Victory! 2nd Coal-Fired Power Plant Defeated in Chile

For the second time in less than a year, Oceana has helped to defeat a coal-fired power plant on the coast of northern Chile. The CAP company announced last week that it was withdrawing its plans to construct the Cruz Grande thermoelectric power plant.

Cruz Grande was slated to be a 300-megawatt thermoelectric power plant in the region of La Higuera in Northern Chile, a few miles from the Choros-Damas and Chañaral island marine reserves, and near the Humboldt Penguin National Reserve, which is home to the world’s largest population of Humboldt penguins. The region also hosts communities of bottlenose dolphins, marine otters and many marine birds and mammals, including blue whales.

These creatures and habitats were at risk from the plant’s emissions, which would have arrived quickly to the reserves. The plant would have used the area’s seawater to cool the plant, discharging it back into the ocean at higher temperatures. Oil spills from ships carrying coal to the plants would seep there in a few hours, and the local currents would retain the pollution within the area. Plus, mercury emissions from the plants would contaminate fish and mollusks like the Chilean abalone, damaging a crucial local industry.

Expedition Wildlife Spotting, Part 2

On my second attempt to spot whale sharks yesterday, I flew with the effervescent Bonny Schumaker, whose organization On Wings of Care helps protect wildlife and their habitats by helping with search, rescue, rehabilitation and scientific research. Samantha Whitcraft of the non-profit Oceanic Defense also joined us for the flight. We took off from New Orleans and flew about 50 miles south over the Gulf.

Bonny and her 4-seater plane, whom she lovingly refers to as “Bessie,” have years of experience spotting wildlife.  Unfortunately, despite Bonny and Bessie’s best efforts, the conditions yesterday were simply not ideal for finding marine life. Choppy waters and white caps made it a challenge to see much of anything besides oil rigs, oil boom and barrier islands:

Can You Hear Me Now?

A recent study conducted at the University of Hawaii provides “sound” evidence that sonar induces temporary deafness in bottlenose dolphins. Many have long blamed man-made noise -- mainly sonar used by the navy -- for mass strandings of whale and dolphin species. Although this study does not provide concrete proof that submarine and warship sonar activity is causing strandings, it does prove definitively that sonar activity can affect cetaceans if they are close enough to the source and exposed over a prolonged period of time. Whales and dolphins use sound for navigation and temporary deafness can leave them disoriented. They are traveling over very large distances and cannot afford to lose their sense of direction. If they were to accidentally swim into a shallow area or be washed ashore, they could rapidly become dehydrated and die.
