Sea ice and primary production proxies in surface sediments from a High Arctic Greenland fjord : Spatial distribution and implications for palaeoenvironmental studies

In order to establish a baseline for proxy-based reconstructions for the Young Sound-Tyrolerfjord system (Northeast Greenland), we analysed the spatial distribution of primary production and sea ice proxies in surface sediments from the fjord, against monitoring data from the Greenland Ecosystem Mon...
