title: Biogeochemistry analysis of sediment core Co1412 in the Yana Highlands

description: The sediment succession of Lake Emanda in the Yana Highlands was investigated to reconstruct the regional late Quaternary climate and environmental history. Hydro-acoustic data obtained during a field campaign in 2017 show laminated sediments in the north-western and deepest (up to ~15 m) part of the lake, where a ~6-m-long sediment core (Co1412, latitude 65°17.6490N, longitude 135°45.5540E) was retrieved. The sediment core was studied with a multi-proxy approach including sedimentological and geochemical analyses. The chronology of Co1412 is based on 14C AMS dating on plant fragments from the upper 4.65 m and by extrapolation, suggesting a basal age of c. 57 cal. ka BP.Biogeochemistry analysis of sediment Co1412: TOC=total organic carbon (%), TN=total nitrogen (%), TOC/TN (atomic), TS=total sulphur (%), TIC=total inorganic carbon (%) data of sediment Co1412 against composite depth (cm) and age (cal. a BP).

title: (Appendix) Bulk inorganic chemistry at DSDP Leg 77 Holes

description: Clay mineralogic and inorganic geochemical investigations of Cretaceous and Cenozoic sediments of the western Gulf of Mexico lead to the following main conclusions. (1) Transition of lowermost Cretaceous continental to marine sedimentation is marked by a clay evaporitic stage, north of the Campeche Escarpment. (2) Existence of combined mineralogic and geochemical stratigraphy allows us to propose correlations between Sites 535 and 540, especially for the Albian. (3) Predominance of detrital clay assemblages is indicative of hot and variably humid continental climate until the early late Cenozoic. (4) Tectonic destabilization of the margins of Gulf of Mexico occurred at different periods, especially until the middle Cretaceous, with a mixed erosion of rocks and soils and temporary oxidized conditions of deposition. (5) Successive developments of confined perimarine basins occurred from the earliest Cretaceous until the Miocene, chiefly in the Florida area. The sources of inorganic materials were chiefly situated on the east of the studied area until the late Tertiary and after that in the Mississippi River basin. (6) Occasionally, volcanic activity influenced the clay mineralogy and mainly the geochemistry, and possibly contributed to the rather strong magnesian character of the deposition until the late Paleogene. (7) The argillaceous diagenesis is weak; variability of the carbonate diagenesis is marked by the relation Sr = f(CaO) and chiefly depends on the depth of burial, the clay content, the porosity, and the geologic age.

title: Mesozooplankton biomass during Mikhail Lomonosov cruise ML27, Part I

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 125 µm. Additionally, the JUDAY oceanic model JOM with 300 µm mesh size and 80 cm ring diameter was used. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-300, 300-500 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxonomic groups - to type, class, order and family levels.

title: (Table 1) Tree age, post fire stand age, and soil organic matter thickness in the western Quebec black spruce boreal ecosystem

description: The observed long-term decrease in the regional fire activity of Eastern Canada results in excessive accumulation of organic layer on the forest floor of coniferous forests, which may affect climate-growth relationships in canopy trees. To test this hypothesis, we related tree-ring chronologies of black spruce (Picea mariana (Mill.) B.S.P.) to soil organic layer (SOL) depth at the stand scale in the lowland forests of Quebec's Clay Belt. Late-winter and early-spring temperatures and temperature at the end of the previous year's growing season were the major monthly level environmental controls of spruce growth. The effect of SOL on climate-growth relationships was moderate and reversed the association between tree growth and summer aridity from a negative to a positive relationship: trees growing on thin organic layers were thus negatively affected by drought, whereas it was the opposite for sites with deep (&gt;20-30 cm) organic layers. This indicates the development of wetter conditions on sites with thicker SOL. Deep SOL were also associated with an increased frequency of negative growth anomalies (pointer years) in tree-ring chronologies. Our results emphasize the presence of nonlinear growth responses to SOL accumulation, suggesting 20-30 cm as a provisional threshold with respect to the effects of SOL on the climate-growth relationship. Given the current climatic conditions characterized by generally low-fire activity and a trend toward accumulation of SOL, the importance of SOL effects in the black spruce ecosystem is expected to increase in the future.

title: (Table 1) Deuterium excess record during different time periods in Lomonosovfonna ice core

description: In this paper we present a deuterium excess (d) record from an ice core drilled on a small ice cap in Svalbard in 1997. The core site is located at Lomonosovfonna at 1255 m asl, and the analyzed time series spans the period 1400-1990 A.D. The record shows pronounced multidecadal to centennial-scale variations coherent with sea surface temperature changes registered in the subtropical to southern middle-latitude North Atlantic during the instrumental period. We interpret the negative trend in the deuterium excess during the 1400s and 1500s as an indication of cooling in the North Atlantic associated with the onset of the Little Ice Age. Consistently positive anomalies of d after 1900, peaking at about 1950, correspond with well-documented contemporary warming. Yet the maximum values of deuterium excess during 1900-1990 are not as high as in the early part of the record (pre-1550). This suggests that the sea surface temperatures during this earlier period of time in the North Atlantic to the south of approximately 45°N were at least comparable with those registered in the 20th century before the end of the 1980s. We examine the potential for a cold bias to exist in the deuterium excess record due to increased evaporation from the local colder sources of moisture having isotopically cold signature. It is argued that despite a recent oceanic warming, the contribution from this local moisture to the Lomonosovfonna precipitation budget is still insufficient to interfere with the isotopic signal from the primary moisture region in the midlatitude North Atlantic.

title: Archaeobotanical analyses at Oldenburg 108, Burgstrasse, Lower Saxony, Germany - counts

description: From two profiles of an archaeological trench in the centre of the city Oldenburg 108, Burgstr. , Lower Saxony, two largely overlapping cores, 50 (length) x 10 (width) x 5 (thickness) cm, of highly organic sediments were taken and one sample of about 2 l in a plastic bag from the northern profile 44 in 2005 (June 2nd). Subsamples were taken following the layers in the metal boxes, sieved in the laboratory using stacked sieves of mesh-sizes 1, 0.71 and 0.3 mm and botanical macroremains were picked out using a microscope (magnification 10x-50x), identified and counted in the course of 2006. The identified remains (seeds, fruits, vegetative remains, zoological remains) dating to the Late Medieval were assigned to ecological groups allowing the reconstruction of the environmental conditions at the time of deposition. The aims of the analyses were to reveal which human activities took place at the place, which cultural plants can be traced, which structures were present, what kind of sediment has been investigated (the preliminary assumption by the archaeologists has been peat) and how old are the remains/features.

title: (Table 1) Interstitial water chemistry at DSDP Leg 78A Holes

description: Studies of interstitial water carried out during Deep Sea Drilling Project Leg 78A (Sites 541, 542, and 543) have revealed that alteration of volcanic material dispersed in the sediments is largely responsible for increased concentrations of dissolved calcium and decreased concentrations of dissolved magnesium and potassium. This conclusion is supported by studies of the 87Sr/86Sr ratio of dissolved strontium, as well as by studies of the oxygen isotopic composition of interstitial waters. At Site 543 a large part of the d18O decrease in the interstitial waters must result from diffusive exchange with underlying basement rocks. Data from studies of interstitial water do not indicate upward advection of fluids at Sites 541 and 542.

title: Light intensity time series from 16 locations in Lovns Bredning, Limfjorden, Denmark, at 0.5 m above seabed, 28-February-2017

description: Field studies were conducted in two different areas of the Limfjorden, in Lovns Bredning (26th February to 4th March 2017) and in Løgstør Bredning (6-10th March 2017). In each sampling area, 16 fixed-position moorings were deployed in two circular sensor arrays around a mussel dredging area to investigate possible effects of dredging related sediment plumes (Pastor et al, 2020). The inner array (stations 1 - 8) had a diameter of 200 m and the outer array (stations 9 - 16) was set up with a diameter of 600 m. Integrated temperature and light loggers (HOBO Pendant Temperature/Light 64K Data Logger) were mounted on each mooring in the two circular arrays at three different water depths (0.5, 1.5 and 3.0 m above seabed). The 48 loggers (3 depths and 16 stations) were deployed in each area over a period of four days and light intensity time series were collected with a sampling interval of 30 seconds. Five loggers in the Lovns area did not provide any data due to technical problems (two near-surface loggers and three loggers at 1.5 m above the seabed). However, only one bottom logger at Løgstør Bredning failed to provide data. Each time series was filtered using a 3-minute moving average for removing the largest outliers, but retaining sharp changes in light intensity associated with short-lived sediment plumes caused by experimental mussel dredging.
