Lisätietoa:Report 1 (I) Content 1. Air temperatures at the Kevo Station, Utsjoki, in the River Tana /Teno watershed 2. Air temperatures are reflecting obviously into the running water temperatures 3. Diurnal temperature synchrony between temperature in air, in large rivers and in small brooks in the River Tana watershed 4. Water temperatures in the spawning ground of salmon from egg fertilization in October to the end of the first year as 0+ -old juvenile (yearling) 5. Snow cover indicates the length of cold winter period 6. Precipitation measured from the snow and rain is important for discharge in rivers 7. Changes in flow and water level can indicate climate changes and therefore disturb salmon migrations and salmon fishery 8. Ice breaking- up date and freezing (=ice formation) on the way to change in long-term and affect to the catch timing of salmon in the river Tana watershed
