Snow Dragon 2 has achieved a small goal! What else does it need to do next? Project | Arctic Ocean | Objectives

With the ocean optical survey at the 10th station

Completed on the midship deck of the "Snow Dragon 2" polar scientific research icebreaker ship

The 13th Scientific Expedition to the Arctic Ocean in China

Generate the first fully completed homework project

The ocean optical observation project belongs to the category of oceanic scientific research assignments

A total of 10 observation stations will be arranged for this scientific examination

Utilizing professional examination equipment

Detecting solar irradiance at different depths in the ocean

Used to measure the absorption and attenuation process of solar radiation energy in the ocean

Chukchi Sea: abundant floating ice and heavy sea fog

After entering the Arctic Circle

The Snow Dragon 2 encountered more and more floating ice

Low outdoor temperature and poor visibility

The safe speed of the Xuelong 2

Controlled within 8 to 9 knots

Compared to the previous Arctic scientific expedition

The route within the Arctic Circle this time has a lot of floating ice and heavy sea fog

Objectively increasing the difficulty of related assignments

The most interesting mission of "Snow Dragon 2"

Open blind box

△ Sea anemone, a type of coelenterate.

——CTD

When doing homework

Open the side door and lower the CTD

Collect seawater samples at different depths

Create conditions for subsequent research

Why explore the Arctic Ocean less frequently?

The first polar bear encountered by the Snow Dragon 2 during this voyage. Click on the image to watch the complete video.

China has explored Antarctica 39 times

Exploring the Arctic Ocean only 12 times

Mainly due to the short navigation time and limited navigation data in the Arctic Ocean

The Arctic Ocean surface freezes over the years

The time when the ship can sail normally

There are only two or three months in a year

In addition, this water area has always lacked accurate and reliable navigation data

And there is a large amount of floating ice and icebergs

Bringing huge challenges to ship navigation

On July 25, 2023, a Chinese scientific expedition team member worked at the Chinese Arctic Yellow River Station in Novo Olesson, Svalbard Islands, Norway.

1999

China's first scientific expedition to the Arctic Ocean

July 28, 2004

The first Arctic scientific expedition station in China

——Establishment of China Arctic Yellow River Station

Created an important research platform for China in the Arctic region

It is understood that this scientific expedition

We will conduct atmospheric and marine environmental surveys

Investigation projects such as biological resource investigation and pollutant monitoring

We will also conduct a comprehensive sea ice survey in the ice zone at an appropriate time

According to the schedule

Oceanic scientific research assignments in the Chukchi Sea area

It will end in mid August

Looking forward to more good news from "Xuelong 2"

New comment: Donkey like "morale" limit pulls US debt "bomb" fuse hard to dismantle US | debt | morale

On the evening of June 1st, the US Senate passed a bill on the federal government's debt ceiling and budget, and the flame of the US debt bomb was temporarily extinguished at the last moment. The two parties in the United States have staged an extreme tug of war over the US debt bomb. Some experts believe that the US debt crisis is the result of the reckless politics promoted by the US dollar hegemony, and the underlying cause of this crisis is the highly polarized political system of the US. Since the end of World War II, the US Congress has adjusted the debt ceiling more than a hundred times. The recurring debt crisis will not only have a catastrophic impact on the US economy and people's livelihoods, but also continuously erode the value of US dollar assets such as government credit and US bonds, bringing significant and far-reaching impacts to the global economic landscape. 【
