Sejong Science Station, Korea's first Antarctic science station, is located on Barton Peninsula, King George Island, in the north of Antarctica.
Established in 1988, the 37th winter research group is in operation this year.
If you walk 2km from Sejong Science Base, there is a breeding ground for penguins on a coastal hill.
In 2009, thanks to the efforts of our researchers, this place was designated as an Antarctic special protection area and is called Penguin Village.
Penguin Village is divided into left and right breeding areas for gentoo penguins and chinstrap penguins.
Somewhere, the cries of penguins are loud.
A war with seagulls that fly in for baby penguins.
In the Antarctic environment where food is not abundant, Antarctic gulls steal the eggs and chicks of other birds to survive.
The bird research team led by Dr. Kim Jeong-hoon as the lead researcher visits penguin breeding grounds every year.
Check whether there is any change in the penguin population and what their growth and feeding status are.
This data becomes important data for reading changes in the Antarctic ecosystem.
There are high peaks on the hill behind Sejong Science Base.
Our research team gave names to these peaks.
The names include Baekdu Peak, Silla Peak, Baekje Peak, Goguryeo Peak, and Balhae Peak.
The highest peak here is Baekdu Peak! Dr. Hong Soon-gyu, who studies lichens, is moving here.
Unlike plants rooted in the ground, lichens are only exposed to the surface layer.
Therefore, in order to continue to defend against changes in the natural environment, many secondary metabolites are produced.
It serves as a clue to confirm and predict climate change.
Centered around the Sejong Science Base, there are Penguin Village and Porter Bay to the southwest, Baekdubong Peak to the south, and Marian Bay to the east.
The research vessel Sejong 1 is sailing in Marian So Bay with Dr. Eunjin Yang's team conducting oceanographic research.
Move to a designated point for seawater collection.
In order to check the physical characteristics from the surface to the bottom at each point, seawater is continuously collected by repeatedly lowering and raising a measuring instrument with a sensor.
The ice wall of Marianso Bay is retreating significantly compared to the past.
As fresh water from melted glaciers mixes with the sea, changes in oxygen concentration and phytoplankton occur.
Phytoplankton is the main food source for krill, which plays the most important role in the Antarctic Ocean ecosystem.
Krill is a food source not only for penguins but also for other animals in the Antarctic Ocean.
According to Kim Hyeon-cheol, director of the Polar Research Institute's Remote Sensing Cryoosphere Information Center, half of Marian Soman's glaciers have retreated since 1956, when the data was created. In the case of Porterso Bay, it is reported that a large amount of glaciers have retreated since 1989.
A flock of seagulls is noisy on the coast in front of the Sejong base.
The bodies of dead krill are filled among the finely broken ice floes.
It unexpectedly became a gathering place for Antarctic gulls.
As the nearby ice wall collapsed, the suspended glacial material melted into the sea.
Doctors say that this is the result of krill, which must eat plankton, starving to death while ingesting these floating substances.
Antarctica is changing rapidly. In a place where people are not easily allowed to visit, our researchers are conducting research as actively as in any other country, and the results are also remarkable. But a fundamental question! Why do we need to study that distant land, the poles?
A consistent story of scientists visiting Antarctica.
When air gets hot, it rises and circulates as it comes down to the cold South and North Poles due to atmospheric pressure. The Earth's air moves due to the poles. The same goes for water. Tropical water flows south through the surface of the water, and Antarctic water flows deep into the tropics. Ultimately, the world is connected to the poles.
Changes in the polar regions, the fundamental location of climate change, allow us to predict and prepare for the climate of this land where we live. So they go to Antarctica.
