Expedition Report Transport Indonesian seas, Upwelling, and Mixing Physics (TRIUMPH) 2019 Leg 1 & Leg 2 (37 Days) November 18th – December 24th 2019 Prepared by: Center of Deep-Sea Research, Indonesia Institute of Science LIPI (CDSR LIPI), Indonesia The First Institute of Oceanography, MNR (FIO MNR), China University of Maryland (UMD), USA Version 1, December, 24th 2019 EXPEDITION REPORT OF THE PROJECT: “TRansport Indonesian seas, Upwelling, and Mixing PHysics (TRIUMPH) 2019” Executive Summary The Indonesian seas provide a low-latitude pathway for the transfer of warm, relatively low salinity Pacific waters into the Indian Ocean, known as the Indonesia Through-flow (ITF) which has impacts on the basin budgets of the Pacific and the Indian Oceans. Indonesian seas host the strongest equatorial convective center that drives the global tropical circulation (Walker Circulation), which affects Madden-Julian Oscillation (MJO), Asian-Australian monsoon and interacts with El Niño-Southern Oscillation (ENSO). Indonesia Through-Flow (ITF), flow through several waters in Indonesia seas like Seram Sea, Banda Sea, Makassar Strait, Lombok Strait and Eastern Indian Ocean which classified as deep ocean. The Makassar Strait, Lifamatola Strait / Seram Sea, and Karimata Strait are three main inflow passages and Lombok, Alas, Sape Straits, and Timor passage are the exit pathways of the ITF which transmit water masses from the Pacific Ocean to the Indian Ocean and also transform the water mass by mixing and intensive internal-wave generation. The deep ocean is a dynamic, yet poorly explored system that provides critical climate regulation, host a wealth of hydrocarbon, mineral, and genetic resources, and represent a vast repository for biodiversity. Today human activities associated with the extraction of energy and living resources routinely extend into deep ocean, and new deep-sea industries such as seabed mining, gas hydrate extraction, and bio prospecting are on the horizon. In order to improve the understanding of the transport in the ITF input passages, the mixing along the exit passages, the upwelling in Eastern Indian Ocean, and contribute to improve understanding of the state of the deep ocean to characterize existing condition and quantify the response to climate variability and human disturbance as well as benefit the people living in this area, we conduct the Transport Indonesian Seas, Upwelling and Mixing Physics (TRIUMPH) Research Program. The data acquired in the Indonesian EEZ will be owned by the Indonesian Government and the partners will have the copy of data. The transfer of materials outside the Indonesian Territory will be done following a Material Transfer Agreement. Publication of the results in peer-reviewed international journal and other publications shall be done together between parties. The author list should be based on their scientific contributions. The TRIUMPH II Team is an international research collaboration of the Indonesian Institute of Sciences (LIPI), First Institute of Oceanography (FIO) and University of Maryland (UMD). We are welcome to collaborate with many scientists from various research Institutions both internal or external of LIPI and universities in Indonesia to participate and involved actively with this TRIUMPH research program.
