We introduce the recent construction and current status of a deep underground microgravity laboratory, YeMiGO (Yemi Micro-Gravity Observatory), in South Korea. On October 2022, YeMiGO was built at the YemiLab in Jeongseon-gun, Gangwon-do Province, eastern mountain region of the Korean Peninsula. YemiLab is the underground experiment laboratory constructed and operated by the Institute of Basic Science (IBS) in South Korea, designed for a dark matter search project. Through a collaboration between the National Institute for Mathematical Sciences (NIMS) of IBS and the University of Calgary in Canada, GWR Instruments Inc.’s superconducting gravimeter, iGravTM (serial #001) was installed in the joint lab, YeMiGO. YeMiGO‘s surface coordinates are (37.190656N, 128.658326E, and 885m above the mean sea level (MSL)), and the gravimeter was installed at about 1,003m and 118m below the surface and MSL, respectively. In this paper, the construction of the lab, installation, and operation of iGravTM, and its current status are presented. Detailed information on calibration, environmental noise characteristics, and its geophysical application will be also presented.
