Noisy tests offshore scaring fish away from reefs

January 31, 2017 — The sonic tests used to map the ocean floor in order to explore for oil and gas is scaring fish away from reefs, according to a first-of-its-kind study released by a University of North Carolina at Chapel Hill researcher.

Avery Paxton, a marine ecologist with UNC’s Institute for Marine Sciences, has for two years been studying the effects of loud manmade noises on fish in the ocean.

“These noises, on the reef, they’re repetitive,” Paxton said. “The sound levels on the reef that were heard by these fishes were loud enough that, in laboratory experiments, fish did have physiological damage.”

Substance in crude oil harms fish hearts, could affect humans as well

January 31, 2017 — Research from Stanford University’s Hopkins Marine Station has identified a substance in oil that’s to blame for the cardiotoxicity seen in fish exposed to crude oil spills. More than a hazard for marine life exposed to oil, the contaminant this team identified is abundant in air pollution and could pose a global threat to human health.

The pollutant at the center of this finding, phenanthrene, is a type of polycyclic aromatic hydrocarbon (PAH). Due to widespread use of petroleum, PAHs are also found in land-based stormwater runoff, contaminated soil from defunct industrial sites and air pollution. PAHs have been investigated as cancer-causing chemicals for nearly a hundred years but other potential health effects have been given far less attention. The environmental health risks of phenanthrene, in particular, have received secondary consideration to other PAHs more strongly implicated in the development of cancer.

Gulf Oil Spill Science Outreach Answers Unanswered Questions

July 10, 2015 — Five years after the Deepwater Horizon oil spill, fishermen, visitors and residents of the Gulf coast are still filled with unanswered question about what exactly happened during the spill and the lingering effects. A new oil spill science outreach program now allows Gulf Sea Grant specialists to examine what types of information these target audiences need and develop tailor-made solutions providing answers to these unanswered questions.

With funding from the Gulf of Mexico Research Initiative, and administration by the Gulf of Mexico Alliance, Sea Grant Oil Spill Science Outreach Specialists from Florida to Texas are providing information through free seminars and publications.

“Last fall, the Outreach Team interviewed with more than 500 coastal residents and discovered that residents still had many questions about how the oil spill affected public health, the quality of the water, and the health of the plants and animals living in the Gulf,” said Christine Hale, Texas Sea Grant Oil Spill Science Outreach Specialist at Texas A&M University-Corpus Christi. “People are still concerned with the impacts of dispersants and oiling of habitats such as marshes and beaches.”
