Can You Feel the Harsh Climate of the High Arctic? Photographed in Svalbard, Norway. Shrub ring-growth is irregular thanks to the high-arctic Svalbard climate. The story behind this photo started on a sailboat at the northern distribution margin of shrubs. Months in the laboratory generated 2mm cross-sections of Salix polaris (polar willow). Art became science, developing a ring-growth time-series retrospectively tracking vascular plants’ biomass.
