Researchers assessed various structures of clay nanotubes or halloysites, which are being studied for their potential in oil spill emulsification. They tested the nanotubes to identify which structures generated the most stable emulsions and smallest oil droplets and if catalytic reactions improved at the oil-water interface.

Researchers used population models to investigate how reduced survival and fertility after environmental disturbances, such as an oil spill, might affect sperm whale populations. Model simulations indicated that the magnitude of a disturbance had a stronger impact on recovery from lethal and sublethal effects than its duration.

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.
Details
Researchers analyzed simulated interactions of oil droplets and marine particle aggregates to understand how they could affect the behavior of an oil spill. The scientists found that the attachment of oil droplets to particle aggregates changed the distribution of oil droplet sizes over time scales of hours.

The Gulf of Mexico Research Initiative congratulates its Research Board Chair Dr. Rita Colwell on her selection as the 33rd laureate of the International Prize for Biology. The prize, managed by the Japan Society for the Promotion of Science, honors outstanding contributions to research advances in fundamental biology and is one of the most prestigious honors a natural scientist can receive.

Researchers from the United States, Australia, and Europe conducted mesocosm experiments to assess how larval reef fishes respond physiologically and cognitively to low crude oil concentrations. The team observed that polycyclic aromatic hydrocarbons (PAHs), at levels recorded in industrialized sections of tropical coral reefs worldwide, increased larvae mortality and stunted growth rates.
