title: n-alkane and isoprenoid concentration data, compound specific carbon isotope analysis on n-alkanes

description: These were measured on Triassic Shale samples from Stensiöfjellet.Extraction and Measurement are described in (Publication name) .

In the Excel document the data is organized following:Sheet 1: n-alkane and isoprenoid peak intensities Sheet 2: n-alkane and isoprenoid concentration data in ug/g sedimentSheet 3: compound specific carbon isotope analysis on n-alkanes

For the CSV format each sheet is saved as a different file.STABMpeakIntensities: n-alkane and isoprenoid peak intensities STABMalkisoconcentration: n-alkane and isoprenoid concentration data in ug/g sedimentSTABMcscia: compound specific carbon isotope analysis on n-alkanes
description: Following the largest mass extinction of the Phanerozoic, the Early Triassic was  characterized by a series of carbon cycle perturbations as revealed through multiple global carbon isotope excursions (δ13C). The mechanistic drivers behind these perturbations are a subject of debate and remain uncertain due to limited records that differentiate terrestrial and marine carbon cycling processes. In this study, we focus on the Smithian-Spathian boundary, which is characterized by a global positive carbon isotopic excursion approximately 2 million years after the onset of the carbon cycle perturbations. We present the results of biomarker molecular distributions and compound-specific (i.e. n-alkanes) carbon isotope analyses (δ13Cn-alkane) extracted from shales deposited at Stensiöfjellet section in Spitsbergen, Norway. The molecular δ13Cn-alkane data suggest  that both marine and terrestrial systems were equally affected by carbon cycle perturbations. It also shows the onset of the positive carbon isotopic excursion was  in the late middle Smithian. Long-chained n-alkane carbon isotopic compositions are compatible with a shift in terrestrial vegetation from lycophytes to gymnosperms, which affected the fractionation of carbon during photosynthesis. Associated δ13C values of biomarkers from the marine system likely changed in concert with dissolved organic carbon compositions as controlled by local fluvial input, atmospheric carbon dioxide concentrations, marine primary productivity, and temperature. Considered together, our complementary geochemical data shed light on the complex interplay between terrestrial and marine carbon cycle dynamics in the Early Triassic (Smithian-Spathian) and foster useful insights into the mechanistic consequences of rapid cycle perturbations during an interval of extreme environmental conditions and continuous biological radiation and extinction pulses.

title: Geochemical Data from Stensiöfjellet

description: This is the raw data belonging to a manuscript published in Lethaia called Palaeoenvironmental variability and carbon cycleperturbations during the Smithian-Spathian (Early Triassic) in Central Spitsbergen (DOI: 10.18261/let.57.2.1) as well as Chapter 2 of the PhD thesis titled: Deciphering Complexities of the Organic Carbon Cycle across the Smithian and Spathian Substages of the Early Triassic.
description: Sheet 1: Isotope and RockEval Data

The dataset includes carbon, nitrogen and oxygen isotope data (bulk Delta13C_org, bulk Delta13C_Carb, Delta18O carb, bulk Delta15N), Total organic carbon (TOC), Total nitrogen (TN), Yield in CaCO3, RockEval Pyrolysis data (HI, OI, Tmax, S1, S2 and S3 peaks),

 

Sheet 2: XRF Data

The Dataset includes elemental concentrations measured by XRF in ppm of Rb, Yr, Th, U

 

Sheet 3: P + ICP-OES Data

The Dataset inludes elemental concentrations measured with the ICP-OES in ppm P, Al, Mo, Ti, V, K, Na and calcualted CIA values.
description: The Early Triassic Smithian and Spathian time intervals are characterized by perturbations in the global carbon cycle, fluctuations in sea surface temperature, high turnover rates of marine nekton, and a change in terrestrial vegetation. Despite the importance of this time interval, comprehensive multiproxy investigations from Early Triassic high and middle latitude regions remain scarce due to the difficulty in accessing sections. The objective of this study is to increase our understanding of regional and local palaeoenvironmental and carbon cycle perturbations from a middle Smithian to late Spathian middle latitude section from Central Spitsbergen. Geochemical analyses show an increase in phosphorus and nitrogen just at and above the Smithian–Spathian boundary (SSB). High primary productivity led to increasingly anoxic conditions in bottom waters during the middle and late Spathian, enhancing the preservation of organic matter in the sediments. Anoxic conditions restrain phosphorus remineralization, allowing it to be recycled within the water column. This increase in anoxia is consistent with observations in other Arctic basins, demonstrating larger regional similarities in palaeoenvironmental conditions. The fluctuations in isostatic and eustatic sea levels affected organic carbon sequestration by regulating organic matter mineral interactions via the control of grain size within the sediment. This study demonstrates that local organic carbon sequestration in the Barents Sea shelf during the Spathian was influenced by a multitude of factors, including sedimentology, redox conditions, nutrient availability, and primary productivity.
