Abstract:
The present dataset contains measurements of vertical particle fluxes (export) and their elemental composition. Data was collected with sediment traps in several in situ mesocosm experiments on ocean acidification. Study locations were the Kongsfjord in Svalbard (2010), the Raunefjord in Norway (2011), Storfjärden in Finland (2012), the Gullmar Fjord in Sweden (2013), and Gando Bay in Gran Canaria, Spain (2014). The dataset was to investigate the impact of ocean acidification on vertical particle fluxes and their elemental composition (stoichiometry of Si, C, and N).
