Practical Information


The European Physical Society has declared the Niels Bohr Institute as a Historical Site with great international importance for developments in physics and research. The Niels Bohr Institute in Copenhagen was established in 1921 for the physicist and Nobel laureate, Niels Bohr, who in 1913 created the groundbreaking atomic model that formed the basis for our understanding of how the world is constructed, and later as the basis for quantum  mechanics, which has revolutionised technological development.

The Physics of Ice and Climate group is a division of the Niels Bohr Institute, University of Copenhagen. The main activities of the group are drilling and analysis of ice cores with the objective of understanding climate change in the past in order to improve our understanding of present and future climate change.

The group has led the international drilling projects GRIP, NGRIP, NEEM, ReCAP and EGRIP that have led to comprehensive investigations into the climate of the past 128,000 years, corresponding to the most recent glacial-interglacial cycle. We also drill ice cores in the Antarctic in cooperation with our partners and we are part of EPICA-oldest Ice.
By performing measurements on the ice cores, we have the opportunity to study how climate has changed, and by measuring the air confined in the small bubbles of the ice, we reveal changes in the composition of the past atmosphere. We use data from ice core drillings as well as from radar observations to examine the ice sheet’s anatomy and flow pattern, and by counting annual layers in the ice sheet we can precisely date the ice.


As Copenhagen offers a variety of hotels, hostels and airBnB’s in various price classes, we suggest ICAT attendees organise their own housing according to their individual priorities. However to give an idea of the prices, below are some options in different price classes:

The Metro station is located at the end of Terminal 3 and is covered by the roof of the terminal.

Tickets for the Metro are available at the Metro station and at the DSB ticket sales counter in Terminal 3.
