Todays locations for "Lucky" have him in pretty much the same location as
yesterday. He seems to be keeping close to the west coast of Ledbetter
Island (Maine). Given the distribution of the locations around the area,
it does ot appear that he is spending a great deal of time hauled out. A
couple of things of interest, however. If you check the tides (see data
below), you will see that many of the "better" "LC" classes (times when the
satellite gets more "hits" and the signal is probably not moving a great
deal) seem to occur around the times of the low tide. This is generally
when seals like to haul out. As it happens, this is also a time of good
satellite coverage for us (and the time when the tag is not shut down for
battery saving), however, if he continues to stay near the coast, it will
be interesting to see if his pattern continues to hold. Also, if you check
back through the archive, you will find that about four of these locations
are the same as locations we have gotten before. All of these "hits" are
quite precise, so we can be fairly sure that these were sent while "Lucky"
was on a small haul out. From this we can get a bit of a picture of what
his activity has been like...basically skipping from small rock to small rock.

This location is also a bit unusual as the water is quite deep close to
shore.

Keep your fingers crossed for how long we will be getting signals, on
Friday we will reach four months of tracking...this makes "Lucky" the
harbor seal we have tracked for the longest period of time.
