Journal ArticleDOI
Ice sheets as a significant source of highly reactive nanoparticulate iron to the oceans
Jon R. Hawkings,Jemma L. Wadham,Martyn Tranter,Robert Raiswell,Liane G. Benning,Peter J. Statham,Peter J. Statham,Peter J. Statham,Andrew J. Tedstone,Peter Nienow,Katherine Lee,Jon Telling +11 more
TL;DR: Estimates of labile iron fluxes in meltwater are comparable with aeolian dust fluxes to the oceans surrounding Greenland and Antarctica, and are similarly expected to increase in a warming climate with enhanced melting.
Journal ArticleDOI
The Greenland Ice Sheet as a hot spot of phosphorus weathering and export in the Arctic
Jon R. Hawkings,Jemma L. Wadham,Martyn Tranter,Jon Telling,Elizabeth Bagshaw,Alexander Beaton,Sarah-Louise Simmons,David M Chandler,Andrew J. Tedstone,Peter Nienow +9 more
TL;DR: The contribution of ice sheets to the global biogeochemical cycle of phosphorus is largely unknown, due to the lack of field data as mentioned in this paper, but the results indicate that the ice sheet is a hot spot of phosphorus export in the Arctic.
Journal ArticleDOI
The effect of warming climate on nutrient and solute export from the Greenland Ice Sheet
Jon R. Hawkings,Jemma L. Wadham,Martyn Tranter,Emily Lawson,Andrew Sole,Tom Cowton,Andrew J. Tedstone,I. D. Bartholomew,Peter Nienow,David M Chandler,Jon Telling +10 more
TL;DR: In this paper, the authors present four years of hydrological and geochemical data from a large Greenland Ice Sheet catchment that includes the two highest melt years on record (2010, 2012).
Journal ArticleDOI
Reviews and syntheses: The biogeochemical cycle of silicon in the modern ocean
Paul Tréguer,Jill N. Sutton,Mark A. Brzezinski,Matthew A. Charette,Tim DeVries,Stephanie Dutkiewicz,Claudia Ehlert,Jon R. Hawkings,Aude Leynaert,Sumei Liu,Natalia Llopis Monferrer,María López-Acosta,Manuel Maldonado,Shaily Rahman,Lihua Ran,Olivier Rouxel +15 more
TL;DR: In this article, the authors show that recent advances in process studies indicate that total Si inputs and outputs, to and from the world ocean, are 57'% and 37'% higher, respectively, than previous estimates.
Journal ArticleDOI
Potentially bioavailable iron delivery by iceberg-hosted sediments and atmospheric dust to the polar oceans

TL;DR: In this article, a suite of more than 50 iceberg-hosted sediments contain a mean content of 0.076% Fe as ferrihydrite, which produces iceberghosted Fe fluxes ranging from 0.7 to 5.5 and 3.2 to 25.2% to the Arctic and Southern oceans respectively.
