What We've Found So Far in the Gulf
Our main objective in the Gulf of Mexico is to obtain biopsy samples from sperm whales to determine how the Deepwater Horizon disaster is affecting these animals at the top of the food web. Each year since the spill we’ve collected approximately 50 sperm whale biopsies from the Gulf, the last two years thanks to support from Sea Shepherd Conservation Society. From 2000-2005 the Voyage of the Odyssey collected biopsies from sperm whales around the world, so we’re able to compare the samples from the Gulf with the rest of our samples. So far, our partners at the Wise Laboratory of Environmental and Genetic Toxicology at the University of Southern Maine have published two studies in scientific journals from our Gulf sperm whale samples. They are:
Concentrations of the Genotoxic Metals, Chromium and Nickel, in Whales, Tar Balls, Oil Slicks, and Released Oil from the Gulf of Mexico in the Immediate Aftermath of the Deepwater Horizon Oil Crisis: Is Genotoxic Metal Exposure Part of the Deepwater Horizon Legacy? (Environmental Science and Technology)
Chemical dispersants used in the Gulf of Mexico oil crisis are cytotoxic and genotoxic to sperm whale skin cells (Aquatic Toxicology)
In addition to these studies are the thousands of photos and the data collected that illustrate what an important habitat the Gulf of Mexico is for whales and dolphins. It is our goal to bring these animals to the forefront of people’s attention when they think of the Gulf, rather than the oil rigs that dot their landscape.
