Hello all,

Thought you might like an update from this weekend.  Attached are the
locations so far from the harbor seal.  Things look good with the tag and
the seal appears to be settling into an area around Bustins Island
(Harpswell area).  There is quite a scatter to the locations so far, but
they appear to be clustering in that area.  The dive data is showing quite a
lot of dives (60-70 per six hour sample).  These are mostly shallow, and
fairly short dives.  Given where she is, she is probably going to the bottom
in these areas.  (Most of the dives are up to about 20 meters, between two
and five minutes).  We will be looking to see if a regular pattern of diving
develops.  This would indicate feeding (we hope).  It looks like she also
hauled out (probably for a good deal of time on the 12th).  As we decode
some of the surface time data I should be able to do better with how long
she has been hauling out and when.  If she follows a textbook pattern of
haulout, she should haul out about every other day or so.  We have gotten
about 120 dive data messages so far.  I've taken a quick look at the
duration information.  We have  duration data on about 1132 dives so far,
close to 70 % of those dives are less than 2 minutes long, however she has
done some dives over 20 minutes long and in the past few days she appears to
be doing  more dives between 2-5 minutes long.  (about 28% of her dives are
in that range).  The only concern right now is that the tag is sending
signals at it's maximum rate.  At this rate we figured the tag might only
last about two months, however we will see, the more time she spends in the
water the fewer transmissions the tag sends 

As for the Kiwi.  We have only gotten one data message this weekend.  With
our last hooded seal we did not receive much data for the first week or so
and did not get a good location for about ten days so it is still too soon
to tell quite what is going on.  The good news is that the tag is
functioning so if she hauls out we will know.  The bad news is that we have
not seen any dive pattern yet so we can't really tell what she is doing.  

Keep your fingers crossed.
