Journal ArticleDOI
Urea Uptake and Carbon Fixation by Marine Pelagic Bacteria and Archaea during the Arctic Summer and Winter Seasons
TL;DR: SIP experiments indicated a strong seasonal shift of bacterial and archaeal N utilization from ammonium during the summer to urea during the winter but did not support a similar seasonal pattern of nitrate utilization.
Journal ArticleDOI
Preliminary estimates of the contribution of Arctic nitrogen fixation to the global nitrogen budget
Rachel E. Sipler,Donglai Gong,Steven E. Baer,Marta P. Sanderson,Quinn N. Roberts,Margaret R. Mulholland,Deborah A. Bronk +6 more
TL;DR: In this paper, the authors reported rates of 3.5-17.2 nmol N L−1 d−1 in the ice-free coastal Alaskan Arctic to show that N2 fixation in the Arctic Ocean may be an important source of nitrogen to a seasonally nitrogen-limited system.
Journal ArticleDOI
Parallel phylogeography of Prochlorococcus and Synechococcus.
Alyssa G. Kent,Steven E. Baer,Céline Mouginot,Jeremy S. Huang,Alyse A. Larkin,Michael W. Lomas,Adam C. Martiny +6 more
TL;DR: This study demonstrates that Prochlorococcus and Synechococcus have shared phylogenetic organization of traits and associated phylogeography, suggesting uniquely adapted populations at very specific depths, as well as between the Atlantic and Pacific Oceans.
Journal ArticleDOI
Nutrient supply controls particulate elemental concentrations and ratios in the low latitude eastern Indian Ocean
Catherine A. Garcia,Steven E. Baer,Nathan S. Garcia,Sara Rauschenberg,Benjamin S. Twining,Michael W. Lomas,Adam C. Martiny +6 more
TL;DR: It is shown that nutrient supply, over temperature and biodiversity changes, controls regional variation of elemental ratios in the tropical Indian Ocean.
Journal ArticleDOI
Effect of temperature on rates of ammonium uptake and nitrification in the western coastal Arctic during winter, spring, and summer
Steven E. Baer,Steven E. Baer,Tara L. Connelly,Rachel E. Sipler,Patricia L. Yager,Deborah A. Bronk +5 more
TL;DR: In this paper, the sensitivity of ammonium (NH4+) uptake and nitrification rates to short-term warming was studied in the Chukchi Sea off the coast of Barrow, Alaska during winter, spring, and summer and incubated for 24h in the dark with additions of 15NH4+ at −1.5, 6, 13, and 20°C.
