Caption

Study area and surface air temperature trends. (A) Map of Svalbard archipelago in the arctic North Atlantic, with location of Mosselbukta study site in northern Spitsbergen (rectangle, enlarged in B), where long-lived encrusting coralline algal buildups were collected in June 2016. Red arrow indicates approximate path of West Spitsbergen Current (WSC). (B) Detailed shaded-relief map of study site with sampling location Ellingsenodden in Mosselbukta (red asterisk). Source of shaded-relief map: https://toposvalbard.npolar.no/. (C) Global winter surface-air temperature trends since C.E. 1980 (linear trends in °C/decade for December-February). Geographic locations of the Svalbard archipelago (this study, white open circle), Newfoundland, Canada (Hill and Jones [1990] sea-ice record, blue circle), and Labrador-Canadian Arctic (Halfar et al. [2013] algal sea-ice proxy, black circle) are shown. Data source: http://data.giss.nasa.gov/gistemp.
