Description
Summary:•We report in situ observations during an autumn storm in the northeast Atlantic Ocean.•Surface chlorophyll increased due to the redistribution of a subsurface chlorophyll maximum.•Nanoplankton dominated the phytoplankton community pre- and post-storm.•The picoplankton proportion increased 4-fold as the storm developed but the increase was short lived.•Microplankton peaked coincident with maximum surface chlorophyll concentrations. Phytoplankton chemotaxonomic distributions are examined in conjunction with taxon specific particulate biomass concentrations and phytoplankton abundances to investigate the biogeochemical consequences of the passage of an autumn storm in the northeast Atlantic Ocean. Chemotaxonomy indicated that the phytoplankton community was dominated by nanoplankton (2–20μm), which on average represented 75±8% of the community. Microplankton (20–200μm) and picoplankton (
