Tracking changing water budgets across the Bahamian archipelago

Abstract Because of the scarcity of observational data, existing estimates of the heat and water budgets of the Persian Gulf are rather uncertain. This uncertainty leaves open the fundamental question of whether this water body is a net heat source or a net heat sink to the atmosphere. Previous regional modeling studies either used specified surface fluxes to simulate the hydrodynamics of the Gulf or prescribed SST in simulating the regional atmospheric climate; neither of these two approaches is suitable for addressing the above question or for projecting the future climate in this region. For the first time, a high-resolution, two-way, coupled Gulf–atmosphere regional model (GARM) is developed, forced by solar radiation and constrained by observed lateral boundary conditions, suited for the study of current and future climates of the Persian Gulf. Here, this study demonstrates the unique capability of this model in consistently predicting surface heat and water fluxes and lateral heat and water exchanges with the Arabian Sea, as well as the variability of water temperature and water mass. Although these variables are strongly coupled, only SST has been directly and sufficiently observed. The coupled model succeeds in simulating the water and heat budgets of the Persian Gulf without any artificial flux adjustment, as demonstrated in the close agreement of model simulation with satellite and in situ observations. The coupled regional climate model simulates a net surface heat flux of +3 W m−2, suggesting a small net heat flux from the atmosphere into the Persian Gulf. The annual evaporation from the Persian Gulf is 1.84 m yr−1, and the annual influx and outflux of water through the Strait of Hormuz between the Persian Gulf and Arabian Sea are equivalent to Persian Gulf–averaged precipitation and evaporation rates of 33.7 and 32.1 m yr−1, with a net influx of water equivalent to a Persian Gulf–averaged precipitation rate of 1.6 m yr−1. The average depth of the Persian Gulf water is ~38 m. Hence, it suggests that the mean residency time scale for the entire Persian Gulf is ~14 months.

Domestic Landscapes

Archaeology of Domestic Landscapes of the Enslaved in the Caribbean examines the diversity of living environments that the enslaved inhabitants of the colonial Caribbean by analyzing archaeological evidence collected from a wide variety of sites across the region. Archaeological investigations of domestic architecture and artifacts illuminate the nature of household organization; fundamental changes in settlement patterns; and the manner in which power was invariably linked with the material arrangements of space among the enslaved living and working in a variety of contexts throughout the region, including plantations, fortifications, and urban centers. While research in the region has provided a considerable amount of data at the household-level, much of this work is biased towards artifact analysis, resulting in unfamiliarity with the considerations that went into constructing and inhabiting households. The chapters in this book provide detailed reconstructions of the built environments associated with slavery and account for the cultural behaviors and social arrangements that shaped these spaces. It brings together case studies of Caribbean slave settlements through historical archaeology as a means of exposing the diversity of people and practices in these various landscapes, across the British, French, Dutch, and Danish colonies in both the Greater and Lesser Antilles as well as the Bahamian archipelago.
