News: GoMRI Renews CARTHE

2014/11/15 – GoMRI
Gulf of Mexico Research Initiative Awards $140 Million to Support Research

gomri

The Gulf of Mexico Research Initiative (GoMRI) has selected 12 research consortia to conduct scientific studies of the impacts of oil, dispersed oil, and dispersant on the Gulf of Mexico ecosystem and public health. These research investments focus on improving our fundamental understanding of the implications of events such as the Macondo well blowout, and on developing improved spill mitigation, oil and gas detection, characterization and remediation technologies. The consortia were chosen following a competitive, merit review process that evaluated research applications submitted to GoMRI in response to its RFP-IV program solicitation.

Through the RFP-IV program, GoMRI is awarding $140 million to support research to be carried out from 2015 through 2017.

UM Rosenstiel School Scientists Receive Over $29 Million to Study Effects of Crude Oil Spills

Under the leadership of UM Rosenstiel School Professor Tamay Özgökmen, the CARTHE research consortium received over $20 million to continue the research necessary to predict the fate of oil released into the environment to help inform and guide response teams in the event of future oil spills. This second phase of CARTHE, which supports research through 2017, will help scientists develop and improve computational tools to accurately predict the fate of hydrocarbons found in crude oil that are released into the environment, and help to guide risk management and response efforts in mitigation and restoration of the economy and the ecosystem in situations like the Deepwater Horizon oil spill.

“An integral part of any informed response to a future event like the 2010 Deepwater Horizon oil spill requires knowledge of the distribution of pollutants in the water column and the ability to predict where and how fast the pollutants will spread,” said Özgökmen, lead investigator of CARTHE. “This information is also crucial to estimate the pollutants, impact on the local ecosystem and coastal communities.”

Picture This: Developing Storm Surge Visualization

ncsg

When a tropical storm or hurricane develops in the open ocean, the National Hurricane Center, known as NHC, issues advisories that anticipate the track and intensity of the wind field. These advisories predict when and where the hurricane is expected to make landfall, even when the storm is far away from the coast.

This information serves as an input for the ocean model, which then predicts the water levels or storm surges, and wave heights created by these winds at various locations along our coastline for the coming days. These results will convey a greater meaning to the end user when visualized properly. The chief objective for our project is to improve the communication of these model outputs to the end-user by producing them in popular file formats like that of GIS based shapefiles and KMZ files used in Google Earth.

Working with one of North Carolina’s most valuable resources

Dietrich came to NC State with a wealth of experience in coastal modeling, most of it done along the Gulf Coast of the United States. He will soon begin a project with the National Oceanic and Atmospheric Administration to model North Carolina’s coast. Dietrich is part of a research community using a computer model called ADCIRC to predict everything from storm surge and flooding to the feasibility of dredging, or where material floating in the ocean might end up.

When a hurricane is bearing down on the coastline, running the models quickly is of the essence. But the faster the model runs, the less accurate it is. Improving the models so that the time and accuracy trade-off isn’t as sharp is part of Dietrich’s work.

So is figuring out the best ways to visualize the results and get the modeling information to local emergency management officials along the coast so that they can use it.

“It doesn’t help anybody if we are doing this in an empty room somewhere and not sharing the results with the community and sharing them in a way that will maximize their use and maximize their impact,” he said.

Using a high-resolution modeling system, the researchers will expand the utility and accuracy of wave, storm-surge and flooding forecast guidance available to emergency managers in North Carolina. The accurate prediction of these elements is essential for the safety of people and property.

Coastal Engineering Expert Casey Dietrich Joins CCEE Faculty

Dietrich’s work addresses coastal processes, ranging from hurricanes to sediment transport, both of which can transform regions, albeit at rates ranging from hours to many years. Dietrich develops models to describe the oceans in deep water and the nearshore and then validates them against the best available measurements and knowledge of natural behavior. These models lead to improved understanding of the natural and built environments. His models have been used for levee design in New Orleans by the U.S. Army Corps of Engineers and for floodplain risk assessment along the Gulf and Atlantic coasts by the Federal Emergency Management Agency. He has also applied his models to forecast coastal flooding during recent storms including Hurricane Isaac (2012) and oil transport following the BP spill in 2010. He plans to extend his models for civil engineering applications along the North Carolina coastline.

Study Evaluates Accuracy of 2010 Model Predictions for Oil Spill Movement

gomri

During the 2010 oil spill, emergency responders needed forecasts of where oil would go given different scenarios and weather conditions, not just information of current oil location. Forecasts had to account for this first-time situation of oil coming from a deep water source and thus, “the important processes that contribute to oil movement in deep water, on the continental shelf, and within the complex nearshore environment.” Forecasters used the coupled SWAN (Simulating Waves Nearshore) and ADCIRC (Advanced CIRCulation) models to simulate currents that accounted for tides, rivers, winds, and waves. They adjusted their models with data from Lagrangian particle tracking to simulate “short-term (less than 1 week) oil movement.”
