This dataset provides annual movies created from daily and twice daily images of (1) vegetation stands across the S1 Bog showing the seasonal changes of vegetation and appearance and disappearance of snow and (2) vegetation inside the SPRUCE experimental chambers and ambient unchambered plots showing the effects of experimental warming and elevated carbon dioxide (CO2) treatments both at the whole plot level and focus on a close-up on part of the shrub layer within each plot. Movies are provided from June 2010 through December 2022 (2010-06-10 to 2022-12-31). The data set is expected to be appended with additional yearly input. This data set contains 184 video files in *.m4v, *.mp4, or *.mov format.
These movies cover both pre-treatment and current treatments of whole ecosystem warming and elevated carbon dioxide (CO2) treatments associated with the SPRUCE (Spruce and Peatland Responses Under Climatic and Environmental Change) experiment. There are ten experimental plots with chambers receiving five temperature treatments (+0, +2.25, +4.5, +6.75, +9°C) at ambient CO2, and the same five temperature treatments at elevated CO2 (+500 ppm). Movies for two unchambers ambient plots are included. Compiled movies are useful for examining the phenology of the bog, the changes to the landscape as experimental facilities were constructed, and the effects of warming and elevated CO2 within treatment plots.
User Note: Starting in 2017, Phenocam videos began being published annually in the SPRUCE Vegetation Phenology in Experimental Plots from Phenocam Imagery datasets. Please see SPRUCE Vegetation Phenology in Experimental Plots from Phenocam Imagery, 2015-2022 for a full list of these datasets.
