In findings from new study released this week, researchers from the University of California, Riverside and the University of Miami Rosenstiel School of Marine and Atmospheric Science reported that old, weathered oil from the spill is even more toxic than fresh crude oil. Ultraviolet light changes changes the chemistry of the oil, the scientists said, further threatening numerous commercially and ecologically important fishes.
Report says more monitoring of wildlife needed on offshore oil drilling rigs
It only takes exposure to a teaspoon full of oil to kill some seabirds, but oil drillers off the coast of Canada are failing to adequately monitor small, persistent spills that can lead to chronic pollution and population-level impacts, according to a new study by scientists with York University.
The research published in the international journal, Marine Pollution Bulletin, looked at how offshore oil operators monitored and responded to small spills (less than 1,000 litres) for three production projects off the coast of Newfoundland and Labrador. It came after authorities failed to respond to three high-profile environmental assessments by Environment Canada that requested impacts on seabirds be monitored following small spills.

Exxon Valdez oil spill fingered in decline of herring, salmon populations
FRISCO — Long-term research that followed up on the impacts of the 1989 Exxon Valdez oil spill suggests that fish and other marine organisms may feel the effects of low levels of toxic crude oil for much longer than previously believed.
The new study shows that embryonic salmon and herring exposed to very low levels of crude oil can develop hidden heart defects that compromise their later survival. The findings, published this week in the online journal Scientific Reports suggest that the delayed effects of the spill may have been important contributors to the decline of some fish populations.

Offshore wind energy projects touted as better alternative
FRISCO — Cities along the southeastern coast of the U.S. are lining up to oppose offshore fossil fuel exploitation. Earlier this week, the Morehead City Council unanimously passed a resolution opposing seismic airgun blasting and offshore drilling.
The council’s resolution expresses concerns that federal plans for offshore oil and gas exploration and development threaten coastal communities, economies, fisheries and marine mammals.
Lacksadaiscal enforcement is a recipe for disaster
FRISCO — After a series of disastrous pipeline breaks, the National Wildlife Federation says it’s time to hold the federal government accountable for its failure to enforce basic requirements like regular inspections and update safety response plans for pipeline accidents.
This week, the nonprofit group said it will sue the U.S Department of Transportation in an action that has nationwide implications, since nearly every pipeline that crosses a navigable water is operating illegally. In its formal notice of intent to sue, the National Wildlife Federation is asking the Department of Transportation to issue regulations for oil pipelines in water, and require every owner and operator of an oil pipeline in a navigable water to submit a safety response plan that needs to be approved.
