The fertilising glacial ice

What is it about?

Glaciers and ice sheets are a major source of iron, which is potentially important in sustaining the high microbiological activity observed in the coastal regions near to land ice cover.

Why is it important?

Glaciers and ice sheets are potentially able to export iron that is available for biological uptake to downstream ecosystems, including seawaters. The findings provide evidence that Greenland Ice Sheet meltwaters may provide iron that may fuel the large summer phytoplankton bloom in the Labrador Sea. Phytoplankton are an important component of the marine food web and thus can sustain many other species up the food chain.
