Starting the 2nd week of OSSE

Hi all,

We kick-off the second week of OSSE activities with lots of great accomplishments in the first week, but now look to a final push for the next 7 days. In order to structure the efforts in the coming days, here is an outline of the “events” for the week and the planning of what we want to accomplish with the mobile assets.

We have flown the gliders together to demonstrate the ability to pull assets together. This behavior test complements the tests from the week before where we had 1) gliders fan out away from each other to cover the shelf, 2) gliders fly parallel to each other in cross shore mode, 3) coordinate spatial locations to provide potential cal/val for the Hyperion overflight on Saturday, and 4) demonstrate the ability to swarm by having assets come together. These gliders were complemented nicely with a multiple vehicle deployment last week having several AUVs fly a high resolved box in the nearshore environment. Here not only swarming but vehicle/vehicle communications was tested.

Science efforts have focused on the formation of the winter bloom and initial examination of the unique hydrographic signatures north near the Hudson canyon. There have been nearshore discussions about coastal jets, radiant heating and tides. What has been particularly gratifying is we have been conducting nice behavior test, several very use science data sets have been collected. The question is what is the best use of the assets in the coming week. I toss out candidates that I mined from last weeks dicussions. This first test will be conducted Monday through Wednesday, Wednesday we will have the community choose waypoint missions.

Technology tests:

1) Having the gliders together, choose a mission but have each glider directed by a different model. We have 4 gliders and 5 models + the ensemble. I am still uncertain about how much control we have on the blue hen. Eli can help?

2) Use the variance plots of the ensemble to redirect gliders to areas of maximum uncertainity. Latest plots suggest this offshore, more out in fishing areas, but there are regions on the shelf.

3) There still interesting features on Northern shelf associated with Hudson canyon. Do we fly one or several systems up there? This will be a little challenging given the shipping lanes, but I am open.

Given OOI is supposed to serve the wide range of oceanographers in a distributed manner. I picture the next few days being a test of how a marine IO (me this week) coordinates the activities of science users. You, the modelers are the users. So for today, let’s you guys drive, I will just make sure we fly in safe areas. So think of yourself as the teenager with the keys to the car. I will send our glider status in a few.
