title: Crystal c-axes (fabric analyser G50) of ice core samples (vertical thin sections) collected from the polar ice core EGRIP, 111-1714 m depth

description: Fabric Analyser data was obtained from 744 vertical thin sections (ca. 6.7 x 9 cm) of the East Greenland Ice Core Project (EGRIP) ice core to analyze the microstructural evolution and internal deformation with depth. Vertical ice thin sections were prepared and measured with the Fabric Analyzer G50 (resolution: 20 μm/pixel) in the field at the EGRIP site in the summer seasons of 2017 and 2018. 55 cm long samples were cut into six thin sections and measurements were later background corrected and processed with the program cAxes. The stated depth (in m) of the section describes the sections' top, center, and bottom. The derived data is the number of grains, mean grain size (in pixel and μm^2), sum vector norm, regelungsgrad, regelungsgrad weighted, concentration parameter, concentration parameter weighted, spherical aperture, spherical aperture weighted, three eigenvalues (e1, e2, e3, and weighted e1, e2, e3), woodcock parameter and woodcock parameter weighted.

title: Total nitrogen from solid phase in the Jena Experiment (Main Experiment up to 30cm depth, year 2002)

description: This data set contains measurements of total nitrogen from the main experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained by bi-annual weeding and mowing. Soil sampling and analysis: Stratified soil sampling was performed before sowing in April 2002. Five independent samples per plot were taken using a split tube sampler with an inner diameter of 4.8 cm (Eijkelkamp Agrisearch Equipment, Giesbeek, the Netherlands). Soil samples were dried at 40°C and then segmented to a depth resolution of 5 cm giving six depth subsamples per core. All samples were analyzed independently and averaged values per depth layer are reported. Sampling locations were less than 30 cm apart from sampling locations in other years. Subsequently, samples were dried at 40°C. All soil samples were passed through a sieve with a mesh size of 2 mm. Rarely present visible plant remains were removed using tweezers. Total nitrogen concentration was analyzed on ball-milled subsamples (time 4 min, frequency 30 s-1) by an elemental analyzer at 1150°C (Elementaranalysator vario Max CN; Elementar Analysensysteme GmbH, Hanau, Germany).
description: In 2002 and 2007, measurements of total nitrogen in a depth of up to 1m (depth resolution of 5 cm giving 20 depth subsamples) are available. In addition to measurements of total nitrogen determined from dried soil samples, measurement of dissolved nitrogen in soil solution and measurements of mineral nitrogen from KCl-extractions of soil samples are available.This datasets is part of a time series of soil nitrogen measurements in the Main Experiment since 2002 (doi:10.1594/PANGAEA.854372).

title: Stable isotopes and radiocarbon measurements of sediment core MD99-2220

description: The 51.58 m long marine sediment core MD99-2220 was raised from the Laurentian Channel in the St. Lawrence Estuary during the IMAGES-V (International Marine Past Global Change Study) oceanographic expedition, in July 1999, on board the Marion Dufresne II, using the Calypso piston corer. It provided very high-resolution records of middle to late Holocene paleoceanography changes (e.g., de Vernal et al., 2011) and a reference paleomagnetic record (St-Onge et al., 2003). After splitting, the sediment core has been subsampled at 1-cm interval and analyzed at the Geotop-UQAM Research Center. The volume of wet sediment subsamples was measured by water displacement. Subsamples were weighed, then air-dried and weighed again. Percentages of organic carbon and calcium carbonate were measured by Coulometer. Samples for geochemical analysis were dried at 60°C and then ground to fine powder using an agate mortar. Total carbon and nitrogen measurements were performed on ground aliquots, using a Carlo-Erba™ elemental analyzer. Another aliquot was then acidified twice with HCl (1 M) to remove carbonates, washed, dried, and divided into two portions for stable isotope analysis and determination of residual carbon content, considered to represent the organic carbon (OC) fraction. OC and N contents are expressed in dry weight percent of total sediment. Uncertainties, as determined from replicate measurements of standard substances, are estimated to average ±5% relative for OC and N contents. Aliquots for isotopic analysis were combusted in a quartz tube for 1 h at 850°C in the presence of purified cupric oxide wire and high-quality granular copper (e.g., Macko, 1981). The gases were then analyzed on a VG-PRISM™ instrument. Isotope data of OC and N are reported in δ ‰ values, after usual corrections (Craig, 1965), and with reference to V-PDB (Coplen, 1996), and atmospheric N, respectively. Uncertainties were lower than ±0.1‰, as determined from routine replicate measurements of standards. Whenever present, tests of the benthic foraminifera Globobulimina auriculata were hand-picked from the 125–250 μm fraction for δ18O and δ13C analyses. CO2 was extracted at 90°C using an ISOCARB™ device on-line with a VG-PRISM™ mass spectrometer. All measurements were made using an in-house standard marble calibrated against the Carrara marble and other current standard materials of the International Atomic Energy Agency of Vienna. Results were converted to the VPDB scale (Coplen 1996) after usual corrections (Craig 1957). The overall analytical reproducibility, as determined from replicate measurements on the in-house standard material, was routinely better than ±0.05‰ (±σ) for both δ13C and δ18O. Mollusk shell fragments were handpicked for AMS 14C dating at the Isotrace Radiocarbon Laboratory of the University of Toronto.

title: Ant abundance and occurrence along the plant diversity gradient in the Jena Experiment (Main Experiment, year 2006)

description: This data set contains measurements of ant abundance (number of individuals observed at the baits) and ant occurrence (binary data) measured in the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). Ants were sampled in 80 plots of the Main Experiment using baited traps in July 2006. In each plot two petri dishes were set on the ground, one received ~10g of Tuna the other ~10g of sugar (Sucrose). After 30min the occurrence (presence = 1 / absence = 0) and abundance (number) of ants at the two baits was recorded. Given is, per plot, the sum of ants attracted to the two different baits. In the Main Experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown in the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, or 4 functional groups). Plots were maintained by bi-annual weeding and mowing.
description: The main experiment on the field site of the Jena Experiment comprises a split-plot design in which additional treatments (e.g. no weeding allowing for invasion of other species, or application of fertilizer) have been applied to subplots along the outer margin of the plots (see Treatment description in the section “further details”). While in this dataset only data from the core area (mown and weeding of all none-sown species twice a year, no additional treatments) is reported, all potential treatments are listed as the first parameters in the data file to guarantee compatibility with other datasets that include different treatments.This dataset is part of a collection of measurements on invertebrate abundances and diversities in the Jena Experiment. Data for other taxonomic groups, from other experiments (e.g. Main Experiment, Dominance Experiment; see details above), other years, or other methods quantifying related data might be available (doi:10.1594/PANGAEA.865172).

title: Prosome length as well as carbon and nitrogen content of Calanus finmarchicus from the North Atlantic collected during Maria S. Merian cruise MSM26 in spring 2013

description: The prosome length of copepods from each station was measured on board with a dissecting microscope equipped with an ocular micrometer. Individuals were placed in pre-weighed tin caps and dried for 48 h at 60°C on board. Dry samples were transferred to the AWI and weighed again. Copepod dry mass was then calculated as the difference between the empty weight and the weight of the tin cap containing one individual. The content of carbon (C) and nitrogen (N) then was analysed with a CN-analyser (EuroEA Element Analyser, Hekatech) with acetanilide as standard.

title: Adult and early life stages of fish collected, taxonomically identified and enumerated from standardized trawling across the Scotia Sea, Antarctica, during austral summer 2019

description: We provide here a curated set of data containing fish catch weights and number of specimens taxonomically identified to lowest possible taxonomic level (species, genus, or family), specimen images annotated with taxonomic characters of pelagic, benthopelagic and mesopelagic fish, including their early life stages. Accession numbers for curated specimens (Department of Natural History, University Museum of Bergen, Bergen, Norway), and mitochondiral cytochrome c oxidase I (COI) at GenBank are provided. At sea Voucher specimens for the University Museum of Bergen were frozen at -20⁰C. Later on land specimens larger than 20-25 cm were fixed in 4% formalin and then transferred and stored in 70% ethanol, smaller specimens were directly stored in 70% ethanol. Fish brought back from FV Cabo de Hornos were preserved in 96% ethanol for later examination and verification on land. Tissue samples for genetic analysis were stored in 96% ethanol. The specimens were collected by a Macroplankton trawl (~36 m² mouth opening, non-graded mesh with 3 mm light-opening) and a Harstad trawl from two expeditions across the Scotia Sea, Antarctica during austral summer (January-March) 2019. The collected material is obtained from standardized V-shaped hauls down to a maximum depth of ~200 m (Macroplankton trawl) and ~1000 m (Harstad trawl), although some shallower hauls are included either to look at vertically migrating adult mesopelagic fish that enter the epipelagic domain during nighttime hours, or because of depth restrictions due to shallow bottom topography.

title: Phosphorus content and elemental ratios of gelatinous and soft-bodied zooplankton from the Northeast Pacific

description: Climate change and anthropogenic disturbances, among other factors, can change the seawater stoichiometry (C/N/P) and consequently elemental ratios of phytoplankton. This change in prey stoichiometry may not be tolerated by all grazer/predator species. Gelatinous and soft-bodied zooplankton (GZ) are suggested to be more resilient to such changes. We sampled GZ species (12 taxa in total) in the Northeast Pacific off British Columbia (Canada), determined their phosphorus (P) content and elemental ratios (C/P, N/P), and analysed intraspecific variability associated with size and ontogeny. P was determined as orthophosphate after acidic oxidative hydrolysis with 5 % H2SO4 according to Grasshoff et al. (1999). Carbon (C) and nitrogen (N) data were taken from Lüskow et al. (2021). P % DW (dry weight) decreased with size for Aequorea sp., Aurelia labiata, Cyanea capillata, and Salpa aspera (species with sufficient sample sizes). P % DW differed significantly for two development stages of the salp S. aspera. C/P and N/P were mostly size- and stage-independent. C/P values of GZ were generally higher than values of crustacean zooplankton.

title: Metrics of Benthosema glaciale collected during RV G.O. Sars cruise 2013107 across the North Atlantic in 2013

description: The data is used in a comparative analysis of the diet of one of the globally most numerous myctophids, the Glacier lantern fish Benthosema glaciale, across four deep basins of the North Atlantic. B. glaciale is a small fish species that contribute to carbon flux to the deep basins of the open ocean, and is thus considered an important element of the biological carbon pump (BCP). Data submitted is length and weight of fish analyzed for stomach content. Sampling were undertaken onboard the RV G.O. Sars during a six week long transatlantic scientific survey from Bergen (Norway) to Nuuk (Greenland) and back to Bergen in May and June 2013. The Harstad trawl is a graded (variable mesh size), small mid-water trawl with 20 m vertical opening and 15 m wing spread (Godø et al., 1993). The Macroplankton trawl on the other hand is a light pelagic trawl that has a nominal 6x6 m trawl opening and mesh size of 3 mm square light opening (8 mm stretched, knot to knot) from the trawl mouth along the entire trawl length to the cod-end (Hassel et al., 2017; Klevjer et al., 2020).
description: Maturity:Immature (1): The gonads are small. No visible egg/milk.Maturing (2): The gonads are larger in volume. Visible egg/milk, but not running.Spawning (3): Running gonads. A light press on the abdomen causes egg/milk to come out.Spent/Resting (4): The gonads are small, slack and bloody. Regeneration begins, gonads are slightly larger and fuller than in immature stage. No visible egg/milk.Unknown (5): Only used if there is uncertainty between stages immature and spent/resting.Stomach fullness:Empty (1): The stomach is completely empty, perhaps except for a little water.Very little content (2): So small that the stomach preferably needs to be opened to confirm it is not empty.Some content (3): It appears clearly from the outside that the stomach is not empty.Full (4): The stomach is full, but not bursting.Bursting (5): The abdomen is clearly distended and tight. The content is visible through the lining.Quality of biological analysis: "Low" was also used to indicate that these fish were considered part of a training set not used in further analysis.Funding and ship time were also received from the Institute of Marine Research, Bergen, Norway.

title: Stomach contents of Benthosema glaciale collected during RV G.O. Sars cruise 2013107 across the North Atlantic in 2013

description: The data is used in a comparative analysis of the diet of one of the globally most numerous myctophids, the Glacier lantern fish Benthosema glaciale, across four deep basins of the North Atlantic. We present taxonomic information, weight and number of prey items of each fish that has stomach content, as long as it has been possible to assign prey to a species or other taxonomic category. Unidentified prey usually had a high degree of digestion and individual items could not be counted, but could be weighed. Sampling were undertaken onboard the RV G.O. Sars during a six week long transatlantic scientific survey from Bergen (Norway) to Nuuk (Greenland) and back to Bergen in May and June 2013. The Harstad trawl is a graded (variable mesh size), small mid-water trawl with 20 m vertical opening and 15 m wing spread (Godø et al., 1993). The Macroplankton trawl on the other hand is a light pelagic trawl that has a nominal 6x6 m trawl opening and mesh size of 3 mm square light opening (8 mm stretched, knot to knot) from the trawl mouth along the entire trawl length to the cod-end (Hassel et al., 2017; Klevjer et al., 2020).
description: Prey digestion level:Undigested (1): Digestion has not begun, and the stomach content appears fresh.Digestion commenced (2): Species can be easily identified.Advanced digestion (3): The species can no longer be identified but can be separated into systematic groups.Late-stage digestion (4): Only residues like eyes and robust part of animals can separated into systematic groups.Nearly complete digestion (5): The stomach contents are stewed or mushy, cannot be identified or counted.Quality of biological analysis: "Low" was also used to indicate that these fish were considered part of a training set not used in further analysis.Funding and ship time were also received from the Institute of Marine Research, Bergen, Norway.
