title: Relative eelgrass leaf elongation and microalgal epiphyte load on eelgrass leaf measured through a multi-factorial in situ experiment of 10 weeks in a eelgrass bed in St. Lawrence Estuary (Baie-Saint-Ludger, Canada)

description: We evaluated single and interactive effects of density reduction of Zostera marina L., a habitat-forming species, shading, and sediment nutrient enrichment on the response of eelgrass relative leaf elongation (RLE) and of microalgal epiphyte load on leaves. REL was evaluated once, as a proxy for growth, using five shoots per plot that were each marked with a reference hole at the top of the sheath using a pushpin marked at the end of Period T1 (two weeks after reducing eelgrass density and at the same time than adding nutrients sediment enrichment and shades). After 19 days, we collected the shoots and brought them back to the lab where leaf elongation was measured as the displacement of the mark relative to the reference mark on the oldest nongrowing leaf (Olesen & Sand-Jensen 1994). Total leaf elongation was then divided by sheath length and the number of days of elongation. We estimated the epiphyte (microalgae) load on eelgrass by scraping the leaves of one randomly selected shoot; we then filtered the water containing the epiphytes on GF/F filters that were then kept wrapped in aluminum foil at -80 °C until analysis. Epiphyte load was assessed using chlorophyll extraction with 90% acetone, following Parsons et al. (1984). Calculated chlorophyll weight was then divided by shoot dry weight.

title: Abundances of intertidal macro-species measured through a multi-factorial in situ experiment of 10 weeks in a eelgrass bed in St. Lawrence Estuary (Baie-Saint-Ludger, Canada)

description: We evaluated single and interactive effects of density reduction of Zostera marina L., a habitat-forming species, shading, and sediment nutrient enrichment on the response of intertidal epibenthic macro-species abundances. Abundances were measured two weeks after reducing eelgrass density (Period T1), then nutrients were added to the sediments and shades were added above the bed. Abundances were measured three weeks later (Period T2), then shades were taken down. Final abundances were measured five weeks later (Period T3). Epibenthos was collected using mesh bags (mesh size of 500 µm, diameter about 18 cm), each individual collected was identified then sifted through a series of sieves as a proxy for biomass (ash free dry weight; AFDW).

title: Biomass (dry weight) of epiphytic microalgae measured through a multi-factorial in situ experiment of 10 weeks in a eelgrass bed in St. Lawrence Estuary (Baie-Saint-Ludger, Canada)

description: We evaluated single and interactive effects of density reduction of Zostera marina L., a habitat-forming species, shading, and sediment nutrient enrichment on the response of microalgal epiphyte load on eelgrass leaves. We estimated the epiphyte (microalgae) load on eelgrass by scraping eelgrass leaves with a microscope slide under filtered seawater. During Period T1, we selected and scraped the leaves of three randomly selected shoots. We then filtered the water containing the scraped epiphytes through preweighed GF/F filters, and we assessed the epiphyte load as the dry weight of epiphytes divided by the dry weight of the collected scraped shoots.

title: CTD cast locations in the Lena Delta region

description: This data set includes the CTD cast locations, which were measured during the CACOON 2019 expeditions (Fuchs et al., 2021; Strauss et al., 2021) in the Lena Delta region in Siberia.The data collection took place during two field campaigns; the first one was in March-April 2019, the second one in August 2019. Measurements were taken with a handheld SontekTM CastAway sensor with an integrated GPS. The measured data include pressure, depth, temperature, conductivity, specific conductance, salinity, sound velocity, and density. In total, 31 depth profiles were measured from the Sardakhskaya main river channel in the Lena Delta to 80 km offshore in the Laptev Sea to specifically target the mouth area of the Sardakhskaya channel. The CTD was lowered from water surface with an additional ballast to make sure the small CTD device reached the sea (or river) bed.This data sets includes detailed data about the locations, time and duration of CTD measurements in the Lena Delta region.

title: Isotope composition of snow cover on a long transzonal profile of Western Siberia from Tomsk to the Gulf of Ob (2014)

description: The study of the snow cover is of paleogeographic, paleogeocryological, and paleohydrological importance. Isotope composition (δ¹⁸О, δD, dexc) of the snow cover on a long transect of Western Siberia from the southern taiga to the tundra was investigated from February 19 to March 4, 2014. Snow samples were collected at 31 sites. Most of the samples represented by fresh snow were collected in two areas. In the area of Yamburg, the snow specimens collected from the surface are most probably settled snow of different ages. The values of δ¹⁸О in the snow from Tomsk to Yamburg varied from –21.89 to –32.82‰, and the values of δD, from –163.3 to –261.2‰. The value of deuterium excess was in the range of 4.06–19.53‰. The study of stable isotopes of oxygen and hydrogen of the snow led to identification of latitudinal zoning of the snow cover in the central continental part of western Siberia associated with the temperature mode at the time of precipitation.
description: The specimens were analyzed using a Finnigan Delta-V mass spectrometer in the isotope laboratoryof the Department of Geography, Moscow State University. International standards V-SMOW, GISP, and SLAP were used for measurements; the test error was ±0.6‰ for δD and ±0.1‰ for δ¹⁸O.

title: n-Alkane composition of organic matter in a rapidly eroding permafrost cliff

description: Organic carbon (OC) stored in Arctic permafrost represents one of Earth’s largest and most vulnerable terrestrial carbon pools. Amplified climate warming across the Arctic results in widespread permafrost thaw. Permafrost deposits exposed at river cliffs and coasts are particularly susceptible to thawing processes. Accelerating erosion of terrestrial permafrost along shorelines leads to increased transfer of organic matter (OM) to nearshore waters. However, the amount of terrestrial permafrost carbon and nitrogen as well as the OM quality in these deposits are still poorly quantified. Here, we characterise the sources and the quality of OM supplied to the Lena River at a rapidly eroding permafrost river shoreline cliff in the eastern part of the delta (Sobo-Sise Island). Our multi-proxy approach captures bulk elemental, molecular geochemical and carbon isotopic analyses of late Pleistocene Yedoma permafrost and Holocene cover deposits, discontinuously spanning the last ~52 ka. We show that the ancient permafrost exposed in the Sobo-Sise cliff has a high organic carbon content (mean of about 5 wt%).We found that the OM quality, which we define as the intrinsic potential to further transformation, decomposition, and mineralization, is also high as inferred by the lipid biomarker inventory. The oldest sediments stem from Marine Isotope Stage (MIS) 3 interstadial deposits (dated to 52 to 28 cal kyr BP) and is overlaid by Last Glacial MIS 2 (dated to 28 to 15 cal ka BP) and Holocene MIS 1 (dated to 7–0 cal ka BP) deposits. The relatively high average chain length (ACL) index of n-alkanes along the cliff profile indicates a predominant contribution of vascular plants to the OM composition. The elevated ratio of iso and anteiso-branched FAs relative to long chain (C ≥ 20) n-FAs in the interstadial MIS 3 and the interglacial MIS 1 deposits, suggests stronger microbial activity and consequently higher input of bacterial biomass during these climatically warmer periods. The overall high carbon preference index (CPI) and higher plant fatty acid (HPFA) values as well as high C / N ratios point to a good quality of the preserved OM and thus to a high potential of the OM for decomposition upon thaw. A decrease of HPFA values downwards along the profile probably indicates a relatively stronger OM decomposition in the oldest (MIS 3) deposits of the cliff.
