Chair Professor Jian Lin’s research team from the Department of Ocean Science and Engineering at the Southern University of Science and Technology (SUSTech) has recently collaborated with Professor Jiabiao Li’s team from the Second Institute of Oceanography (SIO) at the Ministry of Natural Resources (MNR), as well as scientists from the South China Sea Institute of Oceanology, Chinese Academy of Sciences, and the Institut de Physique du Globe de Paris (IPGP) in France. Together, they have published a groundbreaking study in which, for the first time, they successfully broke through the ice cover and conducted a high-resolution ocean-bottom seismometer (OBS) experiment in the extreme environment of Gakkel Ridge in the Arctic Ocean. Their research proposes that both active and passive mantle upwelling control the global mid-ocean ridge system.

Their paper, entitled “Highly variable magmatic accretion at the ultraslow-spreading Gakkel Ridge”, has been published in Nature.

This discovery challenges the long-held belief that magmatic supply at ultraslow-spreading ridges is limited. These results not only advance the understanding of the theory of tectonics plate dynamics but also highlight the increasing contributions of Chinese scientists in the field of Earth Sciences.
