Total oxygen uptake rates measured during POLARSTERN cruise PS94 (TransArcII)...

Total oxygen uptake rates were assessed by conducting sediment core incubations. After MUC retrieval and sediment core preparation on deck, three cores were taken to a dark,...

Annual degree day sums above 0°C calculated from daily averages obtained from hourly logging of soil surface temperature at every location. Freeze-thaw events calculated from...

(Table 3) Range of temperature extremes at the soil surface within and outsid...

Minimum and maximum temperatures are the extreme temperatures from hourly recordings for a single year. The time above maximum represents the period (in hours) when temperatures...

Values are calculated from monthly mean data (summer: December-February, autumn: March-May, winter June-August, spring: September-November).

(Table 1) Normalized difference vegetation index in control and warming plots...

Extreme winter warming events in the sub-Arctic have caused considerable vegetation damage due to rapid changes in temperature and loss of snow cover. The frequency of extreme...
