This study measures b-vitamins and cobalamin in the Northwest Atlantic over 5 years, showing seasonal differences in their concentrations and their impact on phytoplankton growth.

This paper shows a diatom produces the cobalamin lower ligand, α-ribazole, under cobalamin-deplete conditions, suggesting eukaryotic contributions to cobalamin remodeling in marine ecosystems.

This study measures pseudocobalamin and methionine synthase in Synechococcus cultures and communities, showing consistent pseudocobalamin quotas in the Northwest Atlantic Ocean.
