2 Logistics Fire Exits Restrooms Lunches and snacks today and tomorrow Poster Session at lunch and tonight (Cash Bar) Dinner tonight (on your own) Logistical questions see Meredith Field or me 3 Coastal Response Research Center (NOAA Funded) UNH Oil Spill Centers Since 2003 Center for Spills in the Environment (All Other Funding) Conduct and Oversee Basic and Applied Research and Outreach on Spill Response and Restoration Serve as Hub for Oil Spill R&D (ALL Stakeholders) Facilitate Collaboration on R&D Among Stakeholders 4 2
3 Facilitation Encourage everyone to speak Discourage side conversations Commit to: Being engaged in meeting Texting and discouraged Keeping on task and time Being faithful to process 5 Goal of Meeting Obtain comprehensive view of factors controlling formation, flocculation, deposition, and accumulation of oilassociated marine snow on seafloor During oil and gas release and dispersant application Integrate ongoing studies Develop new ideas and collaborations 6 3
4 Overall Goals Define processes/frameworks Understand spatial and temporal variations of each process Delineate manifestation in sedimentary record Determine impacts (biological and chemical) on processes and ecosystems Feed information on processes, sediments and impacts into numerical models to predict ecosystem response to spills. 7 Overall Goals Processes Sediments Impacts LONG TERM GOAL Numerical Models Prediction of Ecosystem Response 8 4

9 GOOD MORNING!!!! October 22 23, 2013 Agenda Revise Conceptual Model and Examine Data Putting It All Together 18 9
10 Breakout Group II Questions Breakout Group II Revise Conceptual Diagram and Examine the Data What data exist regarding different aspects of your conceptual diagram? What data are being collected? What data need to be generated by new projects? What are the research projects needed to obtain these data? 19 Breakout Group III Questions Breakout Group III The Big Picture What synthesis products are needed to develop a holistic picture of what happened to Marine Snow during the Deepwater Horizon? How do these products help compare what happened to Marine Snow to historical conditions (non spill)? How will these products help improve future oil spill response? 20 10
11 21 Agenda 22 11
12 Breakout Group Questions Breakout Group III What syntheses are needed to develop a holistic picture of what happened with respect to Marine Snow during the Deepwater Horizon Incident? How do these products help compare what happened to Marine Snow during the Deepwater Horizon event to historical conditions (non spill)? How will these products help improve future oil spill response actions (e.g., timing of release of Mississippi River flows into the Gulf of Mexico)? 23 Group 1: Oil Associated Marine Snow Location: Room 120 Presenter: Ali Khelifa Facilitator: Kendra Daly Rapporteur: George Jackson Vernon Asper Eric Chassignet Meredith Jennings Vijay John InOk Jun Sara Kleindienst David Lindo Ian MacDonald Olivia Mason Tinka Murk Tamay Özgökmen Elizabeth Simons Evan Variano 24 12
