Sea ice and NDVI variability in W- & E-Sb. (a) Map of the Svalbard Archipelago depicting mean sea ice concentration for the period 2000–2014 and the extent of W-Sb & E-Sb. Eight-day mean sea ice concentration and NDVI values are shown for E-Sb (b,c) and W-Sb (d,e) for each year from 2000 to 2014 during the period of the year for which good quality data is available (Day-of-Year, DOY 113 – April 23 to DOY 273 – September 30). The growing season (defined here as DOY 161 to DOY 249 – see Methods) is highlighted as a green box. Note the larger inter-annual variability in the early growing season starting date and phenology as seen in the NDVI values in E-Sb, and the overall larger sea ice concentration in E-Sb during the early and peak of the growing season, which reaches similar values to those in W-Sb in the late growing season only (~DOY 209) onwards.
