title: Dataset for manuscript : Stable carbon isotopes reveal soil-stream DIC linkages in contrasting headwater catchments

description: Large CO2 evasion to the atmosphere occurs as dissolved inorganic carbon (DIC) is transported from soils to streams. While this physical process has been the focus of multiple studies, less is known about the underlying biogeochemical transformations that accompany this transfer of C from soils to streams. Here we used patterns in stream water and groundwater δ13C-DIC values within three headwater catchments with contrasting land cover to identify the sources and processes regulating DIC during its transport. 

The study was conducted within three headwater catchments representing contrasting land covers. Two of the catchments, Svartberget (SVB) and Degerö Stormyr (DEG), are located in northern Sweden within the Svartberget Experimental Forests (64°14′N, 19°46′E). The third catchment, Skogaryd (SKOG), is located in south-western Sweden within the Skogaryd Research Catchment (58°23′N, 12°09′E).

title: Data on variability in k600 and CO2/CH4 emissions within and across streams of different stream order
title: Data on variability in k600 and CO2/CH4 emissions within and across streams of different stream order
title: ADV.k600.CO2.CH4

description: The study based to this dataset explored the variability in k600 and subsequent CO2 and CH4 emission rates within and across streams of different stream order (SO). We conducted, for the first time in streams, direct turbulence measurements using an acoustic Doppler velocimeter (ADV) to determine the spatial variability in k600 across a variety of scales with a consistent methodology. 

This study was conducted in an ∼80 km2 fourth-order catchment in south-central Sweden (; 59.803279°N, 15.167283°E). The catchment consists of 84.3% forest; 10% wetlands, marshes, fens and bogs; 5.1% lakes; 0.5% agriculture; and 0.06% habitation. The sampled sites were distributed along a hydrological chain of streams and lakes with streams ranging from SO1 to SO4. The average transect water velocity was multiplied by the cross-section area to obtain an average Q for the stream reach. Water temperature, electrical conductivity, and dissolved oxygen were measured in situ with an HQ40d Portable Multiparameter Meter (HACH), and pH was measured in the lab from water samples on a Metrohm 744 pH meter. We conducted sampling campaigns on 3 occasions: August 2015, April 2016, and June 2016.

title: Data on how repeated disturbances affect microbial ecosystem resistance in natural lake bacterioplankton communities

description: Data associated with the manuscript "Disturbance history can increase functional stability in the face of both repeated disturbances of the same type and new disturbances" by Renes et al. 2020.

Climate change is expected to increase the incidences of extremes in environmental conditions. To investigate how repeated disturbances affect microbial ecosystem resistance, natural lake bacterioplankton communities were subjected to repeated temperature disturbances of two intensities (25 °C and 35 °C), and subsequently to an acidification event. We measured functional parameters (bacterial production, abundance, extracellular enzyme activities) and community composition parameters (richness, evenness, niche width) and found that, compared to undisturbed control communities, the 35 °C treatment was strongly affected in all parameters, while the 25 °C treatment did not significantly differ from the control. Interestingly, exposure to multiple temperature disturbances caused gradually increasing stability in the 35 °C treatment in some parameters, while others parameters showed the opposite, indicating that the choice of parameters can strongly affect the outcome of a study. The acidification event did not lead to stronger changes in community structure, but functional resistance of bacterial production towards acidification in the 35 °C treatments increased. This indicates that functional resistance in response to a novel disturbance can be increased by previous exposure to another disturbance, suggesting similarity in stress tolerance mechanisms for both disturbances. These results highlight the need for understanding function- and disturbance-specific responses, since general responses are likely to be unpredictable.

title: Data on Selective adsorption of terrestrial dissolved organic matter to inorganic surfaces along a boreal inland water continuum
title: Data on Selective adsorption of terrestrial dissolved organic matter to inorganic surfaces along a boreal inland water continuum

description: Different processes contribute to the loss or transformation of dissolved organic matter (DOM) and change DOM concentration and composition systematically along the inland water continuum. Substantial efforts have been made to estimate the importance of microbial and photochemical degradation for DOM concentration and composition and, to some extent, also DOM losses by flocculation, whereas the significance of DOM adsorption to inorganic surfaces has received less attention. Hence, knowledge on the possible extent of adsorption, its effect on DOM loads and composition and on where along the aquatic continuum it might be important is currently limited or lacking altogether. Here, we experimentally determine DOM adsorption onto mineral particles in freshwater ecosystems covering a water residence time gradient in boreal landscape Sweden. We hypothesized that adsorption would gradually decrease with increasing water residence time, but actually found that DOM is highly susceptible to adsorption throughout the aquatic continuum. Mass spectrometry and fluorescence analysis on DOM suggest that freshly produced aquatic DOM is less susceptible to adsorption than more terrestrial material. Moreover, the percentage DOM adsorbed in the experiments greatly exceeds the actual adsorption taking place in boreal inland waters across all studied systems. These results illustrate the potential impact of mineral erosion, for example as a result of agriculture, mining or forestry practices, on the availability, transport and composition of organic carbon in inland waters.

We collected water samples from 30 sites distributed throughout Sweden and studied the effect of adsorption to mineral particles on dissolved organic matter composition. The data set belongs to a manuscript accepted by the Journal of Geophysical Research - Biogeosciences.

The data set contains fluorescence and mass spectrometry data from all 30 sites before and after adsorption:
- corrected EEMs of 180 samples (30 samples, triplicates, before and after adsorption treatment)
- PARAFAC model of the 180 EEMs
- compiled mass spectrometry data (30 samples, before and after adsorption treatment)

The dataset was originally published in DiVA and moved to SND in 2024.

title: Data from Geant4 calculations of average gamma heating from selected cases of used light water reactor nuclear fuel assemblies in a KBS-3 type deep geological repository

description: Monte Carlo calculations, using the Geant4 framework version 10.02 [1], of energy deposition from gamma radiation emitted from light water reator fuel assemblies in a KBS-3 type deep geological repository for used nuclear fuel has been performed. Selected cases of boiling and pressurized reactor fuel assemblies from the "SKB-50" set of fuel assemblies were used; "BWR1", "BWR6" and "PWR8" [2]. An isotropic source of gamma-rays with energies of 444, 662, 723 and 1274 keV, depending of the case, were distributed homogeneously in the intersection of a (mid-)plane perpendicular to the canister central axis with all the fuel rods in all fuel assemblies in the canister. The average energy deposition in a 3-dimensional (x,y,z) mesh with 1 cm resolution was calculated per emitted gamma particle. This dataset contains the resulting meshed energy deposition data.

Description of files:
- The gzip compressed tar file contains comma-separated-values (CSV) files with the data "mesh x position [cm], mesh y position [cm], mesh z position [cm], average energy deposition per emitted gamma [MeV]" supplied on each row. The name of the CSV file specifies the fuel assembly id from the SKB-50 set of fuel assemblies as well as the energy of the emitted gamma radiation.
- The txt-file contains the SHA-256 checksum of the gzip compressed tar file.

title: Land reflection seismic, hydrogeological and magnetic study of an area prone to quick-clay landslides in southwest Sweden

description: Quick-clay landslides are common geohazards in Nordic countries and Canada. The presence of potential quick clays is confirmed using geotechnical investigations, but near-surface geophysical methods, such as seismic and resistivity surveys, can also help identifying coarse-grained materials associated to the development of quick clays. 

We present the results of four reflection seismic profiles next to the Göta River in Sweden, along which many quick-clay landslide scars exist. An extensive coarse-grained layer exists in the sedimentary sequence and is interpreted and modeled in a regional context. Hydrological modeling of the coarse-grained layer is performed. Magnetic data are also studied within this investigation.

Four reflection seismic profiles collected in 2013 (line 5 has two parts, cabled geophones and wireless stations).
description: Jordskred av kvicklera är vanliga "geohazards" i Norden och Kanada. Närvaron av potentiella kvickleror bekräftas med hjälp av geotekniska undersökningar, men geofysiska metoder i närheten av ytan, såsom seismiska och resistivitetsundersökningar, kan också bidra till att identifiera grovkornigt material i samband med utvecklingen av kvickleror. 

Vi presenterar resultaten av fyra reflexions-seismiska profiler bredvid Göta älv i Sverige, längs vilka många jordskred av kvicklera finns. Ett omfattande grovkornigt lager finns i sedimentärsekvensen och tolkas och modelleras i ett regionalt sammanhang. Hydrologisk modellering av det grovkorniga skiktet utförs. Magnetiska data studeras också inom denna undersökning.
