Data Format
Date (dd.mm.yy): 22.08.96 23:06:55 Time (hr:min:sec)(in GMT), LC (fix quality)
LC just stands for Location Class. Location Classes of 0 and up are the best (derived from 4 or more messages)- a Class 0 is good to within between 1,000 and 5,000 meters. Classes 1,2,3- get consistently more accurate. The letter classes are given no estimate of error, but the A's are better than the B's etc. It appears that some of the letter class locations are pretty good (i.e. several fixes over a short period are quite similar), but then others vary wildly- especially the longitude.

Final Report

Our last message from "Casino" was six days ago. Although we did get a location that looked pretty good the dive data from the tag was very strange (probably due to the power ( I hope). I will be doing some double checking on those messages, but I think we can be fairly sure that we will not be hearing from the tag again. Given the power readings from the tag that we have been getting I think it is safe to assume that the tag has run out of power and shut down. All things considered this was a very interesting and valuable tag run. We received 78 days of data, 299 location fixes. The locations covered a distance of over 2,600 miles(how many miles per day does that work out to?) within a range of over 25,000 miles. We received over 2300 data messages. From those messages we collected over 750 data messages that gave us data on dive duration and dive depth for over 130,000 dives. We will be crunching up the numbers for a while, but I will send along a summary of what we think went on, once we have had a chance to look at the data a little more closely.
The short version of the story is that "Casino"'s track can be broken into at least three main parts. First he travel led across the Gulf of Maine. This is an important finding, because so far all of the released seals we have tagged have left the release location very quickly. This is important, because, it probably tells us why we so infrequently get follow up information from tagged, rehabilitated seals..they leave...fast. Second he moved up the coast of Nova Scotia staying well offshore doing fairly deep and consistent dives. For the last thirty or so days he as moved north, up the coast, then south along the coast staying near shore, doing shallower dives and hauling out frequently. We can certainly say that "Casino" survived following release for the full 70+ days of tracking. I think we may be able to make some educated guesses at how well he may do in the future by looking at the dive data, however that will have to wait until I can look more closely at the data Basically, though, this will be the last message about "Casino".
