Recently, Laboratory for Regional Oceanography and Numerical Modeling (hereinafter referred to as the Lab) of QNLM and Oceans and Atmosphere Flagship of Commonwealth Scientific and Industrial Research Organization (CSIRO-OA) have completed their first joint cruise. Using the scientific research vessel Offshore Limitless, a set of deep sea Bailong buoy and 8 Argo floats have been successfully deployed in the international area to the northwestern Australia.

The joint cruise is one of the campaigns of Years of the Maritime Continent (YMC), also supported bythe Centre for Southern Hemisphere Oceans Research (CSHOR, QNLM’s overseas research center). It will serve for the study on upper ocean dynamics over the tropical southeast Indian Ocean and interactions between tropical Madden-Julian Oscillation and Australian Monsoon onset. Through high-frequency observation, collection and real-time transmission of sea surface meteorological and subsurface ocean environmental data, the dynamic processes and air-sea interactions during the Australian Monsoon transition can be monitored in real time. More information about the joint cruise is available on the official website of YMC (http://www.jamstec.go.jp/ymc/campaigns/IOP_MAMOS_CSHOR.html).
Deep sea Bailong buoys were previously deployed in the critical area of the Asian Monsoon onset and shared by the forecast centers around the world. For the first time, the Bailong buoy has been deployed in the critical area of the Australian Monsoon Onset and been able to monitor the ocean dynamics and air-sea interactions during the Australian Monsoon transition in real time. It will provide powerful data support for the in-depth study on the unified theory of Asian-Australian Monsoon Onset.
This joint cruise is probably the most difficult one for the buoy team of the Lab in their career. Most of the members suffered severe seasickness because of the tough environment and limited operating conditions. Tough as the conditions were, the buoy team struggled to accomplish the task smoothly.The members of this scientific investigation include DUAN Yongliang, WANG Huiwu, LIU Jianjun, LI Chao and YANG Yang who are with the Lab and the Australian engineer Ryan Crossing and post-doctor Je-Yuan Hsu.
