New studies show impact of BP's Deepwater Horizon disaster on dolphins and other marine wildlife may be far worse than feared.

A new study of dolphins living close to the site of North America's worst ever oil spill – the BP Deepwater Horizon catastrophe two years ago – has established serious health problems afflicting the marine mammals.

The report, commissioned by the National Oceanic and Atmospheric Administration [NOAA], found that many of the 32 dolphins studied were underweight, anaemic and suffering from lung and liver disease, while nearly half had low levels of a hormone that helps the mammals deal with stress as well as regulating their metabolism and immune systems.

Resilience Alliance

There are many definitions of resilience from simple deterministic views of resilience anchored in Newtonian mechanics to far more dynamic views of resilience from a systems perspective, including insights from quantum mechanics and the sciences of complexity. One baseline perspective of resilience sees it in terms of the viability of socio-ecological systems as the foundation for sustainability. For those that are ready to look beyond resilience as the ability to return to the "normal state" before a disaster, take a look at:

TOKYO (AP) — Japanese whalers caught two animals along the northern coast that had traces of radiation, presumably from leaks at a damaged nuclear power plant, officials said Wednesday.

Two of 17 minke whales caught off the Pacific coast of Hokkaido showed traces of radioactive cesium, both about one-twentieth of the legal limit, fisheries officials said.

They are the first whales thought to have been affected by radiation leaked from the Fukushima Dai-ichi nuclear plant since it was hit by a March 11 earthquake and tsunami.

"The levels are far below the limit, and the meat from the catch is safe for consumption," Fisheries Agency official Kosei Takekoshi said.
