title: Oxygen isotope composition of Late Pleistocene syngenetic ice wedges from the Seyakha yedoma, Eastern Yamal Peninsula

description: Variations in δ¹⁸О were measured in the samples of Late Pleistocene ice wedge, collected in 2016 on the shore of the Gulf of Ob, near the Seyakha settlement. The values of δ¹⁸О in the upper fragment of the ice wedge vary from –25.75 to –23.15‰. The amplitude of horizontal variations in δ¹⁸О at +15.2 m height is 1.49‰ (–23.41 to –24.9‰). The lower fragment of the ice wedge at +6 m height is characterized by a broader variation range of δ¹⁸O compared to the upper one: δ¹⁸О varies in the horizontal direction from –23.41 to –26.63‰
description: The isotope dates of water and ice samples were obtained at the isotope laboratory of the Department of Geography, Moscow State University, using a Delta-V mass spectrometer with a standard gas-bench option.

title: δ²H, δ¹⁸O and Deuterium excess values in Holocene multistage massive ice near the Sabettayakha River mouth, Yamal Peninsula, northwest Siberia

description: Holocene massive ground ice near the Sabettayakha River mouth, on the coast of the Gulf of Ob, Yamal Peninsula, northwest Siberia is studied. The multistage massive-ice bodies have thickness up to 5.7 m and occur in Holocene sediments of modern floodplain and the first terrace of the coastal lagoon. Stable isotope analyses revealed that the multistage massive ice bodies formed syngenetically during the freezing of water- saturated sediment, under intensive cryogenic fractionation.
description: Isotopic analyses were performed in the Stable Isotope Laboratory of the Geographical Department of Lomonosov Moscow State University using a mass spectrometer Finnigan Delta-V with the standard gas -bench option. International standards V-SMOW (Vienna Standard Mean Ocean Water), GISP (Greenland Ice Sheet Precipitation) and SLAP (Standard Light Antarctic Precipitation), as well as the laboratory's own standard -fresh snow of the Cauca- sus glacier Garabashi ( δ¹⁸О= -15.60 ‰ , δ²H = -110.0 ‰ ) were used for the measurements. The precision of the δ¹⁸О and δ²H measurements is 0.1 and 0.6 ‰, respectively.Data was submitted and proofread by Yurij K Vasil'chuk and Lyubov Bludushkina at the faculty of Geography, department of Geochemistry of Landscapes and Geography of Soils, Lomonosov Moscow State University.Funding was received from the Russian Science Foundation (Award nr. 19-17-00126, field research), the Russian Foundation for Basic Research (Award nr. 18-05-60272, isotope analysis).

title: Depth of massive ice bodies near the Sabettayakha River mouth, Yamal Peninsula, northwest Siberia

description: Holocene massive ground ice near the Sabettayakha River mouth, on the coast of the Gulf of Ob, Yamal Peninsula, northwest Siberia is studied. Three boreholes (Nr 12, 17 and 42) were drilled within the Holocene lagoon-marine floodplain of the Ob Bay and the first lagoon-marine terrace near the Sabettayakha River mouth in winter 2014 using a light portable drill. The drilling retrieved a 12 cm diameter core in an almost undisturbed condition. Massive ice was sampled from these boreholes for isotope, chemical and palynologic analyses. The multistage massive-ice bodies have thickness up to 5.7 m and occur in Holocene sediments of modern floodplain and the first terrace of the coastal lagoon. The ratio of the chloride and sulfate anions, pollen spectra and presence of algae in three different types of massive ice near the Sabettayakha River mouth suggest that vertically layered brown ice formed during freezing of water-saturated sands of the Ob Gulf; brown non-laminated ice formed as a result of freezing of sublake talik water; and white ultra-fresh ice also formed from lake and river water.
description: Fragments about 30 cm long of three ice cores were taken from each borehole, transported in frozen state to Moscow, and kept in a freezer.Data was submitted and proofread by Yurij K Vasil'chuk and Lyubov Bludushkina at the faculty of Geography, department of Geochemistry of Landscapes and Geography of Soils, Lomonosov Moscow State University.Funding was received from the Russian Science Foundation (Award nr. 19-17-00126, field research) and the Russian Foundation for Basic Research (Award nr. 18-05-60272, isotope analysis).

title: Ion concentration, salinity and total dissolved solids (TDS) in Holocene multistage massive ice near the Sabettayakha River mouth, Yamal Peninsula, northwest Siberia

description: Holocene massive ground ice near the Sabettayakha River mouth, on the coast of the Gulf of Ob, Yamal Peninsula, northwest Siberia is studied. Three boreholes (Nr 12, 17 and 42) were drilled within the Holocene lagoon-marine floodplain of the Ob Bay and the first lagoon-marine terrace near the Sabettayakha River mouth in winter 2014 using a light portable drill. The drilling retrieved a 12 cm diameter core in an almost undisturbed condition. Massive ice was sampled from these boreholes for isotope, chemical and palynologic analyses. The ion concentration (%-equivalent - %-eq), salinity (S) and total dissolved solids (TDS) concentration was determined in newly melted snow, lake ice, sea ice and sea water. A single series of geochemical analysis of massive ice with other cryospheric objects was carried out for more reliable comparison and correct interpretation of geochemical data.
description: Cation and anion concentrations in the ice were measured immediately after the ice melted, in the Chemical-Analytical Centre of the Geographical Department of Lomonosov Moscow State University by ion chromatography "Stayer" with a conductivity detector. The limit for chloride ions is considered 0.02 μg/mL. The accuracy and precision over a wide concentration range, and total uncertainty (including random and systematic errors reported at the 95% confidence level) of anion and cation determinations were further estimated and the values were found to be sufficient for analysis of the ice.Data was submitted and proofread by Yurij K Vasil'chuk and Lyubov Bludushkina at the faculty of Geography, department of Geochemistry of Landscapes and Geography of Soils, Lomonosov Moscow State University.Funding was received from the Russian Science Foundation (Award nr. 19-17-00126, field research) and the Russian Foundation for Basic Research (Award nr. 18-05-60272, isotope analysis).

title: Pollen and spores in massive ice, snow, sea ice and ice wedges

description: Palynologic analyses were carried out in Holocene massive ice, snow and ice wedges from sampling locations at the Yamal peninsula and the Yamal Nenets region in Siberia.
description: Sample processing for the palynologic analyses included KOH deflocculation, treatment with HF (except for the samples of pure ice without ground or low concentration of ground particles) and mounting of pollen samples in glycerine. To simplify the process and prevent pollen loss, the samples were not subjected to either acetolysis. Cytoplasm in the pollen grains is not chemically removed, which allowed us to separate fresh pollen grains and reworked ones. Pollen percentages calculate based on the total pollen and spore sum.Data was submitted and proofread by Yurij K Vasil'chuk and Lyubov Bludushkina at the faculty of Geography, department of Geochemistry of Landscapes and Geography of Soils, Lomonosov Moscow State University.Funding was received from the Russian Science Foundation (Award nr. 19-17-00126, field research) and the Russian Foundation for Basic Research (Award nr. 18-05-60272, isotope analysis).

title: Concentration of individual polychlorinated biphenyl congeners in surficial freshwater sediments from a contaminated wastewater lagoon

description: We report the results of individual polychlorinated biphenyl (PCB) congeners in the surficial freshwater sediment from a wastewater lagoon located in Virginia (USA). PCB congeners were measured using tandem mass spectrometry (GC-MS/MS) in multiple reaction monitoring mode (MRM), a method that provides a high-level selectivity and sensitivity for PCBs in complex environmental samples. The PCB concentrations (sum of 171 congeners or coeluting peaks) range from 6,340 to 12,700,000 ng/g dry weight (d.w.). PCB congener profile of samples resembles commercial mixture Aroclor 1248, with the exception of one sample.

title: Carbon isotope ratios in bulk organic matter (δ¹³Corg) and organic carbon contents (TOC), sediment core 4523-A

description: This file includes new data on the carbon-isotope composition of bulk organic matter (δ¹³Corg) and organic carbon contents (TOC, wt%) from the core 4523-A (Sedlec), western part of the Bohemian Cretaceous Basin. The interval covers the uppermost Cenomanian through Middle Turonian. Samples were analyzed in the Stable Isotope Laboratory of the Geological Survey, Prague. Inorganic carbon was removed before analysis by acid washing with HCl followed by rinsing with water, drying at 60 °C and homogenisation. Carbon-isotope measurements were performed by flash combustion in Fisons 1108 elemental analyzer coupled with isotope ratio mass spectrometer Delta V Advantage (ThermoFisher, Bremen, Germany) in continuous flow regime. Sample size was adjusted to contain a sufficient amount of carbon. Isotope ratios are reported as delta (δ) values and expressed relative to VPDB. International standards NBS 22 (-30,031‰), IAEA-CH-7 (-32,151‰) and in-house standard Soil (-27,82 ‰) were used to verify proper instrument function, and to conduct a normalization procedure. The long-term reproducibility is better than ±0.15‰.

title: Carbon isotope ratios in bulk organic matter (δ¹³Corg), sediment core 4530-A

description: This file includes new data on the carbon-isotope composition of bulk organic matter (δ¹³Corg) from the core 4530-A (Horní Beřkovice), western part of the Bohemian Cretaceous Basin. The interval covers the uppermost Cenomanian through Middle Turonian. Samples were analyzed in the Institute of Geochemistry, Mineralogy and Mineral Resources, Charles University, Prague. Stable isotopic composition of carbon was determined using a Thermo Flash 2000 elemental analyzer connected to a Thermo Delta V Advantage isotope ratio mass spectrometer in a Continuous Flow IV system. Minimal weight of samples depends on the wt.% amount of carbon element. Samples wrapped in tin capsules were combusted. Released gases (CO2) separated in a GC column was transferred to MS source through a capillary. Isotope ratios are reported as delta (δ) values and expressed relative to VPDB. Delta values are normalized to a calibration curve based on international standards IAEA-CH-6, IAEA-CH-3 and IAEA 600.
