Résumé :	Phytoplankton pigments in sediment cores from four New Zealand fjords were quantified to investigate community composition and primary production in this pristine and remote region. Downcore sediment records from Doubtful Sound, Fiordland, were also compared with phytoplankton pigments in sediment traps to investigate pathways of phytodetritus flux from the upper water column to the sediment. Historic primary production was estimated using downcore chlorophyll a (Chl a) and beta-carotene as proxies for total algal biomass. Sedimentary Chl a was similar across Fiordland (p=0.09), but beta-carotene was significantly different in Broughton Arm (Kruskal-Wallis p
