Well this could be more difficult that planned. So far we are getting
signals from the tag on Gray, but have had fairly few good location fixes.
We appear to be getting a day or so of good locations, then a day or so
with no locations. We have had similar problems tracking other seals in
this area, and have generally written it off to rough sea conditions. Our
latest locations (from a day ago) show Gray near the center of the mouth of
the Bay of Fundy. This is an area of strong tides and currents, and may be
having an effect of the way he is swimming (which , in turn is making it
difficult for the tag to send good signals). This is just a guess, but it
seems to be supported by the pattern of signals we are getting. We may be
getting better transmission on days when he is headed in one direction, and
poor transmission when he is headed in another direction. Ifthis is the
case, it would also mean that he has been changing direction frequently or
circling. At this point only time (and some luck) will tell.

Keep your fingers crossed....I am still getting signals as of today, so I
know the tag and Gray are still out there...somewhere...
