To answer your second question, the approach we've taken is to systematically eliminate some of these reasons or potential causes for why the eelgrass is disappearing.
We have studied some literature by other people as well, not just this individual we're using. We wanted to take somebody who was totally independent from the developer to see if we could come up with the information. I believe that some of the people who work for the developers, in this case Hydro-Québec, have a tendency not to bite the hand that feeds them. The outcomes of some of the studies in the case of the developer are basically self-serving. Dr. Short was the only individual we found who has been totally independent from Hydro-Québec. There are not too many experts in this field.
