The science is a critical element of how we respond to incidents. Understanding the behaviour of substances in the water is critical in terms of knowing how to respond. Knowing what the habitat is in the area and all those kinds of things are critical to an effective response.
With regard to derelict vessels, we're working with Transport Canada now to look at how to manage the derelict vessel problem. Certainly with the cost for remediating a 100-foot vessel varying between $10 million to $50 million it is a significant problem. It is about the owner of the vessel being responsible, absolutely. Some sort of sanction to force owners to be responsible for their vessels is critical.
