Data sets

Neogloboquadrina pachyderma compiled data from vertical profiles in the Arctic Ocean Franziska Tell https://doi.pangaea.de/10.1594/PANGAEA.941250

Short summary

This study analyses the production of calcite shells formed by one of the main Arctic pelagic calcifiers, the foraminifera N. pachyderma. Using vertically resolved profiles of shell concentration, size and weight, we show that calcification occurs throughout the upper 300 m with an average production flux below the calcification zone of 8 mg CaCO₃ m⁻² d⁻¹ representing 23 % of the total pelagic biogenic carbonate production. The production flux is attenuated in the twilight zone by dissolution.
