Heme b is an iron-containing co-factor in hemoproteins. Heme b concentrations are low (-1) in iron limited phytoplankton in cultures and in the field. Here, we determined heme b in marine particulate material (>0.7 μm) from the North Atlantic Ocean (GEOVIDE cruise – GEOTRACES section GA01), which...
