title: Carbon Isotope Signatures and Polyarenes in the Pedogenic Material of Ice Wedges of the Batagay Yedoma (Yakutia)

description: The carbon isotope signatures and the content of polycyclic aromatic hydrocarbons (PAHs) in the pedogenic material of inclusions in ice wedges of the Batagay yedoma (Yakutia) are studied. The mean concentration of 11 PAHs is 170 ppb (minimum, 7 ppb and maximum, 430 ppb) and the mean δ13С value in soil lipids is -29‰ (minimum, -31.1‰ and maximum, -26.2‰). The prevalent polyarenes in associations are naphthalene homologs and phenanthrene. Trace amounts of heavy PAHs, including benzo[a]pyrene (an indicator of pyrogenic processes), are also detectable. The PAH contents and δ¹³С values in ice wedges show the trend of a decrease with depth. The δ¹³С values and PAH content suggest a pedogenic origin of the deposit: therefore, PAHs originate from plant residues and wildfires. The observed trend of changes in the concentrations of polyarenes along the ice wedge may be associated with the changes in landscapes in the Late Pleistocene.
description: 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.The samples are represented by sediment extracted from ice wedges after ice melting in a plastic container. Content of organic carbon (%), δ¹³С values (‰), and PAH content was measured in samples from the Batagay ice wedges.The sediment was dried to assess the carbon content in dry samples. The carbon content was measured at the Ecological and Geochemical Center of the Geographical Faculty of Lomonosov Moscow State University on a Vario EL III v. 4.01 (Elementar Analysen systeme GmbH, Germany) CHNS analyzer using sulfanilic acid (Merck; 41.610% C) as a standard.The samples (hexane extracts) were analyzed for PAHs content at the Laboratory of Carbonaceous Substances in the Biosphere, Department of Landscape Geochemistry and Soil Geography, Geographical Faculty, Lomonosov Moscow State University, by spectrofluorometry (Shpol'skii method) using a cryounit (Pikovskii et al., 2017).The isotopic composition of lipid compounds was determined by mass spectrometry. The lipids were separated from soil inclusions in the ice wedges by cold chloroform and hexane extraction (Korchagina, Chetverikova, 1976). The isotopic composition of carbon was determined at the Isotope Laboratory of the Faculty of Geography, Lomonosov Moscow State University, on a Delta-V Plus isotope ratio mass spectrometer with a standard EA 1112 HT O/H-N/C element analyzer. IAEA-CH-3, IAEA-CH-6, IAEA-600, and USGS-24 international standards were used for measurements; δ¹³C determination accuracy was ±0.2‰.

title: Reconstructed ice thickness fields for Kersten Glacier (KG) and the Northern Icefield (NIF) on Mt. Kilimanjaro for the 2011 glacier extent at 2 m model resolution

description: Glaciers on Kilimanjaro are unique indicators for climatic changes in the tropical mid-troposphere of Africa. The history of severe glacier area loss raises concerns about an imminent future disappearance. Yet, the remaining ice volume is not well known. We reconstruct thickness maps for 2000 and 2011 for the Northern Icefield (NIF) and Kersten Glacier (KG) that are informed by ground-truth thickness measurements and multi-temporal satellite information. For 2011, we find mean thickness values of 26.6 and 9.3 m, respectively. The existing consensus estimate for global glacier ice thickness shows unrealistically thick values for KG in areas that are meanwhile ice-free.The ice thickness fields show the ice thickness in meters for the 2011 reconstruction (Experiment 3) outlined in the linked publication.

title: UAV imagery over K-sector of the Greenland Ice Sheet on 8 August 2014

description: Digital imagery acquired by a Sony NEX-5N digital camera vertically mounted inside a fixed-wing UAV. The UAV surveyed a 25 km east-west transect dissecting the dark zone of the K-sector of the Greenland Ice Sheet on 8 August 2014. The camera has a 16 mm fixed focus lens (53.1 by 73.7° field of view) yielding an image footprint of approximately 525 x 350 m during the autonomous sortie. The camera was preset with a fixed shutter speed of 1/1000 s, ISO 100 and F-stop of 8. The images have a pixel footprint of approximately 11 cm. A corresponding csv file provides the UAV geolocation and attitude data for each image. The data were logged by an Arduino navigation and flight computer in real-time by a 10 Hz data stream comprising of a GPS, magnetometer, barometer and accelerometer.

title: Taxonomic composition of zooplankton and frequency of occurrence of the taxa (% of samples) in the small river of the industrial zone of Volga region

description: The presented species list of zooplankton is a summary of long-term observations that took place on the small river Stepnoy Zai, situated in the industrial zone of the Middle Volga region of Russia. The sampling took place in May, July, and September yearly from 2008 to 2019 from 4 sampling stations along the river Stepnoy Zai. The sampling stations were situated upstream and downstream of municipal wastewater discharges of the four cities located in the upper (Bugulma, Leninogorsk), middle (Almetievsk), and lower (Zainsk) reaches of the river. Sampling was performed using Apstein Net from the upper water horizons. Samples were concentrated to 100 ml, and fixed with 4% formaldehyde solution.

title: Full panorama images of 51 field plot centres during the expedition to Central Yakutia, summer 2021

description: During an expedition to central Yakutia in summer 2021, full panoramic images of the sampled vegetation plots were captured for documentation purposes. The images were taken with a 360 camera (Samsung Gear 360) and from the centre 2-4 images recorded at the centre position of the vegetation plot standing at different positions. The images were stitched in the supplied software to 360x180 panorama images (7776x3888 pixels, raw images). These were aligned in Hugin Panorama Software (https://hugin.sourceforge.io/) and humans or other artificial objects masked. The final panorama was blended and gaps or human shadow errors healed with GIMP resynthesizer plugin (https://github.com/bootchk/resynthesizer) and exported into one image with 7776x3888 pixels.

title: Seawater carbonate chemistry and shell growth and coloration of important Northwest Atlantic bivalve species

description: To investigate the response of four commercially relevant bivalve species to OA and differing temperatures, juvenile Mercenaria mercenaria (hard shell clams), juvenile Mya arenaria (soft shell clams), adult and juvenile Arctica islandica (ocean quahog), and juvenile Placopecten magellanicus (Atlantic sea scallops) were grown in varying pH and temperature conditions. Species were exposed to four controlled pH conditions (7.4, 7.6, 7.8, and ambient/8.0) and three controlled temperature conditions (6, 9, and 12˚C) for 20.5 weeks and then shell growth and coloration were analyzed. This research marks the first direct comparison of these species' biological responses to both temperature and OA conditions within the same experiment.This dataset is included in the OA-ICC data compilation maintained in the framework of the IAEA Ocean Acidification International Coordination Centre (see https://oa-icc.ipsl.fr). Original data were provided by the author of the related paper (see Related to) to the OA-ICC data curator. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2024) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2025-02-21.

description: During an expedition to northern Yakutia in summer 2014, full panoramic images of the sampled vegetation plots were captured for documentation purposes. The images were taken with a standard camera (Nikon Coolpix P7000) from the centre of the vegetation plots. At each, multiple rows of images in all directions were recorded holding the camera at a fixed position at breast height (1.3 m above ground). The images were stitched in Autopano Giga 4 (Kolor) and humans or other artificial objects masked if possible. Blended images were exported to 360x180 panorama images (10000x5000). The panorama image was manually checked for gaps or human shadow errors which were healed with GIMP resynthesizer plugin (https://github.com/bootchk/resynthesizer).
