Resistance of an Arctic phytoplankton assemblages to ocean acidification and high irradiance, link to supplement in MS Excel format ...

The Arctic Ocean is a region particularly prone to on-going ocean acidification (OA) and climate-driven changes. The influence of these changes on Arctic phytoplankton assemblages, however, remains poorly understood. In order to understand how OA and enhanced irradiances (e.g. resulting from sea-ice...

Description
Summary:The Arctic Ocean is a region particularly prone to on-going ocean acidification (OA) and climate-driven changes. The influence of these changes on Arctic phytoplankton assemblages, however, remains poorly understood. In order to understand how OA and enhanced irradiances (e.g. resulting from sea-ice retreat) will alter the species composition, primary production and ecophysiology of Arctic phytoplankton, we conducted an incubation experiment to investigate the effects of OA and enhanced irradiance levels on an assemblage from Baffin Bay (71°N, 68°W). Seawater was collected from just below the deep Chl a maximum, and the resident phytoplankton were exposed to 380 and 1000 µatm pCO2 at both 15% and 35% incident irradiance. On-deck incubations, in which temperatures were 6°C above in situ conditions, were monitored for phytoplankton growth, biomass stoichiometry, net primary production, photo-physiology and taxonomic composition. During the 8-day experiment, taxonomic diversity decreased and the diatom ... : Supplement to: Hoppe, Clara Jule Marie; Schuback, Nina; Semeniuk, David M; Giesbrecht, Karina E; Mol, Jacoba; Thomas, H; Maldonado, Maria T; Rost, Björn; Varela, Diana E; Tortell, Philippe Daniel (2018): Resistance of Arctic phytoplankton to ocean acidification and enhanced irradiance.
