Acoustic bleaching—there’s an expression you don’t hear every day. Whales operate in a world of sound; it is their primary sense. Blue whales make sounds that can be heard thousands of miles away, or at least they used to be able to. Humanity is not just filling our oceans with trash, we are filling our oceans with sound. From commercial shipping, seismic exploration and military testing, the oceans are no longer the silent world that Jacques Cousteau once talked about. Read More
This week marks the end of Operation Toxic Gulf 2014, the fifth and final year of Ocean Alliance’s program assessing the health of the Gulf of Mexico marine ecosystem in a toxicological context through the bio-indicators that are sperm whales. It’s also the end of our second year working in partnership with the Sea Shepherd Conservation Society–what is hopefully the beginning of a long and fruitful relationship from which the true winner will be the oceans, the life which inhabits them, and ultimately our own species. Certainly much of the difficult work has been done, but we cannot forget the hard road ahead of us–the analysis of the data accumulated over the five years of study. When all is done, we should have a comprehensive picture of how the toxicants released into the Gulf of Mexico in the aftermath of the Deepwater Horizon oil blow-out affect the long-term health of marine mammals and hopefully the marine ecosystem, how we can go about protecting it, and how future toxicological catastrophes might better be contained. The next step is to raise the funds for this expensive yet incredibly important data analysis. In the meantime, we have learnt much. The analysis done so far has shown worrying signs. In particular, we have found that concentrations of chromium and nickel in Gulf of Mexico sperm whales are significantly higher than those that we found in whales in other parts of the world, and the dispersant used in the Deepwater Horizon disaster has been found to cause DNA damage and cell death in sperm whale cells at low doses. Perhaps the most important thing is that each and every person who has crewed on the Odyssey in the Gulf has left with a profound sense of purpose about what we are doing and why this type of ocean conservation program is important–not only for the Gulf of Mexico but for the whole world, for the Gulf truly is a microcosm for wider ocean systems. The majesty, beauty, and fragile nature of the Gulf and the extraordinary animals which inhabit it, combined with the ever present and increasingly heavy footprint of man in the shape of the oil rigs, container ships, run-off from the Mississippi and the innumerable and inescapable plastic and visible trash constantly remind us of our connection to our incredible planet and how its fate is inextricably linked to our own. Over the past five years we have accumulated too many thank-you’s to name. Probably over 100 people have crewed these expeditions, with boundless shore support, donors, marina owners, dock-masters, relatives and well-wishers providing support without which the campaigns would not have been possible. On behalf of the crew, let us just say a quick thank you to a few select individuals: to Captain Bob Wallace, the only ever-present who has led the campaigns from the front line and who has kept both crew and boat working efficiently and safely; to the Wise family, who dedicated three entire summers and many hundreds of hours in the laboratory to this program (and more to go); to Sea Shepherd Conservation Society & volunteers, who made the final two seasons possible; and finally to Ocean Alliance CEO Iain Kerr who has, quite literally, run this show (whilst running Ocean Alliance at the same time…). Thank You! -Andy Rogan, Scientific Director for Operation Toxic Gulf 2014
RV Odyssey Captain Bob Wallace has been with Ocean Alliance for over 20 years, has circumnavigated the globe three times, and has more whale stories than all the crew combined. In this video he shares the reasons why he does it.
