Telling who you are

We do not use badges for participants. In the beginning of each day students are asked to summarize in a 5-min presentation who they are and what their project is about. In this way we get to know each other quickly. The time limit is strict, so use no more than three illustrations (bring USB stick with pptx or pdf).


The excursion will be a trip to the area outside of Copenhagen. The trip is not difficult, but November in Copenhagen can get wet and cold. Good rain proof clothing and a sweater likely be necessary.

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 Centre for Ice and Climate is a Centre of excellence at the Niels Bohr Institute, University of Copenhagen. The main activities of the centre 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 Centre has led the international drilling projects GRIP, NGRIP, and NEEM 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 in 2015 we drilled through the Renland ice cap in East Greenland.

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.


We have not arranged for a joined housing for all ICAT students as Copenhagen offer a variety of hotels, hostels and airBnB’s in various price classes.

However to give you an idea of the rate, below are some options in different price classes: Ibsens Hotel (3 stars) and Kong Arthur (4 stars) (1400 dkr/night) are conveniently located by public transport from the airport close to Nørreport station. 

- (~850 dkr/night)Cabinn City is close to the main station Hovedbanegården and cheap.

- (~650 dkr/night) situated in Østerbro area offers single and double rooms, with private bath and breakfast served in your room. There is access to the kitchen. Further they offer small apartments.

- (~500 dkr/night) situated behind the main station (Hovedbanegården) is an affordable option although it can be a bit noisy.

How to get there

By air: Copenhagen airport is the nearest airport. From the airport you take the metro to Nørreport station and from there multiple buses go to the busstop Nørre Campus, just a few minutes walk from the institute (Juliane Maries vej 30, Copenhagen Ø).

Metro (airport) and tickets

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. Please note that the ticket machines do not accept notes, only coins and cards such as the Dankort, VISA, etc. When you get out of the gates from where luggage is picked up. Walk straight ahead and up the stairs, then continue straight ahead and you will get to the metro. However, before climbing the stairs on your right hand side there is a counter and machines where you can buy your public transportation ticket. You will need 3 zones (cost 36 dkr for a one way ticket). This will cover both the metro and the bus.

Nørreport station

At Nørreport station you get off the metro and change to eg. either bus 150 S, 6A, 42, 15E, 184 or 185.

By Train

You can get to Copenhagen central station by train. From there you can take a train to Nørreport (2 min) and continue with bus to busstop Nører Campus (see description for arriving with by air).

Transport within Copenhagen

The City Bike

is synonymous with Copenhagen and the only right way to get around in Copenhagen is biking. The City of Copenhagen has great bikes for rent. Special features like a tablet with built-in GPS makes it easy getting around. The City Bikes are available at various places within the city 24/7, 365 days a year. Each city bike has a touchscreen tablet used for navigation, payment and guiding to points of interest in Copenhagen and Frederiksberg.

More info on the bikes here:

To rent a bike, you need to create a user account. You can also create an account directly on the tablet.

Go to a docking station and take out a bike by entering your username and pin code on the bike’s tablet. Here you can see the number of available bikes and, if you like, you can book a bike in advance.

The bike has an electric motor and will assist you up to 22 km/h. A full battery should last you a couple of hours depending on your riding style.

You can return the bike to any of the docking stations in Copenhagen and Frederiksberg. The tablet will guide you to the nearest one.

The lock on the rear wheel enables you to park the bike anywhere during your trip. The hourly payment continues until the bike is safely returned to a docking station.

The price is DKK 25/hour with a regular user account, and DKK 6/hour with a monthly subscription (monthly fee DKK 70). The payment happens automatically once you have registered your credit card. See more about pricing here.
