Agenda
Ship IOP ops overview/discussion
Modeling update from GA Tech.
Asset position reporting (MTS)
Ship IOP ops
– 4 vessels (Sally Ride, Sproul, Oceanus) + small vessels
OSU small boat timing plans: 8-18 Sept, 9-16 Oct
– surveys in space for fluxes, onshore propagation of internal SW
only 4-5 days with all vessels (12-16 Sept)
maximize number of sampling vessels for the phenomenon in question (multiple synoptic gradients)
coordinating aircraft and drifter deployments
synoptic surveys near mooring arrays 10-70m depth
use model to analyze actual survey patterns
large scale survey in evenings (boundary conditions for modeling, microstructure)
Oct, only 2 vessels
– Ship Plan expected in about 1 month
– headland areas
– recognize south, landbased radar coverage
– drifter integration?

Modeling
– ongoing forward modeling, from 3km down to 22m North grid almost completed (all available except for 22m grid coupled to wave model on the scrips modeling blog, check there)
– Discussing experimental forecast for the fall field work, question to the group: how useful given computational expense?
Generally seen as very useful, 66m N, 200m grid would be adequate for ops planning
200 m L3 grid would be very useful for use on the UNOLS vessels, cross-shelf density gradient
How accurate? Will verify 2009 runs with data to assess, Ata has some collected data for validation
– Inverse modeling for flow field stability analysis
– Diagnosing adjoint sensitivity analysis
