K. Moore,Eva Ortega-Retuerta,Sharmila Pal,Chris Polashenski,Rick A. Reynolds,Brian D. Schieber,Heidi M. Sosik,Michael Stephens,James H. Swift +31 more
TL;DR: Evidence suggests that under-ice phytoplankton blooms may be more widespread over nutrient-rich Arctic continental shelves and that satellite-based estimates of annual primary production in these waters may be underestimated by up to 10-fold.
Journal ArticleDOI
Global distribution of atmospheric phosphorus sources, concentrations and deposition rates, and anthropogenic impacts
Natalie M. Mahowald,Tim Jickells,Alex R. Baker,Paulo Artaxo,Claudia R. Benitez-Nelson,Gilles Bergametti,Tami C. Bond,Ying Chen,David D. Cohen,Barak Herut,Nilgun Kubilay,Rémi Losno,Chao Luo,Willy Maenhaut,Kenneth A. McGee,Gregory S. Okin,Ronald L. Siefert,Seigen Tsukuda +17 more
TL;DR: A worldwide compilation of atmospheric total phosphorus (TP) and phosphate (PO4) concentration and deposition flux observations are combined with transport model simulations to derive the global distribution of concentrations and fluxes of TP and PO4.
Journal ArticleDOI
The biogeochemical cycling of phosphorus in marine systems
TL;DR: In this paper, a comprehensive review of the biogeochemical cycling of P within the oceans is given, with particular attention focused on the composition and recycling rates of P in the water column.
Journal ArticleDOI
Atmospheric Iron Deposition: Global Distribution, Variability, and Human Perturbations*
Natalie M. Mahowald,Sebastian Engelstaedter,Chao Luo,Andrea Sealy,Paulo Artaxo,Claudia R. Benitez-Nelson,Sophie Bonnet,Ying Chen,Patrick Y. Chuang,David D. Cohen,François Dulac,Barak Herut,Anne M. Johansen,Nilgun Kubilay,Rémi Losno,Willy Maenhaut,Adina Paytan,Joseph M. Prospero,Lindsey M. Shank,Ronald L. Siefert +19 more
TL;DR: The results imply that humans could be substantially impacting iron and bioavailable iron deposition to ocean regions, but there are large uncertainties in the authors' understanding.
Journal ArticleDOI
The Transcriptome and Proteome of the Diatom Thalassiosira pseudonana Reveal a Diverse Phosphorus Stress Response
Sonya T. Dyhrman,Bethany D. Jenkins,Tatiana A. Rynearson,Mak A. Saito,Melissa L. Mercier,Harriet Alexander,LeAnn P. Whitney,Andrea Drzewianowski,Vladimir V. Bulygin,Erin M. Bertrand,Zhijin Wu,Claudia R. Benitez-Nelson,Abigail Heithoff +12 more
TL;DR: Data demonstrate that diatom P deficiency results in changes in cellular P allocation through polyphosphate production, increased P transport, a switch to utilization of dissolved organic P through increased production of metalloenzymes, and a remodeling of the cell surface through production of sulfolipids.
