  • Abstract: This data set includes meteorological and soil temperature data obtained from two study areas in Eastern Siberia. The first study area is located at Lake Illirney in Chukotka, on a plateau above the treeline. The study site is located in a high-latitude boreal forest zone with alpine tundra above the treeline where the automatic weather station (AWS) is located. The annual average temperature is below zero degrees and results in continuous permafrost. One stand-alone Hobo logger for soil temperature measurements was installed in the soil pit next to the AWS. A second one at the subsite in a sparse larch-dominated forest with an average larch tree height of 12.5 m and 1 % cover of Salix shrubs with an average height of 0.9 m. The second study area is located in a typical boreal forest zone intermixed with some grassland for kettle grazing and shallow lakes. These boreal forest environments experience 6 to 8 months of freezing temperatures reaching extremes of -62 °C in winter and up to 35 °C between May and September. The annual average temperature is below zero degrees and results in continuous permafrost. The AWS is installed on a meadow surrounded by mixed boreal forest. The grassland is grazed by horses in summer and deforestation occurred more than 50 years ago. In addition, one stand-alone hobo logger was installed in the soil pit next to the AWS. In the forest, south of the AWS, a standalone Hobo logger was installed to record a vertical temperature profile. The forest is rather dense and mixed, with deciduous Larix gmelinii and evergreen Picea obovata. The average tree height is 12 m for larch and 5.5 m for spruce.

  • Abstract: Quality-controlled meteorological/snow measurement data obtained from a research-oriented automated weather station (AWS) installed in the observation field of the Institute of Low Temperature Science (ILTS), Hokkaido University, Sapporo, Japan maintained by the Meteorological Research Institute, Japan Meteorological Agency (MRI/JMA) and ILTS are presented. Originally, the AWS was installed to utilize the data for process studies related to the snow-atmosphere interaction, then contributed to the development of a physically based snow albedo model of MRI/JMA. After the success, the data were used again for the development of a detailed physical snowpack model by MRI/JMA. Apart from that, the data were used to propose a light scattering model of snow grains and snow impurities for accurate radiative transfer modeling and satellite remote sensing. Some of the data presented here have ever contributed to the international snow model inter-comparison project ESM-SnowMIP, where this observation site is the only station chosen from Asia. The dataset includes 1. Gap-filled half-hourly meteorological/snow data from November to April to drive snow models (snow depth, precipitation, wind speed, air temperature, relative humidity, surface pressure, downward shortwave and longwave radiant fluxes, solar zenith and azimuth angles, direct and diffuse components of downward visible and near-infrared radiant fluxes, ground surface heat flux, and soil temperature at 100 cm depth), 2. Half-hourly radiation measurement data for snow physical process studies from November to April (snow depth, shortwave, visible, and near-infrared albedos, snow surface temperature, downward and upward radiant fluxes, and diffuse and direct components of downward radiant fluxes), and 3. Spectral albedo and diffuse fraction data measured with a ground-based spectral radiometer system for albedo and flux (GSAF).

  • Abstract: The occurrence of well-preserved redeposited organic material is the main limitation for radio-carbon dating of syngenetic permafrost sediments. Only radiocarbon dating of (1) auto-chthonous organic remains or (2) a series of non-inverted radiocarbon dates, in the case of allochthonous organic material in permafrost thicknesses, is valid. An interpretation of oxygen isotope values from syngenetic ice-wedges is considered in the context of several syngenetic permafrost sequences for northern Eurasia. Radiocarbon dating of organic matter from the host sediments which accumulated synchronously to the ice-wedges provides an age attachment for the oxygen isotope determinations.

  • Abstract: Planktonic Foraminifera Fauna: Identification of N. pachyderma in the greater than 150 micron size fraction was carried out on split subsamples containing at least 300 whole specimens by M.J. Mleneck-Vautravers. Ice-Rafted Detritus: Lithic counts were undertaken on the same split fraction used for faunal identification by M.J. Mleneck-Vautravers. Age model: The age model was developed by aligning the abrupt transitions of d18O record of G. bulloides in core MD01-2444 to warming and cooling events in the NGRIP d18Oice record, presented on: (i) the GICC05 timescale [Svensson, A. et al. A 60,000 year Greenland stratigraphic ice core chronology. Clim. Past 4, 47–57 (2008)]; and (ii) the WD2014: modified timescale, whereby NGRIP GICC05 ice ages 31.2–67.2 ka are multiplied by 1.0063. [Buizert, C. et al. The WAIS Divide deep ice core WD2014 chronology – Part 1: Methane synchronization (68–31 ka BP) and the gas age–ice age difference. Clim. Past 11, 153-173 (2015)].
