The distributions of these phases are poorly constrained and undersampled in the oceans, despite interactions between living organisms and non-living minerals having central roles within many globally relevant biogeochemical processes. Through a combination of method development, basin-scale particulate collection and analyses, modeling, and field experiments, this thesis examines both the distributions of marine particulate trace metals and the underlying processesinputs, scavenging, vertical and horizontal transport, and biotic uptake-in which marine particles participate.
I first present the results of an intercalibration exercise among several US laboratories that analyzed filtered particles on shared polyethersulfone filters. We Mahowald lab4 present a new chemical method for complete dissolution of polyethersulfone filters and compare it to other total particle digestion procedures.
Inputs of lithogenic particles from African dust sources, hydrothermal systems, benthic nepheloid layers and laterally-sourced margin influences are observed and discussed. Lithogenic particle residence times, size-fractionation patterns, Ti-mineral speciation, and relationships to biological aggregation processes are calculated and described.
A one-dimensional, sizefractionated, multi-box model that describes lithogenic particle distributions is also proposed and its parameter sensitivities and potential implications are discussed.
The thesis concludes with the presentation of results from a series of bottle incubations in naturally iron-limited waters using isotopically labeled Fe-minerals. We demonstrate both biotic and abiotic solubilization of the minerals ferrihydrite and fayalite via transfer of isotopic label into suspended particles.
These results are the first of their kind to demonstrate that minerals can be a source of bioavailable iron to euphotic communities and that spatial and ecological variations in mineral Fe-bioavailability may exist.
Associate Scientist 3 Acknowledgements Although this thesis has my name on it, every page bears the watermark of my brilliant and ever thoughtful advisor, Phoebe J. Thank you so much for providing me with exciting projects, invigorating afternoon data conversations, prompt and thoughtful written feedback, and what I'm sure was a lifetime's worth of patience over the years.
Together we've travelled to the bottom of the world, sampled oceans, and spent nights by the hum of a synchrotron; it's hard to imagine doing research without your insight. Thanks also to my illustrious thesis committee: Your advisorship and feedback were invaluable to keeping my goals in sight.
I thank every friend, colleague and institution employee who's helped guide my way and shaped my graduate school experiences. My good friends and roommates Abby Heithoff, Michael Toomey, and Liz Bonk made coming home from aborted cruises or long nights combating matrix effects in the Plasma Facility something extra special.
I will always look fondly on my years sharing a home with you and my stupid cats. The nearly innumerable but I'll try! Thank you all so much just for being you.
Thank you all for so many cherished memories. Nine year-old Dan 0. And now it's published forever. The captains, crews, and dock-side teams of all the research vessels and institutions involved in sample collection deserve special acknowledgement.
