In the first two issues, we talked about the discovery, rediscovery, development, and ownership of the Spitsbergen Islands, the process of signing the Spitsbergen Treaty, and how China participated in the Spitsbergen Treaty, rediscovered, and built a scientific research station. Clarify the causes and consequences of scientific expeditions to the Arctic on the continent.
China's Arctic Yellow River station in New Ålsund, Spitsbergen Islands
It is precisely because of the dedication of 300,000 dispatched laborers and the unremitting efforts of Mr. Gao Dengyi and countless scientific research and scientific expedition personnel that we have been able to make remarkable achievements in the field of polar scientific expeditions.
Today, we will give you a "hearty expression" through the exquisite design, fantasy color, and novel craftsmanship of the 30-gram silver coin of the polar expedition.
The 30-gram silver coin is exquisite in terms of design and coinage, with the natural beauty of the Arctic and modern Chinese technology forming the main elements of the design. These two elements complement each other in the composition of the picture and are clearly layered. The first thing that catches the eye is the colourful and dreamlike Northern Lights, which give the coin a romantic tone to the picture as a whole. Aurora is a plasma phenomenon that occurs mainly at high latitudes on planets with magnetic fields, and it is not an easy task for most people on Earth to see them with their own eyes. However, the 30-gram silver coin is just a few inches away, showing the beauty of the Northern Lights.
It is estimated that many Tibetan friends have already obtained this silver coin at this time, and those who have not received it for the time being, or who have not won the lottery at all, can take a look at the display video on the official website. Do you wonder how such visuals are achieved?
In fact, this silver coin has achieved technological innovation and upgrading. For the first time, a new full-color fluorescent ink technology is adopted, which is superimposed with various processes such as light scale color and color spray painting, so that it can not only see colorful aurora at different angles under normal light, but also present a more wonderful aurora effect under ultraviolet light.
The photo-changing scale technique was first seen in the 2020 issue of the 24th Olympic Winter Games Gold and Silver Commemorative Coins (Group 1), which caused a big stir in the numismatic world at the time. Nowadays, coinage technology is changing with each passing day, and a precious metal commemorative coin can be combined with a variety of processes, which is a high degree of embodiment of the trend of the times and excellence.
If the viewer shifts their gaze to the left side of the frame, the topography of the Arctic region is unobstructed. The colorful pulsations on the latitude and longitude lines contrast sharply with the colors of the land and sea, further enriching the color expression of the picture. Among them, the point on the right side of the picture represents the Arctic Yellow River Station, and the point on the left side of the picture represents the Sino-Ice Arctic Scientific Research Station. Located in Ny-Ålsund, Spitsbergen Islands, Norway, the Arctic Yellow River Station is China's first Arctic research station, which was completed on July 28, 2004. The Sino-Ician Arctic Scientific Research Station was inaugurated on October 18, 2018, in Kerge, north of Iceland. Both stations are important scientific support platforms for China's scientific expeditions to the Arctic.
