      What is the abyss? Why should we research it? Why is it named after Rainbowfish? And what’s the current progress of Rainbowfish challenging the extremes of hadal zones? On June 6th , the third lesson Dedication to China Series Courses was lectured by Shanghai Jian Qiao University in auditorium. We were much honored to invite Weicheng Cui, one of the first batch of Shanghai Jiao Tong University’s Distinguished Professors in Chang Jiang Scholars Programme and vice project leader who directed the research of the Jiaolong Deep Submersible to 5000m depths on the scene and one of its three test aquanauts, as well as the director of Science and Hadal Technology Center in Shanghai Ocean University currently, to present the story behind Rainbowfish’s  challenges to the extremes of the hadal zones, and share his “ocean technology dream” with teachers and students of our university.

       Professsor Cui initially introduced us the classification and its the latest definition of depth intervals and hadal zones given by the International Maritime Community and International Organizations. He put that there was an apparent difference between the creatures existing in the hadal depths of 6500m-11000m and above the depths of 6500m. Therefore, the Ocean Science that specializes in bucket range is defined as Hadal Science, including abyss ecology, abyss biology, abyss geology etc. Although the Hadal Science is the weakest link in the Marine Science researches, it’s considered to be the frontier of Marine Science due to the dependence on Marine High Technology.

      “Though we’ve been confronted with a number of difficulties, we adjust to changing circumstances, guaranteeing the progress to be carried forward as planned. As a result, the actual effect is even better than what we expected”, Professor Cui said whilst introducing the current progress of Rainbofish from platform preparation, team building, technology breakthrough, experience accumulation, government support etc. Professor Cui also disclosed that Rainbowfish Manned Submersible would set out to Mariana Trench, completing the ultimatechallenge to be the best manned submersible which can dive into the deepest hadal trench by 2020. “We and even the whole team ought to buckle down to accomplish the “tough task” whole-heartedly.

        Never can we lower our guard on every step, including equipment purchase, data gathering, integration, debugging and sea trial.” Professor Cui added as well.
