Gipe Callovian (upper Middle Jurassic) Magnetostratigraphy: A composite Polarity Pattern from France, Britain and Germany, and its correlation to the Pacific magnetic anomaly model ii ACKNOWLEDGEMENTS I would like to thank my advisor, Professor James Ogg, for support and guidance through this project. I would like to thank Professor Masako Tominaga for providing me with the amazing opportunity to participate on the 2011 Jurassic Ocean Crust Magnetic Survey. I would also like to thank her for being on my committee and for providing valuable insights into geophysics and the study of the Earth's geomagnetic field. A sincere thanks also goes to Professor William Zinsmeister for taking the time to serve on my advisor committee. Analytical facilities were generously provided by the paleomagnetic laboratories at the I would particularly like to thank my friend and family for the support they provided me through my graduate work at Purdue University.
