Journal ArticleDOI
The carbonic anhydrase activity of sinking and suspended particles in the North Pacific Ocean
TL;DR: In this paper, the enzyme carbonic anhydrase (CA) is crucial to many physiological processes involving CO₂, from photosynthesis and respiration, to calcification and CaCO₃ dissolution.
Journal ArticleDOI
Brachiopod δ34SCAS microanalyses indicate a dynamic, climate-influenced Permo-Carboniferous sulfur cycle
TL;DR: A new record of Carboniferous and Early Permian brachiopod δ 34 S CAS generated from over 130 measurements of micro-sampled brachiopsod shells is presented in this article.
Book ChapterDOI
Development and Initial Biogeochemical Applications of Compound-Specific Sulfur Isotope Analysis
Paul F. Greenwood,Alon Amrani,Alex L. Sessions,M. R. Raven,Alex I. Holman,G. Dror,Kliti Grice,Malcolm T. McCulloch,Jess F. Adkins +8 more
TL;DR: In this paper, compound-specific isotope analysis (CSIA) has been extended to the stable isotopes of sulfur (δ(34)S) through the combination of gas chromatography (GC) and multi-collector inductively coupled mass spectrometry (ICPMS).
Quantification and Isotopic Analysis of Intracellular Sulfur Metabolites in the Dissimilatory Sulfate Reduction Pathway
Min Sub Sim,Min Sub Sim,Guillaume Paris,Guillaume Paris,Jess F. Adkins,Victoria J. Orphan,Alex L. Sessions +6 more
TL;DR: In this paper, the authors report the concentrations and isotopic ratios of sulfur metabolites in the dissimilatory sulfate reduction pathway of Desulfovibrio alaskensis and interpret this pattern to indicate that enzymatic fractionations remain large but the net fractionation between sulfate and sulfide is muted by the closed-system limitation of intracellular sulfate.
Journal ArticleDOI
The Role of the Southern Ocean in Abrupt Transitions and Hysteresis in Glacial Ocean Circulation
TL;DR: In this paper, a time-dependent coarse-resolution isopycnal model with four density classes and two basins, linked by a Southern Ocean, was used to explore overturning states and their stability to changes in external parameters.
