Environment: $627 million restoration plan finalized to repair some of the damage from the Deepwater Horizon disaster

Barrier islands, shorelines, dunes, underwater grasses and oyster beds targeted for restoration

Staff Report

FRISCO — Nearly four years after BP’s Deepwater Horizon drilling operation disastrously failed and spewed millions of gallons of oil into the Gulf of Mexico, NOAA and its partners have finalized a $627 million restoration plan. The formal record of decision released last week authorizes 44 projects to restore barrier islands, shorelines, dunes, underwater grasses and oyster beds.

This announcement marks the largest suite of Gulf early restoration projects selected thus far in the wake of the 2010 oil spill. The projects aim to address a range of injuries to natural resources and the subsequent loss of recreational use. Details of restoration efforts are outlined in the Final Programmatic and Phase III Early Restoration Plan and Early Restoration Programmatic Environmental Impact Statement. Continue reading

Study: Exposure to crude oil from the Deepwater Horizon disaster causes swimming deficiencies in juvenile mahi mahi

Evidence is mounting that BP’s oil harmed millions of large fish

FRISCO — Along with fouling beaches and wetlands along the Gulf Coast, the 2010 Deepwater Horizon oil spill also had profound impacts on the open ocean and deep sea environment. The four million barrels of crude oil that spewed into the Gulf of Mexico from BP’s failed oil drilling operation potentially exposed millions of fish and other ocean organisms to highly toxic compounds.

That includes many commercially and ecologically important open-ocean fish species such as bluefin and yellowfin tunas, mahi mahi, king and Spanish mackerels. In one of the most recent followup studies on the impacts of the spill, researchers with the University of Miami Rosenstiel School of Marine and Atmospheric Science found that exposure to the crude oil resulted in decreased swimming performance in young mahi mahi.

Exposure to PAHs disrupts basic cellular function of heart muscles

By Summit Voice

FRISCO — When BP’s failed Deepwater Horizon drill rig spewed millions of gallons of oil into the Gulf of Mexico, scientists immediately began documenting impacts to natural resources, finding dead corals on the seafloor, sick dolphins in Barataria Bay and remnant oil in the splash zone along Florida beaches.

Even low levels of oil pollution can damage the developing hearts of fish embryos and larvae, reducing the likelihood that those fish will survive. Scientists have known of this effect for some time, but the underlying mechanism has remained elusive.

But recent research by scientists with NOAA and Stanford University, shows how oil-derived chemicals disrupt the normal functioning of the heart muscle cells of fish. The findings, published in the Feb. 14 issue of Science, describe how toxic oil-based chemicals disrupt cardiac function in young bluefin and yellowfin tuna by blocking ion channels in their heart muscle cells.

Environment: Dolphins hit by Deepwater Horizon spill are suffering from lung disease and hormone deficiencies

‘”I’ve never seen such a high prevalence of very sick animals …”

Oil from the Deepwater Horizon disaster is making dolphins very ill.

By Summit Voice

FRISCO — Dolphins exposed to heavy doses of oil from the Deepwater Horizon disaster are experiencing lung disease at five times the rate of dolphin populations in other areas, federal researchers reported in a new study published this week. The scientists also found that 25 percent of the Barataria Bay dolphins were significantly underweight and the population overall had very low levels of adrenal hormones, which are critical for responding to stress.

“I’ve never seen such a high prevalence of very sick animals — and with unusual conditions such as the adrenal hormone abnormalities,” said lead author Dr. Lori Schacke, who announced similar findings in March 2012. Continue reading

Environment: Is the Gulf of Mexico resilient to oil spills?

Research suggests role of bacteria has been underestimated

FRISCO — Nearly three years after the Deepwater Horizon drill rig exploded and the busted Macondo Well spewed millions of gallons of crude into the Gulf of Mexico, scientists are still trying to figure out to what happened to all the oil.

Only a tiny amount was captured or burned at the surface, and vast quantity — nobody knows exactly how much — was “dispersed” with chemicals injected directly into the stream of oil streaming out of the broken pipes, but a surprisingly large percentage of the oil may have been broken down by microbes.

Environment: New study shows dispersant makes oil up to 52 times more toxic to Gulf of Mexico microorganisms

Small grazers at the base of the food chain most directly affected

FRISCO — The massive amounts of oil that spilled into the Gulf of Mexico after BP’s Deepwater Horizon drill rig exploded was devastating to marine life, but the dispersant used in the aftermath to try and break down the oil slicks may have been even worse for some species, according to new research done by scientists with the Georgia Institute of Technology and Universidad Autonoma de Aguascalientes, Mexico.

Based on laboratory toxicity tests, the study found that the oil-dispersant mix was up to 52 times more toxic to tiny rotifers, microscopic grazers at the base of the Gulf’s food chain.

The researchers tested a mix oil from the spill and Corexit, the dispersant required by the Environmental Protection Agency for clean up, on five strains of rotifers. Rotifers have long been used by ecotoxicologists to assess toxicity in marine waters because of their fast response time, ease of use in tests and sensitivity to toxicants. Continue reading

New response model needed for deep water oil spills

Scientists urge hard look at oil spill assumptions 

By Summit Voice

SUMMIT COUNTY —Lack of previous experience in deep-water oil spills likely hampered the early response to the 2010 Deepwater Horizon disaster, according to a panel of scientists who this week urged the federal government to reassess how it would respond to similar oil spills that might occur in the future.

The 22 researchers said the 2010 Deepwater Horizon oil spill was unlike any other oil spill encountered previously. Although the well blowout occurred at unprecedented depths and released enormous quantities of oil (an estimated 4.9 million barrels or 206 million gallons), the response to cleanup and contain the oil was based on assumptions made from experience with surface spills.
