  1. DWH Science Summit LSU Science in Support of DWH Oil Spill Minerals Management Services June 3, 2010

  2. Immediate Science Actions (since incident)  MMS is providing scientific experts and technical direction in the development and participation in Response Teams and the Unified Command for DWH oil spill with multiple agencies.  MMS is providing extensive data and model results for the prediction of the spilled oil to aid response and clean up planning and response.  Collection of reports and data from MMS Gulf of Mexico Studies for baseline assessment and extensions of ongoing projects • Lophelia II Project with NOAA – 2008-2009 Deep Water Corals for baseline data. • Deep water circulation and Loop Current Studies

  3. Immediate Science Actions (since incident)  Oceanographic Models and Measurements  MMS participated in an interagency oil spill model review team to ensure the highest confidence in the results.  Dispersant Studies  MMS provided information and references from funded TAR and ESP studies including two NRC books.  Passive tracer modeling at the surface and 800 m depth; conducted sub-surface sampling to detect the fate and concentration of DWH oil and dispersants  Magnitude of the DWH Spill  MMS is participating in the Flow Rate Technical Group (FRTG) which will provide scientifically validated information to determine the volume of DWH oil flow and spill.

  4. MMS - NOAA/AOML Airborne Survey of Loop Current using airdrop probes  MMS - NOAA/AOML ongoing airborne surveys of Loop Current (LC) for use in oceanographic models and hurricane study. http://www.aoml.noaa.gov/  MMS provided an additional $100K for spill response and deployed 180 AXBT and 60 AXCTD since DWH spill. Deployment of bathythermographs

  5. MMS - NOAA/AMOL Airborne Survey Flight Patterns over Loop Current  Recent survey (5/21) reveal that LC may be in the process of shedding Loop Current Eddy (LCE); surveys will continue. SSH Image from University of Miami

  6. Near-Term Science Actions (1-6 months)  Modification of MMS ongoing contracts to target DWH spill issues have been initiated  Socio-economic Studies  MMS/LSU conference (5/26-28, 2010) in Gulf of Mexico Region to discuss baseline socio-economic data and planning for study design  Dispersant Studies (providing technical direction)  Exposure studies to better understand the impacts if dispersants on biota

  7. Near-Term Science Actions (1-6 months)  MMS Loop Current Study (contract with SAIC)  Extensive mooring arrays have been deployed in the center of the LC to investigate its dynamics; first year data will be available for hindcast modeling  Water samples will be collected and analyzed at the mooring sites during the rotation to track the extend of DWH spilled oil

  8. Near-Term Science Actions (1-6 months)  Ongoing interagency MMS/NOAA OER/USGS study (NOPP) of deep-water coral habitats (Lophelia II) identified as invaluable source of pre- post-spill data  Existing photomosaic images acquired at sites near and distant to DWH oil spill location  Currently operating sediment/larval traps near and distant to DWH oil spill location  MMS/NOAA OER/USGS Lophelia II study contractor has been identified for NRDA proposal on deep coral habitats to include rapid response field sampling cruise

Near-Term Science Actions (1-6 months) Study sites for ongoing MMS/NOAA OER/USGS Lophelia II project Lophelia deep-water coral Photomosaic of deep-water coral Madrepora Operating time-series sediment Block GC 852, 4,625 ft depth. traps, one located directly under DWH oil spill and one located outside: both at deep coral sites

  10. MMS Environmental Studies Program Gulf of Mexico Projects  LSU Coastal Marine Institute Partnership  Effects of Loop Current and Loop Current Eddies - Analysis Using the Real-time MMS ADCPs from Oil Platforms  Multiple Deep Water Studies concluding through 2010. MMS contractors – SAIC, LSU, TAMU, CICESE, Evan- Hamilton, Inc, Princeton University  Climatological, Bio-Physical and Deep water Models in development with multiple partners and contractors.

  12. Long-Term Science Actions (2 mos. to decades) MMS Studies Plan Development  Coastal and At-Sea Gulf Coast Spill Impacts  Impacts of the DWH spill on sea turtles  Impacts of the DWH spill on productivity, nutrient cycling and species composition of Gulf Coast marshes  Long-term Monitoring  Hydrocarbon monitoring studies at the surface and in the deep sea communities  Residual effects of dispersants and dispersed oil in the environment and target species

  13. Long-Term Science Actions (2 mos. to decades)  Contract modification to existing MMS/NOAA OER/USGS Lophelia II project to address DWH spill impacts  Additional field sampling 2010 and adding 2011  NOAA OER expected additional contribution of ROV in 2011  Continued improvements of ocean models and oil spill trajectory methods  AMAPPS – Marine mammal, sea turtle and sea bird mapping program, utilizing historic and new data for species mapping expanded to Gulf since DWH spill.

  14. Long-Term Science Actions (2 mos. to decades) PARTNERSHIPS Research, Coordination, Information & Dissemination*  MMS/LSU Coastal Marine Institute  NOAA, USGS, Navy  IOOS, GCOOS, SECOORA  National Ocean Partnership Program  Cooperative Ecosystem Study Units *MMS uses Cooperative Agreements and Contracts to facilitate the timely delivery of information.
