title: Select benthic invertebrate and sediment data collected between 1969 and 2023 for an Ecological Risk-Based Approach to Facilitate Licensing Offshore Wind Development

description: The OneBenthic dataset contains records of benthic invertebrate assemblages and associated sediment particle size analyses (PSA) collected between 1969 and 2023 across the UK continental shelf and wider North Sea. It brings together harmonised information on macrofaunal abundance, biomass, and sediment composition derived from more than 50,000 seabed grab and core samples. For this study, a quality-controlled subset of 18,348 samples was used to generate spatial models of three ecological risk elements: benthic sensitivity (based on biological traits), biodiversity, and assemblage rarity. The dataset supports the development of ecological risk maps and an online decision-support tool to inform offshore wind farm licensing and marine spatial planning. Users should note that the dataset represents sedimentary habitats sampled by grabs and cores; results may not accurately describe rocky or hard-substrate environments and are not intended for navigational use.

The dataset was compiled from publicly available benthic invertebrate and sediment particle size analysis (PSA) data stored within the OneBenthic database, a cloud-based PostgreSQL repository maintained by the Centre for Environment, Fisheries and Aquaculture Science (CEFAS). The database integrates over 50,000 grab and core samples collected between 1969 and 2023 from UK shelf waters and neighbouring areas of the northeast Atlantic. Sampling methods followed established methodology, with the subset used here restricted to samples collected using a 0.1 m² grab or core and processed on a 1 millimetre sieve. Colonial taxa were included and recorded with a value of one. Raw abundance data were fourth-root transformed to down-weight highly abundant taxa, and samples less than 50 metres apart were removed to mitigate spatial autocorrelation. Biological traits information for taxa was sourced primarily from Clare et al. (2022), with trait data inferred for missing taxa using closely related genera or families. Samples were subject to quality control checks to ensure consistency in taxonomic nomenclature (via the World Register of Marine Species, WoRMS) and comparability of sampling methods. Environmental predictor variables used for modelling were obtained from Bio-ORACLE, gridded bathymetry data (GEBCO), and sediment composition layers from Mitchell et al. (2019). Spatial modelling of sensitivity, biodiversity, and assemblage rarity was carried out using Random Forest approaches with cross-validation to assess model robustness. Overall, the dataset is considered of high quality for large-scale spatial analyses of benthic assemblages in sedimentary habitats. Users should note that the dataset does not include rocky or hard-substrate habitats and is therefore not comprehensive for all benthic environments.

title: Daily soil moisture maps for the UK (2016-2023) at 2 km resolution

description: The data consist of daily maps of volumetric soil moisture predicted by a model based on a network of cosmic-ray neutron sensors (COSMOS-UK), the National River Flow Archive (NRFA) and remotely-sensed data. Maps cover the UK and Ireland at 2 km resolution in the Ordnance Survey National Grid (OSGB) projection. Maps are produced in near-real time, lagging by about one week. Data are available from early 2016 to 2023, on a daily basis. 

The model was calibrated on a network of cosmic-ray neutron sensors (COSMOS-UK) and remotely-sensed soil moisture data. A key parameter was estimated from the national-scale spatial pattern in the catchment response to rainfall seen in the National River Flow Archive (NRFA) data. Precipitation and humidity data to drive the model came from the Met Office High Resolution Numerical Weather Prediction model (NWP-UKV) which incorporates the C-band rainfall radar network. The maps have a variety of uses in hydrology and elsewhere, for example as inputs to ecosystem models of greenhouse gas exchange, where soil moisture affects numerous processes. The modelling was carried out as part of UK-SCAPE Virtual Survey Lab, and the NERC project "Detection and Attribution of Regional Emissions (DARE-UK)". There are some gaps in the time series of meteorological and remote sensing inputs, and data are unavailable for these days. The NRFA data are only available for Great Britain, so estimates in Ireland and continental Europe will be less accurate.
description: We developed a statistical model of soil moisture, calibrated on a network of cosmic-ray neutron sensors in the UK. We found that applying an exponentially-weighted moving-average filter effectively linearised the effect of precipitation, so we could form a simple linear model. With this, we integrated remotely-sensed soil moisture data. To extrapolate across the whole country, we inferred information on the soil water retention properties from daily water balance data from approximately 1200 catchments with wide coverage. 

We used a Bayesian approach to allow the uncertainty from the calibration at 40 sites to be propagated through the extrapolation on a grid covering the whole UK. The Met Office High Resolution Numerical Weather Prediction model (NWP-UKV), which incorporates the C-band rainfall radar network, provides very detailed data on the variation in precipitation which arises from the sporadic nature of rainfall events and interactions with orography in near-real time, to predict small-scale, short-term variation in soil moisture.

title: Maps showing risk and potential impacts of ozone on sugarcane production in south-central Brazil, 2010-2014

description: This dataset contains gridded model outputs of the predicted risk to C4 sugarcane production across south central Brazil for 2010-2014.  The outputs are given as production in kg m-2 yr-1, percentage of control production (%) and production losses in kg yr-1 and Tg yr-1. The spatial resolution is 1.25 x 1.875 degrees. Three different levels of ozone susceptibility (low, moderate or high) and two distinct threshold values of phytotoxic ozone dose (0 and 2 nmol m-2 s-1) were considered. 
description: These data were produced using the Joint UK Land earth simulator (JULES v5.6) run on JASMIN. The sugarcane was represented in JULES by using the C4 plant functional type. The input modelled O3 exposure data were simulated using the Earth System Model (UKESM1) for the period 2000 to 2014. JULES was used to calculate annual yields with or without consideration of ozone susceptibility for a 10-year period across south-central Brazil. The spatially explicit model outputs were compared to control model output to calculate the proportional decline and absolute impacts.

title: Meteorology, soil physics, and eddy covariance measurements of carbon dioxide, energy, and water exchange from a distributed network of sites across England and Wales, 2018-2023

description: This dataset contains time series observations of surface-atmosphere exchanges of carbon, water, and energy, as well as supporting micrometeorological, soil physics, and vegetation measurements.
Data have been obtained at ten eddy covariance (EC) flux observation sites across England and Wales. Sites were active for different time periods between 2018 and 2023.

Flux data include net ecosystem carbon dioxide exchange (NEE), sensible heat (H), and latent heat (LE). Examples of ancillary and vegetation data include measurements of air temperature, relative humidity, barometric pressure, wind speed and direction, components of radiation, soil heat flux, soil temperature and moisture, precipitation, water table depth, biomass, leaf area index (LAI), and canopy height. 

This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.
description: Eddy covariance (EC) and micrometeorological observations were made using open-path EC systems.

Turbulent flux densities were calculated from the raw EC data using the EddyPro® Flux Calculation Software.

Quality Control of EC data involved removal of statistical outliers and tests that theoretical requirements for the successful application of the EC technique were not violated significantly.

title: Seasonal activity and behavioural responses to artificial light at night in migratory and non-migratory sparrows (Dataset).

description: Data files in support of the published research evaluating the effect of artificial light at night (ALAN) pollution on migratory and non-migratory sparrows. The study included captive experiments repeated across three seasons (spring, summer and autumn) to compare changes in individual activity and behaviour of two nocturnal migrant sparrows, Gambel’s white-crowned (Zonotrichia leucophrys gambelli), white-throated sparrows (Z. albicolis), and a non-migrant house sparrow (Passer domesticus) exposed to dark control and light treatments. Birds were individually video recorded in captive indoor trials conducted in spring, summer, and autumn seasons, and tested under a range of ALAN intensities (0.15, 0.5, 1.5 and 10 lux) relative to dark control (&lt;0.01 lux). Dataset includes raw data files from the video recorded activity and behavioural trials as well as mass and food consumption data for each bird and annotated R scripts for the data analysis.
