Overview of Gliders in Action
Gliders in Modeling(Physics)
Note there are modeling examples throughout talk
Large amount of in situ data allowed tuning of MODAS to better resolve relevant oceanographic features than ever before.
Standard ParametersSatellite data only• Loosely defined Sargasso Sea Front.• Weak, misplaced cold core eddy.• Nonexistent warm core remnant.• Weak current velocities.
Standard ParametersSatellite and in-situ data• Increased detail in Sargasso Sea Front.• Weak, correctly placed cold core eddy.• Weak warm core remnant.• Stronger current velocities.
Tuned Parameters.Satellite and in-situ data.• Undulating detail in Sargasso Sea Front.• Strong, correctly placed cold core eddy.• Turbulent warm core remnant.• Strongest current velocities.

Feedback from the Deepwater Horizon Incident Command
Center
“…Thanks to everyone for all of your efforts to support the Response and the very professional and competent manner in which you have executed your efforts. IOOS has played a huge role in informing the modeling teams and the Unified Command through your extraordinary service. “
- Sam Walker (IOOS representative to Deepwater Horizon Unified Command Center), August 6, 2010
“… AWESOME JOB - that call that we had last week was a very good thing. You are taking a huge burden off of the team here who is trying to simply capture the deluge of assets now being deployed. “
- Sam Walker (IOOS representative to Deepwater Horizon Unified Command Center), July 2, 2010
“All - Greetings from Unified Area Command in New Orleans. I couldn't agree more - the IOOS community has acquitted itself very well during this entire incident. Not only has everyone provided valuable information - you have done it without getting in the way of the ongoing operations. It's been a pleasure to represent IOOS here and see all the great contributions from the larger IOOS community. “
- Sam Walker (IOOS representative to Deepwater Horizon Unified Command Center), June 18, 2010

Westward propagation in glider data and model
• Anomalies in alongshore velocity propagate westward along line 90 offshore of the Santa Rosa Ridge
• Phase speed is consistent with first mode baroclinic Rossby wave
• Propagation not apparent along line 80 in observations, but is strong in model
