Carbon and oxygen isotope characteristics of carbonate rocks in the Mesoproterozoic Jixian System of the Ordos Basin and their implications [PDF]
Scientific Reports, 2023 The paleoenvironment of Jixian carbonate rocks in the Mesoproterozoic Ordos Basin is studied by carbon and oxygen isotope analyses, diagenetic environment analysis, and the restoration of paleosalinity and paleotemperature.

Water Isotopologues as a Quantitative Paleosalinity Proxy [PDF]
Paleoceanography, 2011 Paleosalinity reconstructions are a goal of paleoceanographic study because of their potential to provide insight into past ocean circulation. While temperature reconstructions have been assessed by using multiple independent proxies, the skill of existing salinity reconstructions remains poorly quantified. We examine the applicability of two different

Groundwater Transport in a Glaciomarine Aquitard: Paleosalinity and Landslide Implications. [PDF]
Ground WaterAbstract Leaching of marine salinity in the porewater of glaciomarine muds is one precursor to landslide hazard. In this study, groundwater modeling is used to quantify vertical groundwater flow, constrain paleosalinity, and characterize past and future progression of leaching with depth in Champlain Sea sediments.

Progress in Paleosalinity: Overview and Presentation of a New Approach [PDF]
Paleoceanography, 2007 This paper concerns the use of stable oxygen isotope ratios (δ18O) and stable hydrogen isotope ratios (δ2H or δD) to derive paleosalinity. First, I evaluate the potential and limitations of existing methods based on δ18O and δD separately. Next, I propose a new theoretical framework for the combined use of δ18O and δD to constrain the impact of the ...

Quantitative Reconstruction of the Paleosalinity at Qinghai Lake in the Past 900 Years
Chinese Science Bulletin, 2004 Based on the function relationship between the shell length ofLimnocythere inopinata and the salinity of its living water in Tibetan Plateau lakes, the paleosalinty of Qinghai Lake in the past 900 years was reconstructed through the measurement of the adult body length ofLimnocythere inopinata.

Modeling Water Isotopologues During the Last Glacial: Implications for Quantitative Paleosalinity Reconstruction [PDF]
Paleoceanography, 2015 AbstractQuantitative paleosalinity reconstructions with reasonable uncertainties remain a challenge in paleoceanography. In this study, we focus on stable isotope‐based methods (δ18O and δ2H) to derive paleosalinity. We use the water isotopes‐enabled fully coupled atmosphere/ocean/vegetation/land surface three‐dimensional model of intermediate ...

A century‐long record of plant evolution reconstructed from a coastal marsh seed bank [PDF]
Evolution Letters, 2021 Evidence is mounting that climate‐driven shifts in environmental conditions can elicit organismal evolution, yet there are sparingly few long‐term records that document the tempo and progression of responses, particularly for plants capable of ...
