Comment:

Includes fluxes of planktonic and benthic foraminifera, the flux of foraminifera organic linings and % of agglutinated taxa. Relative abundance (%) of all taxa counted in the >63µm fraction after wet-sieving. Counting was done on wet samples, stored in buffering solution. Foraminifera species attributed to chilled Atlantic or Polar/Arctic groups can be found in Table 2 of the related paper.
