title: Elevation of catchment area of Lake Łódzko-Dymaczewskie, Lake Dębno and Lake Trześniowskie in Poland

description: The dataset contains systematic observations of water parameters (t [°C], conductivity [μS·cm-1], pH, oxygen [mg·L-1], oxygen saturation [%], ORP [mV], TOC [mg·L-1], DOC [mg·L-1], chlorides [mg·L-1], sulphates [mg·L-1], nitrates [mg·L-1]), stable isotope composition of DIC (δ13CDIC; ‰V-PDB) and trace gas (CH4 [nmol·L-1], N2O [nmol·L-1], H2S [mg·L-1]) distribution in the water columns of three inland freshwater lakes in Poland (central-eastern Europe). The observations were collected monthly between July 2019 and July 2020 as well as quarterly between July 2021 and September 2022 from Lake Łódzko-Dymaczewskie, Lake Dębno and Lake Trześniowskie. The lakes show considerable variability of trophic conditions from mesotrophic (L. Trześniowskie) to highly eutrophic/hypetrophic (L. Łódzko-Dymaczewskie) as well as catchment morphology and land use. The bathymetric data and catchment characteristics for each lake are also provided in our database. The hadrochemical measurements and sampling was done in the deepest site in each lake using standard methods. H2S was determined spectrophotometrically on-site and the CH4 and N2O were analysed in the laboratory using gas chromatography. SO42-, Cl- and NO3- were determined with ion chromatography, HCO3- was manually titrated with HCl with regard to dye and DOC/TOC was analysed with TOC analyzer. Detailed methodology was described by Woszczyk & Schubert (2023). Creation of this dataset aimed at providing the first comprehensive set of information on the occurrence and formation of trace gases in Polish lakes. Special focus was put on potent greenhouse gases (CH4 and N2O), which are expected to increase owing to the ongoing climate warming and accompanying environmental changes (Bartosiewicz et al. 2019). Such database is to extend the existing datasets from northern and western Europe by including observations from aquatic systems in which the GHG data was missing altogether. In addition, to the best of our knowledge, our database is one of the very few, to provide the limnological and biogeochemical community with systematic H2S data. So as GHG, the accumulation of this highly toxic gas in lake waters is projected to accelerate in the following decades. Our data can be used for calculating accumulation rates in water columns as well as to assess atmospheric emissions from lakes. Catchment and hadrochemical data can be used to decipher processes behind production and release of the trace gases from lakes to the ambient air.

title: Seawater carbonate chemistry and hatch and viability of Lingcod embryos

description: Early life history stages of marine fishes are often more susceptible to environmental stressors than adult stages. This vulnerability is likely exacerbated for species that lay benthic egg masses bound to substrate because the embryos cannot evade locally unfavorable environmental conditions. Lingcod (Ophiodon elongatus), a benthic egg layer, is an ecologically and economically significant predator in the highly-productive California Current System (CCS). We ran a flow-through mesocosm experiment that exposed Lingcod eggs collected from Monterey Bay, CA to conditions we expect to see in the central CCS by the year 2050 and 2100. Exposure to temperature, pH, and dissolved oxygen concentrations projected by the year 2050 halved the successful hatch of Lingcod embryos and significantly reduced the size of day-1 larvae. In the year 2100 treatment, viable hatch plummeted (3% of normal), larvae were undersized (83% of normal), yolk reserves were exhausted (38% of normal), and deformities were widespread (94% of individuals). This experiment is the first to expose marine benthic eggs to future temperature, pH, and dissolved oxygen conditions in concert. Lingcod are a potential indicator species for other benthic egg layers for which global change conditions may significantly diminish recruitment rates.

title: Soil exchangeable cation concentration map of Amazonia, link to GeoTif

description: Maps of soil cation concentration as modelled using direct and plant-derived soil data together as input data:-KrigeSoill_fernRcropNEW.tif - covering the whole Amazonian sensu latissimo. One single interpolation without wetlands claasification.-KrigeAvg_MaskWETfern_Soil.tif - Two krigings were run separately for wetlands and uplands and ovelaped to compose a single map (map extent limited to the area covered by the available wetlands map).-KrigeSoill_fernERRORNEW.tif - degree of uncertainty in predicted values as quantified by the Kriging variance associated with map KrigeSoill_fern.tif. To obtain a standard deviation map use the variance map to the power of 2 (KrigeSoill_fernERRORNEW.tif ^2).-KrigeAvg_WETLANDfern_SoilERROR.tif - degree of uncertainty in predicted values as quantified by the Kriging variance associated with map KrigeAvg_MaskWETfern_Soil.tif. To obtain a standard deviation map use the variance map to the power of 2 (KrigeAvg_WETLANDfern_SoilERROR.tif ^ 2).Methods in brief:We defined fern species optima using compiled data from 1,353 quantitative fern and lycophyte inventory plots across Amazonia that also provided locally measured soil cation concentration. We obtained and cleaned species occurrence records from the Global Biodiversity Information Facility (GBIF; http://www.gbif.org) and SpeciesLink (http://www.splink.org.br) and assigned a soil value to each of the georeferenced records according to the exchangeable cation concentration optima estimated for the species (hereafter fern-derived soil points). We combined the fern-derived soil points with soil points provided by Harmonized World Soil Database v1.2 (HWSD) (Nachtergaele et al. 2012) and Brazilian National database (BND) (Cooper et al. 2005). We generated exchangeable cation concentration maps using both direct and indirect environmental data as input points for interpolation using ordinary Kriging. We validated the maps using external soil information from 194 plots of the Amazon Forest Inventory Network (RAINFOR).--The files are in .tif format and consist of digital spatial layers that can be opened in QGIS, R and other GIS or spatial analysis programs.

title: A new high-resolution magnetic scanner for sedimentary sections

description: We developed a fully automated magnetic field scanner dedicated to uniaxial magnetic field measurements to determine remanent magnetization intensities and their variations in sedimentary U channels. A fluxgate magnetometer located as close as possible from the sedimentary section is used to perform uniaxial measurements of magnetic fields locally generated by isothermal remanent magnetization. This artificial magnetization, which is known to be a powerful proxy in environmental magnetism, is produced perpendicular to the U channel long axis, and parallel to the fluxgate axis, using a Halbach cylinder prior to the measurement. The magnetic scanner offers a maximal spatial resolution of 5.8 mm. The spatial resolution of 14 mm is obtained for U channel samples. The magnetic scanner covers a large range of magnetic field signals including those that saturates the Superconducting Rock Magnetometer in its classical configuration. The estimation of the remanent magnetization intensities along the U channel is based on a modeling approach that uses successive uniformly magnetized prisms. In lacustrine laminated sections, comparison between modeling results based on prisms of a constant thickness, on prisms determined from sedimentary facies and on prisms determined from XRF (X-Ray Fluorescence), data helps to understand the detrital vs. diagenetic history of the sedimentary succession.

title: Seawater carbonate chemistry and skeletal isotopic composition and calcifying fuid composition in co-occurring Porites and Diploastrea specimens across the Pacifc ocean

description: The Tara Pacifc expedition (2016–2018) provided an opportunity to investigate calcifcation patterns in extant corals throughout thePacifc Ocean. Cores from colonies of the massive Porites and Diploastrea genera were collected fromdiferent environments to assess calcifcation parameters of long-lived reef-building corals. In this study, we compared the calcifcation and carbonate chemistryup-regulation of Diploastrea heliopora and Porites corals from across a range of environments. To this, we analyzed the skeletal geochemistry and growth parameters of 39 colonies of Porites (n=33) and Diploastrea (n=6) collected across the tropical Pacifc Ocean during the Tara Pacifc expedition (2016–2018). Te collected corals represent a suite of cores exposed to various hydrological conditions of seawater temperature (SST: 22.4–29.8 °C), salinity (SSS: 31.5–36.1), and carbonate chemistry (total scale pHsw: 8.01–8.09). Te average chemical composition of the calcifying fuid (pHcf, [CO32−]cf, DICcf, Ωcf) was derived from paired boron isotope (δ11B) and B/Ca analyses of core-top samples corresponding to the last 6 years of growth (2010–2016). Based on these data, we assessed the impact of the ambient seawater properties (SST, salinity, carbonate chemistry) on the cf composition of these slow-growing reef-building genera at the Pacifc basin scale.

title: Seawater carbonate chemistry and coelomic fluid,morphometric and survival data of Paracentrotus lividus

description: Inter‐individual variation in phenotypic traits has long been considered as "noise" rather than meaningful phenotypic variation, with biological studies almost exclusively generating and reporting average responses for populations and species' aver‐ age responses. Here, we compare the use of an individual approach in the investigation of extracellular acid-base regulation by the purple sea urchin Paracentrotus lividus challenged with elevated pCO2 and temperature conditions, with a more traditional approach which generates and formally compares mean values. We detected a high level of inter‐individual variation in acid-base regulation parameters both within and between treatments. Comparing individual and mean values for the first (apparent) dissociation constant of the coelomic fluid for individual sea urchins resulted in substantially different (calculated) acid-base parameters, and models with stronger statistical support. While the approach using means showed that coelomic pCO2 was influenced by seawater pCO2 and temperature combined, the individual approach indicated that it was in fact seawater temperature in isolation that had a significant effect on coelomic pCO2. On the other hand, coelomic [HCO3−] appeared to be primarily affected by seawater pCO2, and less by seawater temperature, irrespective of the approach adopted. As a consequence, we suggest that individual variation in physiological traits needs to be considered, and where appropriate taken into ac‐ count, in global change biology studies. It could be argued that an approach reliant on mean values is a "procedural error." It produces an artefact, that is, a population's mean phenotype. While this may allow us to conduct relatively simple statistical analyses, it will not in all cases reflect, or take into account, the degree of (physiological) diversity present in natural populations.

title: Dinocyst assemblages in sediment core MSM05/3_343310 from Disko Bugt, West Greenland

description: Palynological analyses of sediment core MSM343310 from Disko Bugt (68°38.861' N, 53°49.493' W) document decadal‐ to centennial‐scale variability of sea surface conditions during the last ~3,600 years. Dinocyst fluxes (&gt;10⁴ cysts/cm² yr⁻¹) indicate a very high productivity. Dinocyst assemblages dominated by Islandinium minutum, Brigantedinium spp., Islandinium? cezare, and the cyst of Pentapharsodinium dalei suggest low surface salinity and marked shifts in summer sea surface temperature. The application of the modern analog technique to dinocyst assemblages, using an updated reference data set with new sites from the West Greenland margin, led to reconstruct decadal‐centennial‐scale variations in sea surface salinity and temperature, in phase with the δ18O variations in the Camp Century ice core. At ~1.5 ka BP, the seasonal sea ice cover records an important regime change, from winter‐only sea ice to more unstable conditions marked by successive cooling pulses with sea ice cover of up to 8 months/yr. The data suggest a close relationship between hydrographic conditions and regional climate over Greenland. Our record shows variations with a mean 200 years periodicity until ~2 ka BP, which supports the hypothesis of climate variations driven by solar variability. After 1.5 ka BP, our data show a variability characterized by a 60-70 year periodicity, which suggests linkages with the Atlantic Multidecadal Oscillation and southwestward migration of the atmospheric polar front. The most recent part of the record, from ~1900 CE to 2007 CE, is characterized by assemblages reflecting warmer surface conditions and reduced sea ice cover.
