Retreat of large marine-terminating glaciers may increase iron supply to surface waters
The findings demonstrate that glacial retreat and loss of ice-shelves may potentially result in increases in dissolved iron supply to surface waters downstream of large marine terminating glaciers in future.

Manganese: a surprising co-limiting factor of phytoplankton growth in the Southern Ocean
One of the main consequences of this work is that manganese should be included in ocean-climate models, more particularly to improve the accuracy of their predictions in this area.
