Short summary
We present the first Fe record from the NEEM ice core, which provides insight into past atmospheric Fe deposition in the Arctic. Considering the biological relevance of Fe, we questioned if the increased eolian Fe supply during glacial periods could explain the marine productivity variability in the Fe-limited subarctic Pacific Ocean. We found no overwhelming evidence that eolian Fe fertilization triggered any phytoplankton blooms, likely because other factors play a more relevant role.
