About this collection
This collection of papers brings together recent activities in marine biochemistry. This list was initially composed of articles published in a themed issue of Metallomics (6, 2014, guest edited by Rachel Austin) that highlighted emerging high-impact areas of research on metals in marine biochemistry. Since then, this collection has expanded and will continue to grow to include additional reports in this field, covering various aspects of this important area of metal biology. New articles will be added to this collection as they are published.
