title: Riverine nitrogen gas production by anaerobic ammonium oxidation across contrasting geologies

description: This dataset contains anaerobic ammonium oxidation (anammox) and denitrification activity of riverine sediments in the Hampshire Avon catchment (UK). Nine rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. Data were obtained via laboratory incubations (potential data) and direct, field-based measurements (in situ data) in summer 2013. Also included are chemical parameters determined in porewaters prior to in situ rate measurements.
description: All data were generated by the authors. As chemical data were generated, checks were made to ensure accuracy (certified reference materials) and precision (repeat measurements) were within accepted tolerance limits. We also ensured measured values fit within those of calibration standards and, if necessary, re-analysed samples diluted to fall within the calibration range. For data generated via mass spectrometry, beam areas of all measured mass-to-charge ratios were corrected for drift offline using control standards. All data were checked to ensure reported values were above the detection limit of the method. All calculations were checked for errors before data was accepted.

title: A time series of wind speed & direction, air temperature, humidity and atmospheric pressure measured during seasonal campaigns at six tributaries of Hampshire River Avon from 2013 to 2014

description: The dataset contain meteorological time series encompassing wind dynamics, and air temperature and relative humidity that were collected in the proximity of the streambed of selected riverine sites within the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, greensand, chalk) and associated river morphology were investigated. Data were obtained from field-based measurements in seasonal campaigns conducted between spring 2013 and winter 2014.
description: All data were generated by the authors. As time series containing physical parameters were generated, checks were made to ensure that each instrument was properly calibrated and serviced prior to each campaign to keep accuracy and precision within the manufacturer tolerances. Furthermore, the time series were screened for outliers caused by unsuitable meteorological conditions and contamination by the users during concurrent activities on site. All data were checked to ensure reported values were above the detection limit of the respective sensors.

title: Coastal Biodiversity and Ecosystem Service Sustainability (CBESS) projected area of vegetation in saltmarsh habitats

description: The dataset contains estimates of the projected area of vegetation derived from the analysis of side-on photographs through the vegetation canopy and recorded for survey quadrats at six UK saltmarsh sites. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England, each of these sites consisted of a saltmarsh area and adjacent mudflat area. Each site comprised 22 quadrats in the vegetated area of salt marsh. A calibrated camera was used to photograph through a 600 x 200mm section of vegetation against a red background. Calibrated images were then classified into vegetation and background classes and parameters of vegetation density in the horizontal were computed.

This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme - is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme.
description: The method followed that of Möller (2006). Side-on photography was undertaken in the field using a frame to ensure consistent geometry and a calibrated Fuji Finepix XP30 camera. Photographs were rectified using Matlab and exported in TIFF format to Erdas Imagine for classification. A 20-class unsupervised classification was performed followed by manual attribution of classes into "background" and vegetation". The binary image files were then analysed in Matlab based on pixel sizes derived from the camera calibration procedure against a chequerboard background. Further methodological details are contained in the supporting document.

title: Continuous measurements of rainfall (2002-2007) [LOCAR]

description: Continuous measurements of rainfall from the Frome Piddle; Pang Lambourn and Tern catchments, recorded between 2002 and 2007. Continuous recording rain gauges were installed at six sites in these catchments to record 15 minute rainfall data for differing periods at the varying sites. The instruments were installed as part of the NERC funded Lowland Catchment Research (LOCAR) Programme to provide comparable baseline rainfall data across the LOCAR catchments.
description: The rainfall data were measured using an automatic tipping bucket rain gauge. The gauge consisted of a funnel that collected and channelled the precipitation into a small seesaw-like container. After a pre-set amount of precipitation fell, the bucket tipped, dumping the collected water. The tips were converted into 15 minute rainfall data values and stored on the connected logger. The Catchment Service Team in each catchment was responsible for installing, maintaining and downloading the loggers on the rain gauges on a regular basis. The data are raw and have not been quality controlled.

title: Calcium and magnesium concentrations in plants used as human and animal foods derived from global literature

description: The data comprise collated data on calcium and magnesium (milligrams per kilogram dry mass) in plants used as human and animal food (including fruit, vegetables, grasses, nuts and seeds) from global literature published between 1982 and 2019. Where reported strontium values are also included. Each data point is referenced.
description: Data were collated from published global literature and converted to milligrams per kilogram dry mass. If the water content had already been accounted for in the published data, the water_content_% column contains n/a. Where water content was not already accounted for in the data, the percentage water content is provided and was applied to the data. The data were filtered and the ranges checked; outlier values were checked for accuracy. Each data point is referenced and a full list of references is provided in the supporting document.

title: Land-use and climate change for 1.5 and 2.0 degrees centigrade warming scenarios (JULES land surface model)

description: This dataset includes six sets of model output from JULES/IMOGEN simulations. Each set includes output from JULES (the Joint UK Land Environment Simulator) run with 34 climate change patterns from 2000-2099. The outputs provide carbon stocks and variables related to the surface energy budget to understand the implications of land-based climate mitigation.
description: JULES is a community model available for use after registering on the JULES repository (https://code.metoffice.gov.uk/trac/jules). The model version used here was r9448, which is a branch of vn4.8 with updates to represent harvesting of bioenergy crops and for running IMOGEN in inverse mode (using specified temperature pathways instead of specified concentration pathways). To use JULES-IMOGEN, patterns from 34 GCMs are needed, which are available from https://doi.org/10.5285/343885af-0f5e-4062-88e1-a9e612f77779. JULES requires a series of input files (initial conditions, model grid, CO2 concentration, land-use per grid cell, soil parameters, etc.). These are provided in the “ancillary_files” directory of the dataset. 

JULES can be run with a system called Rose, which stores model settings. We also include an excel spreadsheet with the suites used for the Harper et al. (2018) paper. The suites are available from https://code.metoffice.gov.uk/trac/roses-u (registration required).

The original IMAGE land use data is available from https://data.knmi.nl/datasets?q=PBL. We used v17 land fractions from SSP2-SPA0-RCP1.9 and SSP2-SPA2-RCP2.6. These were regridded from half degree to the N48 resolution using ESMF Regrid patch interpolation method from NCAR Command Language (http://ncl.ucar.edu/Document/Functions/ESMF/ESMF_regrid.shtml). The actual fractions used in the simulations are in both the input and output files.

For further details, see Harper et al. (https://doi.org/10.1038/s41467-018-05340-z). The experimental design is the same as in Comyn-Platt et al. (https://doi.org/10.1038/s41561-018-0174-9), which also has a linked dataset for the historical period.

title: Ammonia measurements from passive samplers at Ballynahone Bog field site, Northern Ireland, 2020

description: This dataset consists of ammonia (NH3) measurements from a set of ALPHA (Adapted Low-cost Passive High Absorption) sampler sites at Ballynahone National Nature Reserve, a designated Area of Special Scientific Interest (ASSI), Special Area of Conservation (SAC) and Ramsar (wetland of international importance designated under the Ramsar Convention) site in Northern Ireland. The park is an ammonia sensitive peatland ecosystem managed locally by Ulster Wildlife Trust (UWT). The data were originally collected due to concern that Ballynahone Bog may be adversely affected by NH3 emissions arising from local livestock installations.
description: This data was produced from samplers collected by UWT and analysed by UK CEH.  Analysis data was processed using the UK CEH AAGA data handling system.

title: Diatom data from the South Fork McKenzie River in Oregon, USA after a wildfire event, 2021 to 2022

description: Periphyton data consists of diatom scrubs sampled in a range of riffle and pool habitats including diatom taxa counts (identified to genus level) and computed autotrophic index (ratio of the organic mass per cm2 to mass (microgram) of chlorophyll a) as well as site characterisation data.

The data were collected from the South Fork McKenzie river, Oregon, USA in September of 2021 and February 2022 following the Holiday Farm wildfire in Autumn 2020. Samples were collected from a restored and unrestored reach of the South Fork McKenzie River with a view to quantifying differences in periphyton response to wildfire in the restored vs. unrestored river reaches.

The study was conducted by the University of Nottingham, with data collected by partners from The US Forest Service, Portland State University, Washington State University and Colorado State University. Funding for the work was received from the Natural Environment Research Council.
description: Periphyton was sampled in riffles and pools in the restored and unrestored reach of South Fork McKenzie River using standard methods (Baird, Eaton & Rice, 2017 ISBN: 9780875532875; Kelly et al., 1998 https://doi.org/10.1023/A:1008033201227). A toothbrush was used to scrub the periphyton off five randomly selected cobbles. The cobbles were rinsed with distilled water and the resultant liquid was composited them into a single sample, which was split into three subsamples. One subsample was preserved in 37% formalin for diatom composition analysis, while two unpreserved subsamples were analysed for chlorophyll a (Chl a) and ash-free dry mass (AFDM). At least 500 diatom valves were counted from each sample and identified to genus level.

title: Temporal variation in temperature and light availability in the Hampshire Avon, United Kingdom  [Macronutrient Cycling]

description: The dataset contains measurements of temperature (°C) and light availability (Lux) in rivers in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. The stream sites monitored were chosen to reflect a gradient of base flow index. Data were obtained via direct, field-based measurements every 15 minutes from February 2013 to (max) December 2014 with sensors tethered to the bed of the river at each site. 
description: All data were generated by the authors. The data comprise measurements of temperature (°C) and light (Lux) made by Onset HOBO Pendant Temperature/Light UA-002-64 data loggers (Onset Computer Corporation, 470 MacArthur Blvd., Bourne, MA 02532 USA) tethered to the bed of 6 streams, all tributaries of the Hampshire Avon. The loggers were calibrated by the manufacturer. Temperature: ±0.53°C from 0 to 50°C. Time: ± 1 minute per month at 25°C. Light: 200 - 1200 nm, 60% response 500 - 1100 nm, 100% response 900 nm. For full details, see HOBO Pendant Temperature/Light Data Logger (UA-002-xx) Manual: www.onsetcomp.com. Breaks in the continuous data occur due to removal of sensors from the river for data downloads or loss/malfunction of loggers.

title: Hampshire Avon: soil temperature and water content data from three sub-catchments

description: The dataset contains measurements of soil temperature and volumetric water content from plots in agricultural grasslands in the Hampshire Avon catchment (UK) from late-2013 to September 2015. Manipulations of soil temperature were made at three orthogonal experiments in three sub-catchments of contrasting geology (chalk, clay and greensand) between May and September 2015.
description: All data were generated by the authors. Prior to field deployment, all sensors were checked to ensure accuracy and precision were within accepted tolerance limits. Post hoc analysis of measured temperature and volumetric water content values were subject to a vigorous quality checking procedure, removing data when sensors produced unreliable data or failed.

title: Plant-pollinator interactions database for construction of potential networks

description: Plant-pollinator interactions database derived from biological recording data, unpublished experimental data and published interactions in books and papers.  The database covers all recorded interactions for bees, hoverflies and butterflies in mainland GB.  Interactions were inferred from biological recording metadata by algorithmically screening for text matching a valid scientific or vernacular plant name (or a widely used synonym or abbreviation of either), followed by manual data cleaning.  These data were compiled for the construction of multiple potential plant-pollinator networks in combination with plant and pollinator occurrence data.
description: Biological recording data were obtained from the Bees, Wasps and Ants Recording Society (BWARS), Butterflies for the New Millennium (BNM, Asher 1997) and Hoverfly Recording Scheme (HRS), with interactions recorded as incidental metadata submitted alongside occurrence records. Pollinator biological records with associated metadata were algorithmically screened for text matching a valid scientific or vernacular plant name (or a widely used synonym or abbreviation of either).  In most cases, such matches record the visitation of a flower by a pollinating insect.  However, there are other reasons for a valid match in the comments field, including descriptions of local habitat (e.g. 'English oak woodland'), pollinator behaviour (e.g. 'flying near blackthorn hedge') or sampling methods (e.g. 'swept from Arrhenathrum eliatus sward').  In order to exclude these, all plant species producing a match were screened according whether they produce flowers which are known to be visited by insects and whether such visits are likely to result in beneficial pollen transfer (i.e. the plant is primarily entomophilic).  These criteria excluded the majority of trees and grasses, which are likely to derive from habitat descriptions or interactions other than flower visits (e.g. honeydew feeding).  Even though some primarily wind-pollinated grass flowers are known to be visited by certain pollinators, their impact on pollen transfer is likely to be very slight in temperate climates (Clifford 1964; Adams et al. 1981).  The data contains only plant species not defined as 'casuals' in PLANTATT ('casual is a plant that is present only as populations which fail to persist in the wild for periods of more than approximately five years' Hill et al. 2004).

title: Methane and carbon dioxide fluxes from a seasonal wetland in the Okavango Delta, Botswana, 2018-2020

description: The dataset consists of a continuous time series of heat (latent and sensible) and trace gas (carbon dioxide and methane) fluxes obtained by eddy-covariance, gas concentrations and some ancillary meteorological data (e.g. air temperature, relative humidity, pressure, photosynthetically active radiation, total incoming radiation, wind speed and direction). The data were collected at Nxaraga, on the south edge of Chief’s Island (19°32'53''S; 23°10'45"E), in the seasonally flooded area of the Okavango Delta, Botswana, for the purpose of quantifying greenhouse gas fluxes from seasonal floodplains. The data is reported at half-hourly interval for the measurement period 01/01/2018 to 31/12/2020. Missing data were caused by instrumentation downtime and are reported as -9999.
description: The eddy-covariance instrumentation consisted of a Campbell Scientific IRGASON and a LI-COR 7700 open-path methane (CH4) analyser. A Vaisala WXT520 weather station recorded air temperature, pressure, relative humidity, wind speed and wind direction. Total solar radiation and photosynthetically active radiation (PAR) were measured by a Skye Instruments pyranometer (model SKS1110) and quantum detector (model SKP215), respectively. A Campbell Scientific CR3000 datalogger logged all sensors (sampling rate of 10 Hz for the EC variables and 10-s interval for the meteorological parameters).
The instrumentation was installed by Dr Carole Helfter; monthly maintenance and data collection visits were effected by Dr Mangaliso Gondwe. The raw data were processed into half-hourly fluxes using the EddyPro software package version 7.0.6 and quality controlled by Dr Helfter.

title: Extensive vegetation and soil surveys from multiple sites in boreal forests of subarctic Canada, 2013-2014

description: The dataset contains a stratified survey of ecological and soil states at sites where fine scale patterns of covariation between vegetation and edaphic characteristics were recorded. Key data collection included leaf area index, moss and organic matter thickness, surface and deeper soil moisture. 

Data were collected at sites in the Yukon (2013) and Northwest Territories (2014), Canada.
description: Tree canopy leaf area index (LAITree) was determined using a Nikon D5000 DSLR camera with a Sigma EX 4.5 1:2.8 DC HSM hemispherical lens. Nine photographs were taken at different locations 1 m above each plot and processed with CAN-EYE software. 

Understory LAI (LAIU) was measured using a LI-COR LAI2000 Plant Canopy Analyser (LI-COR, Lincoln, USA). One measurement was taken above the understory canopy with a 90 degree field of view cap and four measurements were taken below the understory canopy at the four corners of a 20 x 20 cm square at the centre of each plot.

Moss thickness was determined by carefully removing a section of moss and organic material from the ground with a serrated knife while avoiding compression. Moss thickness was measured as the distance from the surface of the living moss to the point at which dead moss (fibric material) became decomposed to a state that its structure was no longer discernible.

title: Susceptibility of native Scots pine (Pinus sylvestris) to Dothistroma septosporum following natural inoculation at Torrs Warren, Galloway 2013-2015

description: Data collected from a progeny-provenance trial to examine Dothistroma needle blight (DNB) infection in native Scottish populations of Scots pine.

Data include multiple infection assessments and height measurements and a single chlorophyll fluorescence measurement, record of branching and a defoliation assessment for each tree in the trial plus measurements of individual infected needles (length of lesions, number of lesions per needle, length of needle).

The trial was transplanted from CEH Edinburgh in April 2013 to Torrs Warren forest, Galloway, a site known to be infected with Dothistroma needle blight (DNB), caused by Dothistroma septosporum. The experiment ran until September 2015 with infection assessments (% estimated DNB severity per tree) performed roughly every 6 months from September 2013.

description: There are eight Scottish Scots pine populations (Ballochbuie, Blackwood of Rannoch, Beinn Eighe, Coille Coire Chuilc, Glen Affric, Glen Loy, Glen Tanar, Rothiemurcus) with four families per population each consisting of six individuals = total 192 trees. The trees were grown from seed collected at each site, and germinated in spring 2007 at CEH Edinburgh. They were transplanted in 2013 when they were six years old. The transplantation site at Torrs Warren was adjacent to stands of Corsican and lodgepole pine which were infected with Dothistroma needle blight.

The trees were transplanted in 6 litre pots and were staked to the ground at 0.5 m spacing. A guard row of Scots pine trees (also at 0.5 m spacing) was placed around the edge of the trial to minimise edge effects.

Weeding, to cut back brambles and bracken surrounding the trees, was performed annually in the summer.

The trial consists of six randomised blocks each containing one individual per family.

The data were collected as part of the PROTREE project (funded jointly by a grant from BBSRC, Defra, ESRC, the Forestry Commission, NERC and the Scottish Government, under the Tree Health and Plant Biosecurity Initiative) and Annika Perry's PhD studentship which was funded by NERC Centre for Ecology & Hydrology and Forest Research.
