During the RV Meteor cruise 21 to the Northeast Atlantic Ocean, from March to May 1992, planktic foraminifera were sampled using a multiple opening-closing net. While sampling, two storms with wind forces up to 12 Beaufort caused intensified surface layer mixing with shifts in the depth of the upper ocean mixed-layer from 20-40 m to 170-240 m. The standing stock of living foraminifera and export of empty tests from the productive zone increased after the storms, leading to pulses of CaCO 3 exported from the surface to deep water.
