[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cooling during the last 15 million years of the Cretaceous is widely believed to have resulted in a reorganization of ocean circulation, with cooler periods being associated with deep ocean convection in high latitude regions (e.g., Robinson et al., 2010; MacLeod et al., 2011; Robinson and Vance, 2012; Jung et al., 2013). Understanding the relationship between climate change and sub-surface ocean circulation patterns, and gaining further insight into how circulation dynamics were influenced by the unique Cretaceous paleobathymetry is crucial to furthering our understanding of global climate dynamics during the Late Cretaceous. To provide further insight into Late Cretaceous ocean circulation we used neodymium isotopes as a tool to infer past ocean circulation patterns. Neodymium was extracted from fossilized fish teeth and bone fragments from bulk rock samples at 26 different sites (4 Pacific, 12 South Atlantic, 3 North Atlantic, 3 proto-Indian Ocean). We present two regional studies that focus on Campanian (84-72 Ma) and Maastrichtian (72-66 Ma) circulation patterns in the Pacific (Chapter 2) and South Atlantic (Chapter 3) Oceans. These chapters argue that, by the end of the Cretaceous, climate had cooled enough to support high latitude convection but also that circulation patterns were tightly controlled by bathymetry. To investigate the global implications of these two regional studies we also present preliminary neodymium isotopic data from several sites in the North Atlantic and proto-Indian Ocean (Chapter 4). Further, neodymium isotopic trends were compared to climate model simulations as well as to previously published neodymium, carbon, and oxygen isotopic records.

This study, building upon earlier works published from 2011 to the present, focuses on sixteenth through eighteenth century Cochinchina’s upstream-downstream networked relations and how they contributed to the re-development of the region’s economy and consequently its political and social development, with particular emphasis on its coastal ports and related trade under the Nguyễn. These relations revolve around tightly connected interactions among diverse groups including long-term resident diasporic Fujian merchant communities, newly introduced Chan Buddhist monks, maritime-based Chinese pro-Ming piratical syndicates, local Cham raiding cohorts, and the alien Nguyễn clan who in 1600 claimed political authority over the Vietnamese littoral’s central coastal region (Trung Bộ) and extended central lands (Miền Trung). The partnerships the Nguyễn established with each of these groups (merchants, monks, pirates, upstream and downstream multiethnic communities) enabled the major ports of Đà Năng, and particularly, of Hội An, to thrive and produce the income needed to support both the Nguyễn bureaucracy and its military conquest of the southern third of the littoral. Over the course of the seventeenth and into the eighteenth centuries, the Nguyễn co-opted the cultural, spiritual, and maritime-based power and influence exercised by each of each these groups in an initial effort to fulfill its dynastic ambitions that remained unfulfilled until 1802. This work moves beyond other regional studies by using the approach proposed in Michael Pearson’s writings regarding the Indian Ocean ports-of-trade littoral and extending them eastward, to the further edges of the Indian Ocean borderless world, and applying them to the complex interactions of the Vietnamese littoral populations-coastal urban and hinterland - as they contributed to the development of the central Vietnamese littoral’s ports-of-trade and of Nguyễn authority and power in this era.
