OTGA Training Course: Foundations of Coastal and Marine Spatial Planning | 18-22 November 2018

Overview Increased activity in the coastal and marine environment has led to two important types of conflicts in the region: (1) conflicts among human uses (user-user conflicts); and (2) conflicts between human uses and the coastal and marine environment (user-environment conflicts). These conflicts weaken the ability of the ocean to provide the necessary ecosystem services […]

Abstract

While the sinking formation of Antarctic Bottom Water (AABW) is well understood, how this bottom water "returns home" through upwelling within ocean basins, particularly the Indo-Pacific, remains shrouded in uncertainty. In the 1960s, Munk’s classic "Abyssal Recipes" theory sought to explain these abyssal flows, yet later observations exposed two significant conflicts with real-world data. In 2016, Ferrari, McDougall, and colleagues proposed the "Towards a New Abyssal Recipe" framework, introducing bottom boundary layer (BBL) upwelling to address Munk’s inconsistencies. Drawing on recent evidence of a potential cooling trend in the deep ocean, this talk revisits these debates, offering a fresh interpretation of Munk’s discrepancies and proposing a new mechanism for abyssal upwelling in the Indo-Pacific. It contributes to the ongoing quest to unravel how bottom waters complete their global journey.
