the variability in the currents as this is what influences the ability of the gliders to fly. Below is ensemble currents, below that are variance in the u and v components between the models.  Our discussion focused on using the gliders to minimize the variance (decrease the red areas),  and how that might be a path forward for how we prioritize missions in the next two weeks.  The cross shore lines tonight should help minimize the uncertianity in the mid shelf where the winter bloom is occuring, and then we plan how to resolve the northern area that is of interest to a bunch of the OSSE science team.  What a great day to be an oceanographer!
