DWH Science Summit LSU

Science in Support of DWH Oil Spill

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

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.

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.

MMS provided an additional $100K for spill response and deployed 180 AXBT and 60 AXCTD since DWH spill.Deployment of bathythermographs

Recent survey (5/21) reveal that LC may be in the process of shedding Loop Current Eddy (LCE); surveys will continue.

Near-Term Science Actions(1-6 months)

Modification of MMS ongoing contracts to target DWH spill issues have been initiated

Socio-economic StudiesMMS/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

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

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 locationCurrently 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
