Persidangan Pasca Siswazah Universiti Malaysia Terengganu (UMTPgC) 2023 telah berlangsung pada 27 November 2023 bertempat di UMTCC.
INOS buat julung kali menganjurkan persidangan pelajar pasca siwazah dengan kerjasama Fakulti Sains dan Sekitaran Marin (FSSM), Fakulti Pengajian Maritim (FPM) dan Fakulti Perniagaan Ekonomi dan Pembangunan Sosial (FPEPS).
Bertemakan ‘kelestarian lautan’, UMTPgC2023 memberi fokus kepada bidang utama Universiti Malaysia Terengganu yang melibatkan ilmu kelautan.
Pembentangan peserta yang dibahagiakan kepada 3 sub-tema utama, iaitu sains marin dan oseanografi, persekitaran marin, serta marin dan pengurusan maritim juga amat sesuai untuk dibicarakan dalam platform akademik ini yang turut melibatkan para penyelidik dan rakan industri.

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.
