Climate change impact on primary production and phytoplankton taxonomy in Western Spitsbergen fjords based on pigments in sediments

Arctic climate changes are of global significance. This work investigates the influence of climate change on primary production and phytoplankton taxonomic composition in the western Spitsbergen fjords over the last century, using pigments in sediments. Nine sediment cores were analysed for chloropigment and carotenoid contents, and the five found to be richest in pigments were dated (210Pb, 137Cs) and analysed for additional parameters (Corg,...
