The Universiti Malaysia Terengganu Post-Graduate Conference (UMTPgC) 2023 took place on November 27, 2023, at UMTCC. INOS organized, for the first time, a postgraduate student conference in collaboration with the Faculty of Science and Marine Environment (FSSM), the Faculty of Maritime Studies (FPM), and the Faculty of Business, Economics, and Social Development (FPEPS).
Themed ‘Ocean Sustainability,’ UMTPgC2023 focused on the primary areas of Universiti Malaysia Terengganu involving marine science. The presentations from participants were divided into three main sub-themes: marine science and oceanography, marine environment, and maritime management. These topics are highly relevant for discussion in this academic platform, which includes researchers and industry professionals.

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.
