Scientists conducted laboratory experiments to investigate if copepod behavior can reshape the size frequency distribution of oil droplets. They observed that copepods directly changed it through the combined movement of their feeding and swimming appendages and by ingesting oil droplets and discharging undigested, smaller-sized oil drops. The animals’ actions created feeding
Scientists developed a platform at environmentally-relevant scales to advance the study of oil-water interface interactions, biofilm formation, and particle dispersion. Their techniques allow one to control the size, shape, and volume of oil micro-drops and then affix them onto a stable substrate where microbes can live and grow. The technology provides an unprecedented capability in investigating complex interactions of bacteria, cells, and interfaces and to study key microbial processes involved in remediation of environmental pollutants,
The Gulf of Mexico Research Initiative (GoMRI) congratulates Dr. Joseph Katz on his election to the National Academy of Engineering 2019 class, one of the highest professional distinctions accorded to an engineer. A formal induction ceremony for the new class will be held during the academy’s annual meeting in October in Washington, D.C.
Several thousands of years ago, when the pharaohs ruled ancient Egypt, organic matter in the oceans like seagrass and by products of fish waste created during their time is just now breaking down and transferred back into the atmosphere.
Dissolved organic matter is one of the most stable sources of carbon there is and it can take several thousands of years to breakdown. Chemists at The University of Texas Marine Science Institute recently made a ground-breaking discovery about the shape and structure of this ancient type of carbon. In a
Oil is a complex mixture of chemicals with different degradation behaviors and toxicity levels. Understanding how the compounds in spilled oil, particularly toxic compounds, change with weathering is important to predicting oil’s persistence in the environment. Meredith Evans Seeleyanalyzed how oil compounds are preserved or removed over time in coastal systems that have different hydrographic activity levels. Her research will help

Harmful algal blooms, or red tides, can occur naturally, but new research indicates that after an oil spill, the application of dispersant may increase the chance of red tides. A new paper recently released in Environmental Science and Technologyprovides experimental evidence that oil and dispersant applications may open up a hole in the food web that toxic bloom-forming algae take the opportunity to fill.
When an oil spill occurs, they can disproportionally kill the single-
The University of Texas at Austin ranked No. 11 among all U.S. institutions (academic and nonacademic) and No. 10 among U.S. universities for publication of scientific research, according to the latest report from the Nature Index.
Impressive high school senior joins DROPPS lab to analyze bacterial compositions in the Gulf with sophisticated new equipment
By Lalitha Asirvadam
High school senior Helen Schawe from Veterans Memorial High School in Corpus Christi, TX, is working on some exciting new research in Dr. Jian Sheng’s lab at Texas A&M University-Corpus Christi. Dr. Sheng is a Co-Principal Investigator in the Dispersion Research on Oil: Physics and Plankton Studies (DROPPS) consortia within the Gulf of Mexico Research Initiative. DROPPS is
Laser light and high-speed cameras can help researchers observe the behavior of oil droplets within a laboratory-simulated oil plume and interpret how the oil subsequently may move through the water column.
