Well it is getting near to crunch time...

Lucky has be sending signals for over 100 days now (actually more like 104
days, but who is counting). The last tag of this type that has been out
this long transmitted for 111 days ( on "Bubba" the hooded seal...who sent
a total of 1072 locations...Lucky, so far, has sent a total of just under
1000...). So we are getting to the point where we can expect the tag to
fail as its battery runs out of power. For the past two days we have
gotten fewer signals, and fewer that have given us good locations. This
may be simply due to thefact that "Lucky" is far offshore and the signals
are getting blocked by wave action, or it may be a sign that the tag is
finally starting to fail. In any case I am really hoping for at least a
couple of more days of signals. The reason is that for the past few days
"Lucky" has been traveling south from the coast of Maine. He appears to be
moving farther offshore, but generally headed towards the northern coast of
Massachusetts or New Hampshire. His last reported locations were from the
northern edge of Jeffery's Ledge, a very productive fishing area about 25
miles east of Portsmouth, New Hampshire. What is most interesting (and the
reason I would really like another few days of tracking) is that this area
is in the center of all of the north/south tracks that "Lucky" made on his
trips between the coast and Wildcat Knoll. Also, if his last location is
to be believed (it is not a very reliable LC) his direction on his present
track changed abruptly from going west, to going south. Basically, it
looks like he passed over a prominent landmark, that he has crossed before
and made a sharp left turn. It would be very interesting to see if this is
really what he did, and which way his present track takes him.

Keep your fingers crossed and hope that these batteries last for another
few days...
