Autor: Laura E. Sofen, Olga A. Antipova, Michael J. Ellwood, Naomi E. Gilbert, Gary R. LeCleir, Maeve C. Lohan, Claire Mahaffey, Elizabeth L. Mann, Daniel C. Ohnemus, Steven W. Wilhelm, Benjamin S. Twining

Publikováno v: Limnology and Oceanography Letters, Vol 7, Iss 4, Pp 354-362 (2022)

Abstract Nano‐ and picophytoplankton are a major component of open‐ocean ecosystems and one of the main plankton functional types in biogeochemical models, yet little is known about their trace metal contents. In cultures of the picoeukaryote Ost

Taxonomic and nutrient controls on phytoplankton iron quotas in the ocean

Autor: Benjamin S. Twining, Olga Antipova, P. Dreux Chappell, Natalie R. Cohen, Jeremy E. Jacquot, Elizabeth L. Mann, Adrian Marchetti, Daniel C. Ohnemus, Sara Rauschenberg, Alessandro Tagliabue

Publikováno v: Limnology and Oceanography Letters, Vol 6, Iss 2, Pp 96-106 (2021)

Abstract Phytoplankton iron contents (i.e., quotas) directly link biogeochemical cycles of iron and carbon and drive patterns of nutrient limitation, recycling, and export. Ocean biogeochemical models typically assume that iron quotas are either stat

The interplay between regeneration and scavenging fluxes drives ocean iron cycling

Autor: Alessandro Tagliabue, Andrew R. Bowie, Timothy DeVries, Michael J. Ellwood, William M. Landing, Angela Milne, Daniel C. Ohnemus, Benjamin S. Twining, Philip W. Boyd

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

Iron is crucial for marine photosynthesis, but observational constraints on the magnitude of key iron cycle processes are lacking. Here the authors use a range of observational data sets to demonstrate that the balance between iron re-supply and remo

Dissolved and Particulate Barium Distributions Along the US GEOTRACES North Atlantic and East Pacific Zonal Transects (GA03 and GP16): Global Implications for the Marine Barium Cycle

Publikováno v: Global Biogeochemical Cycles. 36

Processes controlling dissolved barium (dBa) were investigated along the GEOTRACES GA03 North Atlantic and GP16 Eastern Tropical Pacific transects, which traversed similar physical and biogeochemical provinces. Dissolved Ba concentrations are lowest
