Prince Haakon of Norway, Princess Victoria of Sweden and Prince Frederik of Denmark, all heirs to the thrones in their countries, will take part in a research expedition to Greenland until June 1 during the official visit.
"The three of them have gone to Greenland for five days to study the effects of climate change," a spokeswoman for the Swedish royal court told AFP.
The three royals will travel with a group of internationally-renowned researchers to see the impact of global warming on Greenland and its people.
The trio will also take part in research seminars on climate change on board the ship HDMS Ejnar Mikkelsen, as it travels from Kangerlussuaq on the west coast to Disko Bay.
They will also visit the Ilulissat glacier, a UN heritage site on the west coast that has shrunk by over 15 kilometers in the space of a few years.
In May 2008, the three heirs to the throne made a similar trip to Norway's Arctic archipelago of Svalbard.
The announcement of the five day trip came on the same day as the Swedish royal court announced that Victoria's fiancé, Daniel Westling, had undergone kidney transplant surgery to correct a congenital condition that resulted in impaired renal function.
