Speech Title: Transient Electromagnetic Sounding Method and Its Application
Abstract：The transient electromagnetic sounding method plays an important role in oil and gas exploration, mineral resources exploration, engineering geophysical prospecting, groundwater exploration, shallow structure exploration and reservoir dynamic monitoring due to its flexible acquisition device, free from high-resistance layers, pure secondary field observation after power outage and the ability to enhance the signal-to-noise ratio through superposition. This article introduces the role of the central loop transient electromagnetic method in shallow structure exploration and surface structure investigation. Studies have proved that the shallow transient electromagnetic sounding method features high resolution, large effective exploration depth (up to 300 meters), strong anti-interference ability, low cost, and high efficiency. Besides, this method directly measures the magnetic field, so no static displacement exists; The resistivity-depth profile inverted by the transient sounding method has rich electrical characteristics, and the layering characteristics are richer than the velocity parameters. The electrical difference in the surface structure is greater than the velocity difference. Therefore, the use of electrical parameters to understand lithology is better than velocity parameters. The velocity and layer thickness parameters obtained by using the transient electromagnetic method to invert the resistivity profile are used for seismic static correction velocity modeling, the calculation of static correction amount, and seismic static correction, so as to achieve micro-logging and small refraction static correction. The results provide an effective method for solving the seismic static correction problems in the loess plateau and desert in western region of China.

Speech Title: Arctic Shipping Passages and Chinese Arctic Shipping Activities
Abstract：Acrtic waters exist in harsh environment, which is unexploited place far away from mainland. As temperature increases in the worldwild, time window to allow Arctic shipping operations increase as well. This provides a gold shipping line for China and will boost chinese economy. This report will focus on artic passages,temperature,ice conditions, main ports, control policies and so on. The information on commercial shipping activities through Arctic passages in China is summarized. The related risk and chanlleges are also included.
