No, not specifically on the southern resident killer whale.
Fortunately, in the inner water of their critical habitat as recognized both in the U.S. and Canadian waters, there are no seismic operations, which, like sonar, have a potential impact on the animals. There's no exploration for hydrocarbons in those particular areas. We're more concerned about what the animals may face when they're out off the west coast of Vancouver Island and the west coast of Washington and extending up into Alaska. Certainly in those areas they have potential to encounter military sonar and sounds from seismic operations, and those are of concern but not actively being investigated as impacts on that population.
