In order to broaden the scientific vision of students, understand the cutting-edge knowledge of disciplines, and strengthen the international exchange and cooperation between young students, at the invitation of Prof. Kaifei He of the Institute of Oceanography and Space Information, Dr. Sujata Dhar from the German Geoscience Research Center (GFZ) and Misra Gedik, a postgraduate student from the Boğaziçi Üniversitesi, Türkiye, were invited to our institute for academic exchanges, and had in-depth exchanges and interactions with undergraduate, graduate, and doctoral students in Geodesy respectively. This exchange has received funding support from the China International Talent Exchange Foundation's International Youth Talent Exchange Program (CEP).
On the morning of May 20th, Dr. Sujata Dhar delivered a presentation titled 'A Comprehensive Study on Improving Earth Orientation Parameters (EOP)' at Room 415, South Hall, Tangdao Bay Campus. Dr. Dhar began by explaining that Earth orientation parameters (EOP) are essential for describing the Earth's orientation and rotation in space, including polar motion, diurnal variations, and precession. These parameters are crucial for navigation, positioning, astronomical observations, and Earth science research. With the rapid advancement of space technology, the demand for higher precision in EOP has increased. Current EOP models may not meet the demands of high-precision applications, necessitating comprehensive research to enhance the accuracy and reliability of EOP. Current research methods and technologies include ground-based observations such as Very Long Baseline Interferometry (VLBI) and satellite laser ranging (SLR), as well as space-based observations like satellite gravity measurement and satellite altimetry. Future research will focus on developing more advanced observation technologies and equipment to improve observation accuracy and efficiency, while also enhancing data processing and analysis methods to further improve the accuracy and reliability of EOP models.
Sujata Dhar’s report
Misra Gedik, a master's student at Bogazici University in Turkey, presented a report titled "Seismic Hazard Potential in and Around the Yedisu Seismic Gap: Implications from Seismic and Geodetic Constraints." The report highlighted how integrating geodesic and seismic data can enhance the assessment of seismic hazards in Turkey's eastern tectonically active regions, particularly the eastern segment of the North Anatolian Fault.
Misra Gedik’s report
After the presentation, the two foreign scholars had a close exchange with the teachers and students on site, and patiently answered the questions raised by the students. This academic exchange established new international friendship and academic cooperation, and discussed the possibility of future cooperation in the common research field.
On the morning of May 21st, two international young scholars exchanged ideas and interacted with some master's and doctoral students majoring in Geodesy in Conference Room 402 of the Ocean Building at our university's Guzhukou Campus. After introducing each other, they had in-depth discussions on their respective research directions and progress.
International youth exchange and interaction with master's and doctoral students majoring in Geodesy
The CEP project is initiated by the Ministry of Human Resources and Social Security of China and supported by the China International Talent Exchange Foundation. Its aim is to build an international platform for young talent exchange, promoting mutual understanding, friendship, and growth between Chinese and foreign youth through exchanges. Through this exchange activity, we have established new international friendships and academic cooperation relationships for young students majoring in surveying and mapping at our university, enhanced mutual understanding, and explored the possibility of future cooperation in common research fields.
