Spa$al Pa(erns of Sea Turtle Nests on Bald Head Island, NC Using Geographic Informa$on Science
Alyssa Randall BHIC Intern 2013
What is GIS? • A geographic informa$on system (GIS) integrates hardware, soLware, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced informa$on.
Understanding Spa$al Pa(erns
Used to make future management strategies
Can reflect past condi$ons Shows the effects of habitat altera$on
Examine areas that are desirable for nes$ng
Data Breakdown • Maps created July 25, 2013 • 99 nest mapped including their metadata • Metadata-‐ “data about data”
– Date Laid – GPS Coordinates – Reloca$on Coordinates – Returning Turtles – Satellite Tagged Turtles – PIT Scan ID – Flipper Tag ID Number – Hatch Date – Hatch Success
Future Research
• Map addi$onal years to see trends and correla$ons in nes$ng on Bald Head Island
• Examine the return rate of turtles based on their PIT tag ID number and flipper tags
• Overlay a beach nourishment layer
Acknowledgements
I would like to thank Jaymie for her support during this process and for providing me with all of the current nes$ng data. I would also like to thank Patrick for providing with the GIS soLware that was needed to carryout my project.
