On the shelf, Friday

There was a blog choke last night, looks like I erased my message. Anyway, lets recap where we are.

Gliders, they are flying really well.  We have broken the ru21 to north to study the interesting features we saw in the mid-shelf.  The University of Delaware's glider was deployed and is heading offshore (we are having an icon issue, should be fixed when John K. today, the glider is the "X").  The other two gliders Ru5 and RU 23 continue in on the shore.  As they reach the shallower waters, chlorophyll values continue to rise. Offshore waters show colder water temperatures and the salinity is is higher in the nearshore waters.  Nice validation for the winter bloom, more below. The glider to the north is seeing similar features despite being in deeper water.  A reminder vertical data for people's interest can be found at http://marine.rutgers.edu/cool/auvs/?page=deployments.






What do the current show?

The currents have been calming down, and explains the great progress being made by the gliders.  The path planner is very fun, and we tip the morning coffee to our JPL partners.  The currents are likely to increase in the day as it is projected to whip up.  Good thing the AUV team got their work in yesterday.  The forcatsed currents are predicted to whip mostly offshore, and the inner shelf still is predicted to be calm.  Below is the ROMS forecast from the Rutgers group. The ensemble model is also below with the variance in the  U and V components.   The errors in the ensemble model have decreased with variance being on the order of 5 cm/s on in the inner shelf in the U component, 10-15 cm/s in the V component.
