Trace metals are required for numerous processes in phytoplankton and can influence the
growth and structure of natural phytoplankton communities. The metal contents of …

Since the mid-1980s, our understanding of nutrient limitation of oceanic primary production
has radically changed. Mesoscale iron addition experiments (FeAXs) have unequivocally …

Baleen whales influence their ecosystems through immense prey consumption and nutrient
