China s 39th Antarctic Expedition Sets Sail, What Questions Will This Expedition Focus? What researc

The expedition will focus on climate issues and will be devoted to glacial sedimentary studies.

In general, China's 39th Antarctic expedition has set sail, which will focus on the issue of climate change and take glacial sedimentation as the main research direction. Because climate and environmental issues are the most important now, and Antarctica can directly reflect these problems, this Antarctic expedition focuses on climate issues. Specifically, these studies are to be conducted:

Glacial sedimentary studies, atmospheric composition studies, Antarctic ecology studies. The following explains in detail.

Clause. 1. China's Antarctic expedition will focus on climate change and conduct glacial sedimentary research: because climate change will directly affect Antarctic glaciers, glacial sedimentary research will specifically understand what changes have been made in glaciers, so as to clarify what changes have occurred in the climate and environment.

So it is necessary to carry out glacial sedimentation research. Because the amount of glacier sedimentation is a dynamic data, it is possible to observe the dynamics of the glacier from this data. If the amount of sediment becomes smaller, it means that the glacier sediment is less than dissolved, and the greenhouse effect is worse than the dissolution.

It can be seen that this expedition will carry out glacial sedimentation research.

Clause. 2. The Antarctic expedition will conduct in-depth research on climate issues and study the composition of the atmosphere: because the proportion of carbon dioxide is an important indicator for studying climate issues.

Therefore, it is important to accurately detect the proportion of carbon dioxide. The South Pole is located at the poles of the earth and is least affected by atmospheric circulation, so the proportion of carbon dioxide fluctuates the least and is the most stable. Therefore, China's Antarctic scientific expedition will conduct research on atmospheric composition.

Clause. 3. Climate change has a great impact on the Antarctic ecological environment, and it is necessary to conduct Antarctic ecological research: climate change is not an isolated change, it will cause certain consequences, and this consequence will first be reflected in the deterioration of the Antarctic ecosystem.

Therefore, it is necessary to conduct Antarctic ecological research. These include changes in the migration of Antarctic animals, changes in the composition of the oceans, and so on, so as to understand the consequences of climate change. Therefore, it is necessary to conduct Antarctic ecological research.

The 39th Antarctic Expedition will focus on major scientific issues such as the response and feedback of key sea areas in the Southern Ocean to global climate change, and carry out investigation and research in related fields such as atmospheric composition, water environment, sedimentary environment, ecosystem and other related fields.

It is mainly to study the problem of life under Antarctica, and it will also ** the current rate of ice melting in Antarctica and the environment in which penguins grow.

Investigation and study of the main atmospheric components, water environment, sedimentary environment, and ecosystem.

China's 37th Antarctic scientific expedition triumphed, and netizens welcomed the scientific heroes home. The continent of Antarctica has a very unique geographical feature, after all, the continent is covered by ice sheets. And because of the unique climatic conditions and geographical and geological conditions, there are also some scientific secrets that people say they don't know about waiting for people to unveil its mystery, and the creatures here also have particularly rich and unique characteristics, and the significance of scientific investigation is huge.

Scientific research

The National Interest

Macro configuration

First, the significance of scientific expeditions is to study the scientific information collected The main significance of scientific expeditions in Antarctica is to collect local geographic information, as well as to study local biological changes and climate change, which are very important for studying the changes of the earth over thousands of years. Moreover, the investigation of biodiversity is also necessary for the study of the world's ecological environment and the evolution of the world's flora and fauna. The reality is that countless scientists have discovered results in Antarctica, such as some prehistoric biological remains, ancient viruses and so on.

Second, national interests are also very importantSecond, national interests are also realized in every scientific investigation, for example, the investigation of the geographical environment is to analyze whether there are some natural resources underground. After all, European and American countries have already started relevant investigations, and although Antarctica does not belong to anyone or any country, it does have its own sphere of influence, which is ironic, right? Moreover, this kind of game is also played by these countries, so in the future, we must not lag behind our country's possible national interests in the future to participate in scientific surveys in Antarctica.

Third, the country's macro configuration and forward-looking scientific investigation of Antarctica is the 37th, although China's research on Antarctica started late, but with the progress of our science and economy, Antarctica's scientific research work has been carried out steadily, which also reflects our country's forward-looking and macro resource allocation, scientific research is not easy, and it is expected that our scientists will be able to discover scientific achievements in Antarctica in the future. <>

China's 37th Antarctic expedition team set off from Shanghai to Antarctica on November 10, 2020, successfully completed the material supply and personnel rotation tasks of the Antarctic Great Wall Station and Zhongshan Station, carried out a comprehensive survey of the Southern Ocean ecosystem and marine environment, successfully improved the environmental monitoring buoy in the westerly wind belt, and achieved a number of scientific research results.

First, the significance of scientific investigation lies in the study of the scientific information collected, second, national interests are also important because there are many natural resources, and third, the macro allocation of the country and forward-looking.

In the course of this expedition, the rescue operation of the international Antarctic expedition team members was also successfully carried out, and the international cooperation on the supply of Antarctic expedition materials was carried out. At the same time, it has withstood the test of the new crown pneumonia epidemic to ensure that all members of the expedition team have "zero infection".

1.In response to global climate change and other issues, carry out scientific investigations in hydrometeorology and ecological environment, 2Carry out operational monitoring of some new pollutants.

3.Carry out the rotation of winter personnel and material supply at Zhongshan Station and Great Wall Station in Antarctica.

The main content of scientific expeditions is the investigation of the natural environment, and due to the geographical location of Antarctica, it has an important impact on the study of global climate change.

The main task of scientific expeditions is to go to Antarctica and other uninhabited areas to discover treasures, explore the available resources underground, and better benefit the country and people.

In November 1984, China sent its first national Antarctic expedition team, and in February 1985, China's first Antarctic research base, the Great Wall Station, was built on King George Island. In November 1988, China's first East Antarctic expedition team embarked on its journey, and in February of the following year, China's second Antarctic research base was built on the Lasman Hills in East Antarctica, Zhongshan Station. As of March 2002, China had successfully organized 19 Antarctic scientific expeditions, with about 3,000 people visiting the polar regions.

The seasons in the northern and southern hemispheres are opposite, November to March of the following year is the winter of the northern hemisphere, and the summer of the southern hemisphere, when the temperature in the Antarctic region is high, it is advisable to have a polar daylight phenomenon, which is convenient for scientific investigation

Therefore, d

On the day, China's first Antarctic scientific expedition team arrived on Enksburg Island by the "Snow Dragon", and then carried out the first stage of unloading work, and lifted more than tons of equipment and materials for construction to the new station area, including containers for multiple purposes, such as scientific research work cabins, accommodation cabins, living cabins, power generation cabins, spare parts cabins, etc.

Because the "Snow Dragon" arrived on Enksburg Island for the first time earlier than before, it was blocked by more than one meter of ice near the shore, so it was unable to carry out the landing of small boats on the beach at that time, and it was not possible to transport large construction machinery and equipment to the island.

According to reports, Enksburg Island, also known as the "unspeakable island," is located in the waters of the Ross Sea in Antarctica, near east longitude and south latitude. The topography of Enksburg Island is high in the west and low in the east, with a north-south mountain beam on the west side, flat and hilly land on the east side, and a freshwater lake that accumulates water all year round.

According to the plan, China's first Antarctic expedition team will make preliminary preparations for the construction of China's fifth Antarctic research station and the third perennial scientific research station after the Great Wall Station and Zhongshan Station on Enksburg Island.

Answer B In December, the direct point of the sun is close to the Tropic of Capricorn, and most of Antarctica enters the polar day period, which is also the "warm period" of the region, with high temperatures and good light conditions, which is conducive to scientific investigations.
