Acknowledgments Many thanks to the numerous Eckerd College undergraduate students who
helped in the laboratory and at sea including Brigid Carr, Shannon Hammaker, Chloe Holzinger,
Farley Miller, Claire Miller, and Corday Selden. Grateful acknowledgments to Alan Shiller, who
provided important insight at a critical time. We are grateful to the exceptional crew of the R/V
Weatherbird II for their skilled help at sea collecting samples and staying safe during the field
operations.
This research was made possible by funding from The Gulf of Mexico Research Initiative to
the Center for the Integrated Modeling and Analysis of the Gulf Ecosystem (C-IMAGE)
Consortium Deep and the Deep Sea to Coast Connectivity in the Eastern Gulf of Mexico (Deep-C)
Consortium. We also acknowledge partial funding for summer student support from Eckerd
College NSSRP program. The complete data set, including all elements determined by ICP-MS,
can be accessed at the GRIIDC website: https://data.gulfresearchinitiative.org/ (doi: 10.7266/
N7DN43JM; 10.7266/N7C24TD; 10.7266/N7RX9914).
