A Proposed Improvement for Measuring Hydroxylamine in Seawater
Hydroxylamine is a chemical intermediate in the nitrogen cycle that can quickly react via biotic and abiotic processes to yield nitrous oxide, a potent greenhouse gas. Because of its high reactivity, hydroxylamine tends ... -
Characterizing iron reducing microorganisms from anoxic ferruginous lake sediments
Lake Matano, Indonesia is a well-known ancient ocean analogue as its anoxic ecosystem in the subsurface sediments allow the growth of microorganisms capable of mediating anaerobic oxidation coupled to iron reduction. An ... -
Earth's oxygen and phosphorus cycle and the evolution of animal life
The purpose of this study is to reconstruct an environmental context for the emergence and expansion of early animal life during the Middle Proterozoic (∼1.8–0.8 billion years ago). Specifically, we examined the spatially ... -
Transport Pathways of Shelf Source Micronutrients to the Southern Ocean
(Georgia Institute of Technology, 2015-08-18)We use a numerical ocean model to evaluate the hypothesis that the continental shelves are significant sources of dissolved iron to the Southern Ocean. We simulate the distribution of passive tracers released from the 18 ...
