  • Bird Report for the Varanger Peninsula 7-13 March 2013
    Bird report for the Varanger Peninsula, Norway, 7-13 March 2013 Authors: Gitte Kruse Allan Kruse Aoi Bringsøe Henrik Bringsøe – DOF Køge (Danish Ornithological Society, Køge regional group) Photos: Henrik Bringsøe Introduction We had three main reasons for going to the Varanger Peninsula in the far north-east of Norway in March 2013. We wished to see the: King Eider Steller’s Eider Northern lights (or aurora borealis) The two ducks and several other species will winter at Varanger which is always ice-free because of the warm water moves of the Gulf Stream. The ice-free conditions attract ducks from Siberia and other north-eastern areas to spend the winter there. For our journey we chose a period of the very early phase of the new moon (7%). The moon was only visible at daytime which meant that the nights were as dark as possible. As it was close to the equinox, the days were not too short (sunrise at 5:50, sunset at 16:35). Other bird groups were also given high priority, i.e. gulls, eagles and tits. Had we made our journey in April it would not have been possible to see King Eider although there would be less snow in April and it would be easier to get around. Gitte and Allan were responsible for the overall travel plans as they had visited Varanger in June 2010 and gained valuable experience. They booked accommodation at Mr. Øyvind Artnzen in Vadsø in September 2012 and bought flight tickets to Kirkenes. For their homeward journey they chose the coastal service Hurtigruten from Kirkenes to Tromsø and then a flight to Copenhagen.

  • The Expert Mechanism on the Rights of Indigenous Peoples (EMRIP)
    The Expert Mechanism on the Rights of Indigenous Peoples (EMRIP) Your ref Our ref Date 18/2098-13 27 February 2019 The Expert Mechanism on the Rights of Indigenous Peoples (EMRIP) – Norway's contribution to the report focusing on recognition, reparation and reconciliation With reference to the letter of 20th November 2018 from the Office of the United Nations High Commissioner for Human Rights where we were invited to contribute to the report of the Expert Mechanism on recognition, reparation and reconciliation initiatives in the last 10 years. Development of the Norwegian Sami policy For centuries, the goal of Norwegian Sami policy was to assimilate the Sami into the Norwegian population. For instance Sami language was banned in schools. In 1997 the King, on behalf of the Norwegian Government, gave an official apology to the Sami people for the unjust treatment and assimilation policies. The Sami policy in Norway today is based on the recognition that the state of Norway was established on the territory of two peoples – the Norwegians and the Sami – and that both these peoples have the same right to develop their culture and language. Legislation and programmes have been established to strengthen Sami languages, culture, industries and society. As examples we will highlight the establishment of the Sámediggi (the Sami parliament in Norway) in 1989, the Procedures for Consultations between the State Authorities and Sámediggi of 11 May 2005 and the Sami Act. More information about these policies can be found in Norway's reports on the implementation of the ILO Convention No. 169 and relevant UN Conventions.

  • Diagenesis and Weathering of Quartzite at the Palaeic Surface on the Varanger Peninsula, Northern Norway
    NORWEGIAN JOURNAL OF GEOLOGY Diagenesis and weathering of quartzite at the Paleic surface 239 Diagenesis and weathering of quartzite at the palaeic surface on the Varanger Peninsula, northern Norway Jakob Fjellanger & Johan Petter Nystuen Fjellanger, J. & Nystuen, J. P. Weathering of quartzite at the palaeic surface on the Varanger Peninsula, northern Norway. Norwegian Journal of Geology, Vol. 87, pp. 133-145.Trondheim 2007. ISSN 029-196X. Weathered zones in quartzitic bedrock on the Hak alancˇearru Mountain on the Varanger Peninsula, northern Norway, have been examined, as has the timing of their development. The weathered zones are mainly associated with fractures formed by tectonic shear. SEM, microprobe and thin section studies reveal features belonging to the diagenesis and weathering history of the rock. Flakes of phyllosilicate minerals were originally depo- sited together with the quartz sand and became attached as coatings to the surface of individual quartz grains as well as forming an intergranular fill. Some of the detrital clay minerals turned into kaolinite during an early stage of the burial diagenesis. Kaolinite was later partly transformed to dickite. Quartz dissolution with concomitant quartz cementation and illite formation took place during later burial diagenesis. The kaolinite occurs in intergranular voids where it was partly transformed to pyrophyllite at a peak temperature of about 300 ˚C. As the overlying rocks were eroded the previously formed tectonic joints and small faults enhanced the circulation of ground water. This facilitated chemical weathering along joints and nearby grain contacts where slight dissolution of quartz significantly weakened inter-granular bonds. The resulting increase in permeability facilita- ted recent disintegration of the quartzite by mechanical processes.
