Abstract:
Datasets from Paulsen et al. (in prep) Emergent patterns between NDVI and plant biomass, summer temperature and tundra disturbance in a new time series from the high Arctic. Arctic Science. The datasets are part of the larger COAT vegetation monitoring in Svalbard (P.I. Virve Ravolainen).
Two datasets with biomass, summer temperature and disturbance, NDVI from drone and Sentinel-2 in plots (plot-level, 0.5 x 0.5 m) and within monitoring sites (site-level, 30 m diameter circle).
- loc/locality: Location of monitoring sites (adv=Adventdalen, bro=Brøggerhalvøya, sas=Sassendalen)
- site_id: the unique id of each monitoring site
- plot_id: the unique id of each plot within each monitoring site
- habitat: dry = dryas ridge habitat , mos = moss tundra habitat
- Drone NDVI (10 cm spatial resolution, NDVI captured with sequoia camera on fixed-wing eBeex drone)
- Sentinel-2 NDVI (10 m spatial resolution, Sentinel-2 L2A)
- Total biomass (total_biomass): total vascular plant biomass of main plant groups and species in grams per square meter
- Growing degree days (GDD): accumulated temperature above 1 degree C until ground sampling day for that monitoring site.
- Winter damage (winter_damage): Recordings of winter-damaged shrubs in plots on a scale from 1-8 (or mean per site).
- Biotic crust (biotic_crust): Recordings of biotic crust in plots on a scale from 1-12 (or mean per site).
- Goose grubbing (light_grubbing, severe_grubbing): Recordings of presence or absence of goose disturbance in plots (0=no goose grubbing, 1=light goose grubbing, 2=severe goose grubbing). On site-level it is the total number of plots for each category.
