Study Analyzes Trends and Gaps in Oil Spill Literature Since 1968

April 25, 2017

 

Researchers surveyed oil spill studies between 1968 and 2015 to characterize the field and describe changes. The team found that, despite its episodic nature, oil spill research is a rapidly expanding field with a growth rate greater than science as a whole. Research attention shifted dramatically to the Gulf of Mexico following Deepwater Horizon, rising from 2% of studies in 2004-2008 to 61% in 2014-2015, making Deepwater Horizon the most studied oil spill. The analyses provided insights into research trends and gaps, particularly a long-

DROPPS Hosts South Texas Coastal Zone Area Committee Meeting

February 15, 2017

Yesterday, February 14, 2017, DROPPS hosted the South Texas Coastal Zone Area Committee Meeting at the University of Texas Marine Science Institute in Port Aransas, Texas. These meetings are held quarterly for the response community to update and discuss response plans, case studies of recent spills, overviews of upcoming and past trainings, and more. Yesterday's meeting featured talks from the

Study Develops Predictive Model for Oil-Particle Aggregate Formation

February 6, 2017

 

Scientists developed a new model to predict how much oil from a spill might bind to sediments or organic matter in the water column. The model, A-DROP, introduces a formula that accounts for oil stabilization by particles, particle hydrophobicity, and oil-particle size ratio. The model advances our understanding about the natural removal of oil and contributes knowledge towards development of oil spill mitigation techniques that incorporate oil-particle aggregates. The researchers published their findings in Marine Pollution Bulletin

Responding for Science: UTMSI Scientists Participate in CITGO Oil Spill Response Drill

December 9, 2016

Scientists from the Dispersion Research on Oil: Physics and Plankton Studies (DROPPS) research consortium at The University of Texas Marine Science Institute were on site to observe a recent two-day drill that was organized by the CITGO Corpus Christi Refinery. The drill involved simulating a 55,000 barrel spill of sweet crude oil from the Corpus Christi CITGO refinery which made its way into the shipping channel via Tule Lake. Drs. Hernando Bacosa and Sarah Cosgrove now have intimate knowledge about who to contact and how to participate in sampling

Study Details Underwater Oil Plume Formation and Droplet Size Distribution

August 10, 2016

Scientists simulated an underwater blowout to analyze the formation, path, and duration of oil plumes. They noted that the simulated blowout formed two plumes, one due to momentum and plume buoyancy and another due to the buoyancy of individual oil droplets separating from the first plume.

They also observed that oil plumes form through a two-step process: first, relatively large ligaments of connected oil develop a few inches from the release point in a process called the “primary breakup” and are then entrained back into the plume for their “secondary breakup” into droplets. They

An Oil Spill Science Legacy

An Oil Spill Science Legacy

June 8, 2016

There have been two large scale oil spills over the past 4 decades in the Gulf of Mexico. The Ixtoc I spill in 1979 off the coast of Carmen, Mexico released 3.5 million barrels of crude oil into the Gulf, and the Macondo wellhead blowout off the coast of Louisiana, USA in 2010 released 3.19 million barrels of oil into the Gulf. Both of these incidents resulted in scientists coming together to gather the data needed to understand the fate of the oil, the disturbances it caused to the ecosystem, and its impacts on humans. One of the largest drivers of research efforts surrounding the 2010
