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.

What do the students get out of this?
1)Experience Multimodal Multiplatform Science2)Numerous speaking opportunities – Learn to Communicate.3)Research on their Resume.4)Leads to Summer Internships – National & International.5)Leads to Graduate School Acceptances.6)Leads to Job Offers from Glider Operations Centers.7)Leads to higher rankings in the environmental job market.8)Meet national and international leaders in oceanography.9)Develop friendships that persist across space and time.10)They return to tell others of the importance of this experience.

OOI: EPE Glider Tools
Focus: Building tools for educators to use in the introductory undergraduate classroom
Fisheries & Habitats
Ecological Decision Support – Fisheries
Our Approach: Develop statistical models using bottom trawl surveys and MARACOOS 3-D data to predict species distribution based on observed or forecasted MARACOOS 3-D fields.

Receiver Integrated Glider• Mobile tracking of offshore
environments • Reach currently
unmonitored areas• Natural addition to
ongoing research• Increase understanding of
fisheries interactions• Enables coupling of data
sets – Telemetry data– Temperature– Salinity– Productivity
• Moves us beyond fixed arrays

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
