on this project, but for the guidance and encouragement necessary to complete my Master's degree. I am eternally grateful for all of his help, insight, and support over the past few years. My committee members, Dr. Milo Adkison and Jim Murphy, were also invaluable assets to the completion and editing of this thesis. This project would not have been possible without the hard work of the crew of the F/V Bristol Explorer, along with the scientific crew who processed hauls, organized data, and were a huge help in many other areas of this research. I would like to give many thanks to Jim Murphy, Emily Fergusson, Alex Andrews, and the technicians at NOAA Ted Stevens Marine Research Institute in Juneau, Alaska, for otolith extractions, sample preparation, and catch maps. I would also like to extend a huge thank you to Karen Spaleta in the Advanced Instrumentation Lab at the University of Alaska Fairbanks for her help and patience when running the ICP-MS equipment. A very special thank you to Nicholas Smith for being my second otolith reader, as well as for statistical help and moral support throughout this process. And finally, I must give all of my love and gratitude to my parents, Randy and Glenna, my brother Anthony, my fiance Benjamin, and all of my family and friends whose unwavering support, encouragement, and belief in me throughout my education has been a major source of inspiration and drive.
