After a little over a week, I have some location information on "Gray" the
gray seal that was released on May 24 from Cape Elizabeth, Maine, by the
Marine Animal Lifeline (thanks guys)...

So far...it looks like we may be in for a tough time. In general, however
the first week or so is usually difficult. It seems that for some reason
(likely the seal is moving quickly and erratically) we do not get many
location "hits" immediately after a seal is released. So far we have been
getting one or two locations per day from "Gray", but over the past day or
so, it appears to be improving (a bit). We may also not be getting as many
signals because "Gray" is not sending as many. If a seal is spending a lot
of time peering around at things (with his head up and tail down), the tag
will not clear the water well and is not likely to send very many signals.
If this is all that is going on, the good news is that if the seal hauls
out, we will get many more signals, and at least know where and when he
might be out of the water. So far, there is not indication that "Gray" has
been out of the water, although he has probably been within sight of the
coast.

Briefly...The first few signals in this group are from me testing the
tag...(no "Gray was not in Boston Harbor). His first post release point
put him at the entrance to Portland Harbor. It is hard to say how accurate
that location was, and certainly that was not the direction that we wanted
him to go. However over the next several days, Gray headed down (that
would be north along the coast) the Maine coast getting as close as a mile
or so, to shore and as far as fifteen to twenty miles offshore. He seems
to be mostly staying ten miles or so offshore over moderately deep water,
and moving slowly along the coast. His most recent positions put him
roughly off the coast (about 15 miles off the coast) of Jonesport, Maine.

What do we expect? Well...there are groups of gray seals both to the north
and south of his release location (off of islands east of Cape Cod...and
along the coast of Maine). The largest groups of gray seals are located
off of the east coast of Nova Scotia. It is possible that Gray was born in
any of these places. So far he has passed by an area where gray seals are
found (Mt. Dessert Rock) and is near the mouth of the Bay of Fundy. To do
this, he is probably swimming against the prevailing and tidal currents in
the Gulf of Maine.

What might be next? Well, this may be a rough ride...He may head north
into the Bay of Fundy, east around the coast of Nova Scotia, or West
towards the coast. If he heads to the coast in this location, he will be
in an area heavily populated with fish farms...not a good place to be if a
seal is going to stay out of trouble.

So...keep your fingers crossed...hopefully we will be getting more
data...and we can keep you up on his latest moves...

Stay tuned...

ps

The attached pictures...one is a "before" one is an "after"...one is an
"after with the tag"....

note the orange marks in the before picture are marks put on him by the
folks that rescued him to remind them where some of his injuries were...
