Oil spill research from the sea and air

3689561201?profile=originalThe University of Miami is studying oil spills with drifters, UAVs, and a kite!  From The Atlantic:

More than three-and-half years after the Deepwater Horizon disaster spewed millions of gallons of petroleum into the Gulf of Mexico, scientists are launching drones and ocean-going sensor arrays off the Florida coast in an effort to map the path of future oil spills before they devastate beaches and coastal ecosystems.

Researchers from the University of Miami and other scientists are placing 200 GPS-equipped “drifters” in the surf zone just off Fort Walton to map where the ocean currents take the devices. Sensors placed on the ocean surface and seabed will track the movement of colored dye that will be released during the three-week experiment that began today. Two drones outfitted with GoPro cameras will also monitor where the currents take the drifters and dye. Since the drones can only stay aloft for an hour at a time, a camera-carrying kite will also be deployed.

All the data collected will be used to construct a computer model of near-shore ocean currents to predict how future oil spills or other pollutants will disperse as the approach the shore.

“Computer models will be able to give us better estimates of where the oil spill will go, and how fast and in which patterns it will spread,” Tamay Özgökmen, a University of Miami professor and the director of the Consortium for Advanced Research on Transport of Hydrocarbons in the Environment, told The Atlantic in an email. “This can help emergency responders to better direct their limited resources. In the longer term, models are also helpful to make sense of any ecological damage that may have occurred in the environment.”

For instance, that model can also predict where currents will carry shrimp larvae – crucial information given the importance of fishing to the Gulf Coast economy.

The Surfzone Coastal Oil Pathways Experiment is part of a larger $500 million effort funded in part by oil giant BP in the wake of the Deepwater Horizon catastrophe. Depending on the strength of the currents, the drifters and drones will be deployed over an area that could stretch from hundreds of square yards to many square miles, according to Özgökmen.

And a link to the official PR from the UM Rosenstiel School of Marine & Atmospheric Science:

MIAMI – (Dec. 2, 2013) – A University of Miami (UM) Rosenstiel School of Marine and Atmsopheric Science-led study to understand the path of oil or other pollutants in coastal areas begins offshore of Ft. Walton Beach, Florida today. During the three-week SCOPE Experiment – Surfzone Coastal Oil Pathways Experiment – scientists will deploy GPS-equipped drifters and other advanced instruments to study the ocean currents along the coast to better understand how oil may move onshore in the event of a future spill.

“In the aftermath of the Deepwater Horizon oil spill it became clear that understanding the ocean currents in the surfzone is vital to improve our understanding and prediction of oil spills,” said Dr. Tamay Özgökmen, UM Professor and Director of the Consortium for Advanced Research on Transport of Hydrocarbons in the Environment (CARTHE). “There are catastrophic socio-economic impacts when oil spills reach our beaches.”

UM Professor Ad Reniers and his colleague Professor Jamie MacMahan from the Naval Postgraduate School in Monterey, Calif., will deploy a variety of instruments, including 200 GPS-equipped drifters, unmanned aerial vehicles and pressure and dye sensors at the surface and at varying depths, to measure the movement of ocean currents along the coast to study how oil, fish larvae, or toxins in the water are carried by currents close to shore.

“This study will collect important data necessary to understand the ocean currents in the near-shore marine environment,” said Reniers, associate professor of applied marine physics at the UM Rosenstiel School and lead investigator of the SCOPE Experiment. “The information collected will be used to develop computer models of the coastal zone, to improve our scientific understanding of this region in the event of a future oil spills, as well as to better understand how larvae or water pollutants travel close to shore.”

The unmanned aerial vehicles will be equipped with cameras to monitor the drifters and used in a dye experiment, where EPA-approved colored dye is placed in the near-shore waters to collect visual data on the movement of currents. Several of the drifters being deployed during the experiment were designed by students from three Florida high schools, MAST Academy, South Broward High School and Maclay School, as part of a CARTHE-sponsored educational outreach program. This research is made possible by a grant from the Gulf of Mexico Research Initiative (GoMRI). The GoMRI is a 10-year, $500 million independent research program established by an agreement between BP and the Gulf of Mexico Alliance to study the effects of the Deepwater Horizon incident and the potential associated impact of this and similar incidents on the environment and public health.

SCOPE is the second large experiment conducted by CARTHE that brings together a wide range of scientific experts and experiment with measurement methods to study oil spills. The first experiment, called GLAD (Grand Lagrangian Deployment), was conducted near the Deepwater Horizon site in the summer of 2012 also under the support of GoMRI. Information collected by scientists from both experiments will be used to model the transport and fate of oil in the Gulf of Mexico, in the event of a future spill.

The SCOPE Experiment is a project of the UM-based CARTHE. The CARTHE program includes 26 principal investigators from 12 research institutions in eight states. Together these scientists are engaged in novel research through the development of a suite of integrated models and state-of-the-art computations that bridge the scale gap between existing models and natural processes.

    Not the only folks heading down this path, just yesterday I was sent this....

    http://www.suasnews.com/2013/12/26251/support-for-oil-spill-response/

    The International Association of Oil and Gas Producers (www.ogp.org.uk) in conjunction with the International Petroleum Industry Environmental Conservation Association (www.ipieca.org) have commissioned an Oil Spill Response (OSR) Joint Industry Project (JIP). One of the JIP objectives is to review commercial satellite and airborne remote sensing capabilities relevant to Oil Spill Response and to identify gaps in this provision.

    You are kindly invited therefore to complete a survey giving relevant information on your respective platforms and/or sensors applicable to OSR to help support this endeavour. This will lead to a resource of information on relevant suppliers for the oil and gas industry, and will help provide recommendations for the future application of airborne remote sensing in OSR.

  • Interesting article!  Thanks for sharing this Brandon!
