Data

Sweet Pea was released May 14, 2002

Data - No data received thus far.

Why do we have no data on Sweet Pea?

Possible reasons:

1) The tag fell off of the turtle.

2) The orientation of the tag does not allow the attenna to clear the water level when the turtle comes to the surface to breathe.

3) The salt water switch which turns the tag on to transmit to the satellite was covered by the expoy.

4) The antenna was damaged in transit or during preparation or placement.

5) The satellite tag was damaged in transit after the successful test in Massachusetts.

C. What questions would you ask about the satellite tag application process?


A successful tagging event.

Sweet Pea's tag.
