Abstract: Over the past few decades, scholars, practitioners and activists have expanded the concept of security beyond strict nation-state and militrary definitions. Concurrent to these conceptual developments, the Arctic has become a distinct region of study, with its own environmental, cultural, political, and economic identity. In this paper, we apply a holistic interpretation of security to Alaska's evolving Arctic space. Theoretical concepts of securitization and human security inform a novel matrix of various levels and types of security. Levels range from the local and communal to the international, while types include physical, military, economic, environmental, and cultural security. The matrix serves as a tool to differentiate and synthesize security in a variety of contexts, notably in Alaska's Arctic. To illustrate the utility of the matrix, and to present a more omplete picture of the security environment of the region, we analyze the current expanded port project in Nome, Alaska. In this case, we evaluate the ways in which the proposed project illustrates the complexity of and multiple perspectives on secuirty, while also examining the new challenges of security in a rapidly changing environment with a diverse set of interests focued on the Bering Strait region. This exercise reveals how the expanded port project might remedy some security challenges but exacerbate others.
