Researchers developed the first transcriptomic database for mahi-mahi embryos and larvae exposed to oil from the Deepwater Horizon incident. The team assembled over 60,000 transcripts, identified over 30,000 gene sequences, and observed 2,345 genes that differed significantly after exposure to weathered oil.
A Louisiana State University researcher conducted laboratory experiments to learn how estuarine fish behave around sediments containing varying concentrations of weathered and fresh oil. He observed that fish exhibited a stronger avoidance response to medium and high concentrations of fresh oil compared to low concentrations and observed no significant avoidance of any weathered oil concentrations.
Scientists ran model simulations for oil evaporation based on composition measurements of fresh Macondo crude oil and weathered surface oil from Deepwater Horizon slicks.
Study on mahi-mahi embryos and larvae shows toxic oil affects developing heart, eye and neurological function
A large team of scientists used a combination of complex, cutting-edge-science testing methods to expand the understanding of the chemical components present in weathered oil.
