Sighting Data

January 28 (Friday) CCSN and NEAq responded to a total of 17 live stranded dolphins. 3 Whitesided, 14 commons: 3 died, 7 were euthanized, 2 were relinquished to the rising tide, and five were transported and released. NEAq was able to satellite tag another Dd prior to release They are getting good data already on the critter (another Dd) they tagged last night...one of three released at the time)

Data Format key:
Date (dd.mm.yy): 22.08.98 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. (Argos Accuracy Table) 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.

2. How far did it travel since its initial tagging?
3. Why do you think it is traveling in a particular direction?
4. Why do whales/porpoises/dolphins migrate?
5. What is the average rate of travel?
6. What other questions do you have?
7. How would you find your answers?
8. What other information would you need?
