INSUBCONTINENT EXCLUSIVE:
Chinas 41st Antarctic exploration has actually successfully completed a critical survey of the Amundsen Sea and Ross Sea, discovering
uncommon circumstances of polynyas
These are essential open-water regions within sea ice that influence both Antarcticas ecology and worldwide climate patterns.Sun Yongming, a
member of Chinas 41st Antarctic expedition, described the visualization of sea ice concentrations and the significance of polynyas along the
This map reveals the typical sea ice concentration from 2013 to 2020
It shows data for November, with yellow areas indicating 100 percent ice coverage and pure blue areas representing 0 percent, or open water
Along the coast, you can see the blue water surface, which we call polynyas, stated Sun.Polynyas form through different natural processes
Sun described that the most common technique includes Antarcticas katabatic winds & strong, down winds that push newly formed sea ice away
from the coast, developing open water areas
This phenomenon, known as a wind-driven polynya, fluctuates in size in time, depending on changing weather patterns
In very low temperature levels, its only these polynyas that produce brand-new ice
Once brand-new ice forms, it gets blown outside by the wind, and more ice continues to form, so we describe this procedure as an ice factory
We generally determine a polynyas size by the quantity of ice it produces
The Amundsen Sea polynya is currently the fourth biggest amongst all the polynyas around Antarctica; its rather substantial, Sun added.More
than a lots big polynyas exist around Antarctica, with the Amundsen Sea polynya being among the largest and most significant
These areas play a crucial function in the areas heat exchange, supporting higher biological productivity and offering distinct insights
into the dynamics of Antarcticas environment
Polynyas facilitate heat exchange, which creates a more favorable environment for biological activity
Research studies show that the Amundsen Sea polynya has the greatest primary performance of all the polynyas around Antarctica
Thats why were particularly focused on comprehending how polynyas impact the entire ecosystem, which is why weve been carrying out extensive
ecological observations in the area, Sun concluded.Chinas 41st Antarctic Expedition set sail from the southern Chinese port city of
Guangzhou on November 1, 2024, with three vessels: the Xuelong and Xuelong-2 for clinical research study and logistics, and the Yongsheng
cargo ship, which is supplying materials for the Qinling Station
The objective is set to last nearly 7 months, with a return set up for May 2025.
