Crude oil contains tens of thousands of hydrocarbons, including polycyclic aromatic hydrocarbons (PAHs) that create unique chemical fingerprints for different types of oil. Dawei “David” Shi uses geochemical analysis techniques in mesocosm studies to track these fingerprints, observe how they change over time, and investigate how dispersant affects PAH concentrations in the water column. David Read More

Grad Student Morales-McDevitt Explores How Nutrients Influence Marine Snow Formation Maya presents her preliminary findings at the 2016 Gulf of Mexico Oil Spill and Ecosystem Science Conference. (Provided by Maya Morales-McDevitt)

Marine oil snow is the largest commuter of carbon to the seafloor and occurs when oil and marine particles aggregate and sink through the water column. Previous studies show that oil and dispersant significantly increased marine microorganisms’ production of exopolymeric substances (EPS), an extremely sticky goo that holds marine snow together. Maya Morales-McDevitt conducts mesocosm experiments investigating how certain Read More

Meet ADDOMEx Undergraduate Students Cameron and Oscar! Undergrads at work

Cameron Jackson, a sophomore, is studying marine biology Texas A&M University at Galveston (TAMUG) and Oscar Agueda is a senior who will be getting his degree in marine science (TAMUG); both students are minoring in chemistry. When asked about career aspirations they stated that they hoped to go on to graduate school. “I want to Read More

ADDOMEx Researcher Helps Introduce Teachers to Engineering James_Chiu_1579

James Chiu presented the ADDOMEx Consortium’s research to nearly seventy teachers participating in a program called Team-E Science, which will help them better understand engineering concepts. The program is part of a three-year endeavor to implement engineering curriculum in Merced and Mariposa county schools. Underrepresented minority groups make up more than half of the student body Read More

Smithsonian’s Five Questions with Biological Oceanographer Uta Passow Uta Passow hopes to better understand the movement of carbon in the Gulf of Mexico. (Photo Credit: ECOGIG)

Phytoplankton are active organic carbon producers and help drive the processes that move carbon from the ocean surface to the sea floor. Scientists are investigating impacts from the sudden large input of carbon from the Deepwater Horizon spill on this important biological cycle. The Smithsonian Ocean Portal recently featured Uta Passow with the University of Read More
