Reduced marine phytoplankton sulphur emissions in the Southern Ocean during the past seven glacials

Ice core derived marine biogenic sulphate does not agree with marine sediment records. Here based on new ice core records spanning the past 720,000 years obtained from Dome Fuji the authors propose that dust contributed a higher percentage of sulphate aerosols than previously thought.
