Replication Data for: Preying on seals pushes killer whales from Norway above pollution effects thresholds
No full textThis dataset has been published in Scientific Reports, doi: doi: 10.1038/s41598-020-68659-y
Killer whales (Orcinus orca) are at risk from high levels of biomagnifying pollutants, such as polychlorinated biphenyls (PCBs) and mercury (Hg). Previous toxicological risk assessments for the Norwegian killer whale population have assumed fish as the primary prey source, and assessed the population as below established effect thresholds. However, some individuals have recently been identified to also feed on seals. This study is the first to quantify levels of pollutants in seal-eating killer whales from northern Norway, and to measure Hg levels in the skin of killer whales worldwide. We found higher levels of all pollutants in seal-eating than fish-eating killer whales, including the emerging brominated flame retardants pentabromoethylbenzene (PBEB), pentabromotoluene (PBT) and hexabromobenzene (HBB). Sum polychlorinated biphenyls (ΣPCBs) in the blubber of seal-eaters (n = 7, geometric mean = 46 µg/g l.w.) were four times higher than fish-eaters (n = 24, geometric mean = 11 µg/g l.w.), which pushed all seal-eating individuals above multiple thresholds for health effects. Total Hg levels in skin of seal-eaters (n = 10, arithmetic mean = 3.7 µg/g d.w.) were twice as high as in fish-eaters (n = 28, arithmetic mean = 1.8 µg/g d.w.). Our results indicate that by feeding on higher trophic prey, the Norwegian killer whale population is at higher risk of health effects from pollution than previously assumed
Replication Data for: Effect of Cu^2+ on deposition mechanism and structure of ZrO2-based conversion coatings on AA6060 aluminium alloys and their susceptibility to filiform corrosion
No full textZirconium oxide-based conversion coatings (CCs) were prepared from hexafluorozirconic acid, H2ZrF6, with and without Cu(II) as an additive. The CCs were prepared on primary and recycled AA6060. The deposition mechanism, structure, electrochemical properties and effectiveness in protection against filiform corrosion (FFC) have been explored. In presence of Cu(II) additives, a two step deposition mechanism is observed, evidenced by open circuit potential (OCP) measurements and in situ dynamic electrochemical impedance spectroscopy (dEIS). Copper deposits predominantly as copper(II) hydroxyfluoride on the top surface, and metallic Cu at the metal/CC interface, as evidenced by x-ray photoelectron spectroscopy (XPS) and glow-discharge optical emission spectroscopy (GD-OES). The presence of a Cu(II) additive induces a different distribution of the Zr oxide-based products. After deposition of a weak organic model coating, aluminium pretreated with the Cu(II)-containing system shows a 10-30% lower maximum filament length compared to the Cu(II)-free system in FFC tests, despite a ca. one order of magnitude higher cathodic activity of the former. The dataset contains raw data for reproducing the electrochemical measurements results and surface composition and structure. The data relative to the electrochemical characterization contain .txt files of open circuit potential and dynamic electrochemical impedance measurements. The data relative to the surface characterization contain .csv files for the GD-OES measurements, .vms file for the XPS measurement and .tif files for the scanning electron microscopy (SEM) pictures
Replication data for: The impact of soil hydrological regimes and vegetation systems on plant performance and root depth distribution in bioswale microcosms
No full textThis dataset represents a greenhouse experiment to investigate the effects of fluctuating soil hydrology on plant growth and vertical root distribution for vegetated infiltration systemsPlant rooting patterns in bioswales, raingardens and other vegetated infiltration systems are essential, as they contribute biopores which maintain the infiltration function over time. However, fluctuating hydrological conditions, ranging from flooded to drained, can have a heavy impact on plant rooting, as well as consequences for plant contributions to other ecosystem services and ecological functions. This study tested the biomass allocation to roots and the vertical root profile of four plant species, alone or in competition with a grass, and their responses to the experimental manipulation of soil hydrology in soil column microcosms. When the species were exposed to repeated wet-dry cycling hydrological regimes, we found a clear shift in vertical root distribution, and observed shallower rooting in wetter regimes. It was also found that alongside this shallower rooting, there were no changes to total biomass and only moderate adjustments to biomass investment in roots. Overall, differences in rooting patterns between hydrological regimes and species were moderate, although species covered a range of adaptations along the scale of moist to dry soil conditions. In fact, the addition of the grass Festuca rubra actually evened out the differences in rooting patterns among the systems and contributed to a strong increase in root mass density. Accordingly, mixed species systems may be a robust approach to vegetated infiltration systems when competitive exclusion can be prevented. Overall, it is thought that deeper rooting can be promoted by designing these systems in such a way that allows for at least periodically dry periods

Replication Data for: Terrain-Informed Self-Supervised Learning: Enhancing Building Footprint Extraction from LiDAR Data with Limited Annotations
No full textThe dataset comprises the pretraining and testing data for our work: Terrain-Informed Self-Supervised Learning: Enhancing Building Footprint Extraction from LiDAR Data with Limited Annotations. The pretaining data consists of images corresponding to the Digital Surface Models (DSM) and Digital Terrain Models (DTM) obtained from Norway, with a ground resolution of 1 meter, utilizing the UTM 33N projection. The primary data source for this dataset is the Norwegian Mapping Authority (Kartverket), which has made the data freely available on their website under the CC BY 4.0 license (Source: https://hoydedata.no/, License terms: https://creativecommons.org/licenses/by/4.0/)
The DSM and DTM models are generated from 3D LiDAR point clouds collected through periodic aerial campaigns. During these campaigns, the LiDAR sensors capture data with a maximum offset of 20 degrees from the nadir. Additionally, a subset of data also includes building footprints/labels created using the OpenStreetMap (OSM) database. Specifically, building footprints extracted from the OSM database were rasterized to match the grid of the DTM and DSM models. These rasterized labels are made available under the Open Database License (ODbL) in compliance with the OSM license requirements. We hope this dataset facilitates various applications in geographic analysis, remote sensing, and machine learning research

Replication Data for: "Likelihood of Early Contractor Involvement (ECI) benefits in infrastructure versus building projects: the client’s perception"
No full textThe use of collaborative project delivery models has been around for the last couple of decades in Norwegian infrastructure projects. Early Contractor Involvement (ECI) is a feature used in many collaborative projects as a means to onboard contractor competence early on in the project lifecycle. Recently there has been an increasing interest among practitioners in testing whether ECI can also be useful for building projects. Following a systematic literature review approach, a comprehensive list of potential benefits of ECI was identified. Using empirical data collected from 91 respondents from three client organizations through workshops and surveys, this study explores whether the use of ECI may have different effects in these two groups. Overall, results show that improved innovation, enhanced constructability, and greater collaboration are perceived to be the most likely benefits of ECI. The likelihood of benefits is also moderated by the type of project, with building projects more likely to benefit from ECI. Regarding job roles, project management professionals are the most optimistic about the likelihood of these benefits. The results also indicate that respondents without having experience with collaborative projects or ECI have a more positive outlook than those with experience. These findings contribute to creating a more holistic understanding of the effects of ECI.Description of the dataset:
This dataset contains a compilation of survey responses used in the paper. This includes 91 respondents from 3 different client organisations

Replication Data for: Reptile footprints on a pelagic seafloor as a vestige of a synsedimentary seismic event in the lower Campanian Scaglia Rossa Basin of the Umbria-Marche Apennines (Italy)
No full textThese data sets contain the raw measurements for the magnetostratigraphy presented in "Reptile footprints on a pelagic seafloor as a vestige of a synsedimentary seismic event in the lower Campanian Scaglia Rossa Basin of the Umbria-Marche Apennines (Italy)". They include the alternating field demagnetisation sequence ("BUS24_demagnetisation.csv") acquired on a cryogenic magnetometer and bulk magnetic susceptibility file with repeat measurements ("BUS24_susc.csv").
Methods
Oriented, 23-mm-diameter, 40-mm-long core samples were collected at 2.5 m intervals from the BUS section using a cordless power drill with a 2.5 cm dry concrete cup cutter. The alternating field (AF) demagnetization of magnetic remanence was measured using an Applied Physics Systems Model 755 cryogenic magnetometer at the Geological Survey of Norway. Bulk magnetic susceptibility values were measured on an AGICO MFK1-A Kappabridge at the Norwegian University of Science and Technology.
Sample orientation parameters:
Core orientation is trend of core axis and plunge (dip of core axis with respect to horizontal)
Bedding orientation is strike using right-hand rule and dipABSTRACT
A group of free climbers by chance discovered a large number of footprint traces deeply impressed on a vast pelagic limestone slab on the steep northeastern limb of the Monte Cònero anticline, near the city of Ancona (Marche region of central-eastern Italy). The footprints probably represent a stampede of panicking sea turtles that were mobilized en masse by an earthquake. These tracks were subsequently covered by a fluxoturbidite triggered by the same earthquake. The same layer is exposed in a 40-m-thick section along the littoral zone below. This new section provides the ability, through combined bio- and magneto-stratigraphic analysis, to place the footprint layer in the lower Campanian foraminiferal biozone Globotruncanita elevate and the lowermost part of magnetochron C33n. Most of this section comprises calcarenitic and calcilutitic turbidites interbedded with pelagic biomicrites, which witnessed a period of enhanced seismic activity exacerbated by a climate change-driven eustatic sea level fluctuation. Following a review of the sedimentological and tectono-seismic history of the Cretaceous Umbria-Marche paleobasin with particular attention to the Monte Cònero area, we will proceed with the description and documentation of our integrated stratigraphic analysis of the new section exposed along the northeastern littoral known as La Vela Beach
Replication data for 'Coastal lake sediments from Arctic Svalbard suggest colder summers are stormier'
No full text This dataset includes sediment analyses performed on core 601-21-6 GC (76°29'N, 16°33'E) from Lake Steinbruvatnet (Sørkappøya island, S Svalbard) and contains all data presented by Stachowska et al., 2024 (https://doi.org/10.21203/rs.3.rs-3710647/v1).
The investigated record was extracted during the summer of 2021 with a Uwitec gravity corer, analyzed throughout 2021-2023, and covers the past 9,700 cal. yrs B.P. Additionally, in the summer of 2023, we collected four sediment catchment samples (CS 1-4) to the West (CS 1) and the East (CS 2-4) of Lake Steinbruvatnet, and analysed them later in 2023 and 2024. Core 601-21-6 GC was taken to reconstruct Arctic storminess by pinpointing the timing and magnitude of wind-blown input from the westerly and the polar easterly winds. Lake Steinbruvatnet (max. 2.6 m deep) is an exposed coastal basin. Located along the western coast of Sørkappøya at about 5 m a.s.l. and dammed by a bedrock ridge (ca. 8 m a.s.l.) to the West, and a wide uplifted beach ridge to the South and East, the basin is protected from direct storm surges. Moreover, the lake has no out- or inlet, limiting the potential for non-eolian catchment-derived minerogenic input. The data are organized per paper figure and table, per .txt files. Additional details may be found in the appended readme file. ABSTRACT: The Arctic is rapidly losing its sea ice cover while the region warms faster than anywhere else on Earth. As larger areas become ice-free for longer, winds strengthen and interact more with open waters. Ensuing higher waves also increase coastal erosion and flooding, threatening communities and releasing permafrost carbon. However, the future trajectory of these changes remains poorly understood as instrumental observations and geological archives remain rare and short. Here, we address this critical knowledge gap by presenting a continuous Holocene-length reconstruction of Arctic eolian activity using coastal lake sediments from Svalbard.
Exposed to both polar Easterlies and Westerly storm tracks, sheltered by a bedrock barrier, and subjected to little post-glacial uplift, our study site provides a stable baseline to assess Holocene changes in the dominant wind systems of the Barents Sea region. To do so with high precision, we rely on multiple independent lines of proxy evidence for wind-blown sediment input. Our reconstructions reveal quasi-cyclic summer wind maxima during regional cold periods, and challenge the view that a warmer and less icy future Arctic will be stormier. </p
