An Interdisciplinary Exploration of Deep-Sea Mining in Papua New Guinea

This dissertation, developed in collaboration with the Schools of English and Earth Sciences, critically analyses the contexts surrounding deep sea mining in Papua New Guinea by looking at a failed deep sea mining project, Solwara 1. It argues that a narrow scientific understanding of the seabed fuels extraction attempts, emphasising the cultural narratives and colonial histories that shape perceptions of the deep sea. Ultimately, the thesis provides vital insights into the implications of seabed mining for ocean governance and environmental protection.

The Solwara 1 project reveals significant gaps in current decision-making processes for deep-sea mining, particularly concerning environmental and socioeconomic concerns. It underscores the importance of considering both Western and non-Western perspectives on the deep ocean, revealing conflicts in how these views shape mining practices. Additionally, the study emphasises the need for improved knowledge and legislation to address the emerging challenges associated with mining manganese nodules in areas governed by the International Seabed Authority (ISA).
