    Below is the data for "Assateague" the hooded seal released by the National
    Aquarium in Baltimore along with the Riverhead Foundation in Riverhead New
    York. I have also attached a map of the data I have so far.

    Good news and not so good news here. The seal was released on the 9th of
    November from Long Island New York. The seal had been transported north to
    get a head start on what should have been a long trip back to home range.
    To meet up with other hooded seals along the east coast, this would mean a
    trip to at least the gulf of the St. Lawrence, south of Newfoundland.
    Sounds like a long trip, but we have seen animals make this trip (see hooded
    seal "Jersey" in the WhaleNet archive).

    After a quick trip offshore immediately after release the track swings back
    to shallow coastal water and heads south. The last signal from the tag came
    from just offshore of Virginia Beach, Virginia on Saturday morning (around
    1500hrs GMT). Since then we have gotten no new signals.

    It is possible that the loss of signals is temporary. If the seal hauled out
    for long enough, the tag would shut itself down. If the seal hauled out and
    rolled on the tag, signals would be blocked. In any case, we should again
    begin getting signals when the tag restarts. The worry is that we have not
    heard for a couple of days, and the longer the tag is silent, the less
    likely it is that we will hear form it again. (the longest I have had a tag
    go silent and show up again?....five days....) At this point all we can do
    is wait and keep our fingers crossed....

    The time that the tag shut down is roughly the time the tag was programmed
    to shut down for the day, so it seems that the tag was working normally at
    the time. The tag is programmed to begin transmission again at 00hrs GMT.

    Whenever we loose signals from a tag, there are only three possibilities:
    the attachment failed (and the tag fell off), the tag malfunctioned (and is
    no longer signaling) or something happened to the seal, and the tag is no
    longer coming to the surface. At this point it is a little too soon to say
    what might have happened, however it is doubtful that the tag would have
    simply fallen off this soon after release. The fact that the tag shut down
    that close to shore makes it seem quite possible that the seal was in the
    process of hauling out when the tag shut down, but we will have to wait to
    see what happens from here.

    Hopefully I'll be back to you with more later this week....

    Keep your fingers crossed...
