Once the ice core is out of the borehole, it is pushed out using a piston (rod) while maintaining the core's orientation. 

Next, it is wiped with a cloth to remove the ethisol (drilling liquid).

Then it is assembled with a small piece of the previous core to maintain the core's rotation for physical analyses. Using the vertical saw, it is cut every meter, and a photo is taken of each piece. A TAG is added with the date, depth, length, and core number.

Finally, the core is transported to the “Cave” or the “Science trench” where the handling will continue.

The reason we have solstices, polar circles, and seasons is due to a single fundamental factor: the Earth's axial tilt. The solstices are the precise moments in the Earth's orbit when the axis tilt reaches its maximum orientation towards or away from the Sun.

Within the polar circles, the following are observed at least once a year: 

• The midnight sun (the sun does not set)
• The polar night (the sun does not rise)

December 21^st is the winter solstice in the Northern Hemisphere:

• The shortest day of the year
• The longest night

In the Southern Hemisphere, it is the opposite: the summer solstice

• The longest day
• The shortest night of the year

"In Iran, we celebrate Yalda (which means “birth,” celebrates the victory of light over darkness), the longest night, with family and recite poems..."

The good news has arrived: the days of sorrow will not last. What once was will not remain, and what is now will not remain either.
