Our Word of the Year choice serves as a symbol of each year’s most meaningful events and lookup trends.
It is an opportunity for us to reflect on the language and ideas that represented each year.
Ice cores have been studied since the early 20th century, and several cores were drilled as a result of the International Geophysical Year (1957–1958).
Depths of over 400 m were reached, a record which was extended in the 1960s to 2164 m at Byrd Station in Antarctica.
Numerous other deep cores in the Antarctic have been completed over the years, including the West Antarctic Ice Sheet project, and cores managed by the British Antarctic Survey and the International Trans-Antarctic Scientific Expedition.Ice is lost at the edges of the glacier to icebergs, or to summer melting, and the overall shape of the glacier does not change much with time.Impurities in the ice provide information on the environment from when they were deposited.It also implies that Satya/Truth exists in all Yugas.The charaṇas are divided as follows: × 50 = 155.52 trillion years (50 years of Brahma) (6 × 71 × 4320000) 7 × 1.728 × 10^6 = 1852416000 years elapsed in first six Manvataras, and Sandhi Kalas in the current Kalpa 27 × 4320000 = 116640000 years elapsed in first 27 Mahayugas of the current Manvantara 1.728 × 10^6 1.296 × 10^6 864000 = 3888000 years elapsed in current Mahayuga 3102 2017 = 5119 years elapsed in current Kaliyuga.
