Algal pigments in Hornsund (Svalbard) sediments as biomarkers of Arctic productivity and environmental conditions
Abstract Pigments (chloropigments-a and carotenoids) in sediments and macroalgae samples, collected in Hornsund, in July 2015 and July 2016, were analysed (HPLC) in this work. In spite of the aerobic conditions and the periodic intensive solar irradiation in the Arctic environment, neither of which...
