Iron supplied by glacial weathering results in pronounced hotspots of biological production in an otherwise iron-limited Southern Ocean Ecosystem. However, glacial iron inputs are thought to be dominated by icebergs. Here we show that surface runoff from three island groups of the maritime Antarctic exports more filterable (<0.45 μm) iron (6-81 kg km<sup>-2</sup> a<sup>-1</sup>) than icebergs (0.0-1.2 kg km<sup>-2</sup> a<sup>-1</sup>). Glacier-fed streams also export more acid-soluble iron (27. ...[more]
