SPRUCE: S1-Bog and Experimental Plot Phenology Movies, Marcell Experimental Forest, Minnesota, 2010-2025

Description

This dataset provides annual movies created from daily and twice daily images from the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experimental site within the Marcell Experimental Forest in northern Minnesota, USA. Images were collected from (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 2025 (2010-06-10 to 2025-12-31). 

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.

Each of the provided files is a movie of compiled daily photos for the respective timeframe and camera view. This dataset contains 268 video files in *.mp4 format. Additional metadata are provided: a file-level metadata file in comma-separate values (.csv) format and a user guide in PDF (*.pdf) format. In the September 2026 update to this dataset, the title was updated from ‘SPRUCE S1-Bog Phenology Movies, Beginning in 2010’ to ‘SPRUCE: S1-Bog and Experimental Plot Phenology Movies, Marcell Experimental Forest, Minnesota, 2010-2025’ and 12 videos in *.m4v format from 2010-2014 and 28 videos in *.mov format from 2018 were converted to *.mp4 format.
