Micro-organic herbicide levels in river water for various sites within the Humber and Tweed catchments collected as part of the Land Ocean Interaction Study project (LOIS). The dataset contains data for Phenyl urea and Phenoxy acid herbicides, measured as 2,4-Dichlorophenoxyacetic...
1km resolution gridded potential evapotranspiration over Great Britain for the years 1961-2015. This dataset contains time series of two potential evapotranspiration variables. The first is potential evapotranspiration (PET) (mm/day) calculated using the Penman-Monteith...
Data comprise earthworm survival and weight change data after 28 days exposure to nanomaterials and reproduction data after 56 days exposure. Concentrations of zinc and silver in extracted soil pore water and ultra-filtered pore waters are reported as well as pH and...
Stream water discharge data from the UK Environmental Change Network (ECN) terrestrial sites. The data (stage and discharge) are collected by loggers at ECN's terrestrial sites (where a stream is present) using a standard protocol. They represent continuous 15-minutely...
The dataset captures the temporal and spatial variability of dilution factors (DFs) around the world using geographically referenced data sets at 0.5 degree resolution and includes long term annual and monthly DFs grids. The dilution factor (DF) dataset is composed...
This dataset consists of measures of topsoil mineralisable nitrogen (Mineral-N) from soils sampled from up to 256 1km squares across Great Britain in 2007. The Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample...
The dataset consists of solute concentrations (Potassium, Calcium, Magnesium, Iron, Sodium, Aluminium, Phosphate, Nitrate, Ammonium, Chlorine, Sulphate), also pH and suspended solids, in waters sampled from clear felled and standing Sitka spruce (Picea sitchensis) forest...
The data consists of plant physiological measurements from 15 sites located in the Conwy catchment (North Wales) and from 2 sites in North West England. Plant photosynthetic parameters for the maximum rate of carboxylation (Vcmax), the maximum rate of electron transport...
This dataset consists of autotrophic and heterotrophic soil respiration fluxes from peatland plateaus and thawing peatland plateaus and from burnt and unburnt forests from permafrost in subarctic Canada. Autotrophic and heterotrophic soil respiration fluxes (CO2) were...
This dataset consists of stock (length) data for linear features across Great Britain in 1998. The data are national estimates generated by analysing the sample data from 569 1km squares surveyed for the Countryside Survey long term monitoring project, then scaling...
This dataset consists of stock (length) data for linear features across Great Britain in 1984. The data are national estimates generated by analysing the sample data from 384 1km squares surveyed for the Countryside Survey long term monitoring project, then scaling...
This aggregation consists of datasets collected as part of the Isle of May long-term study (IMLOTS) on the ecology of six seabird species breeding on the Isle of May National Nature Reserve, off the East coast of Scotland: black-legged kittiwake (Rissa tridactyla),...
Standardised Precipitation Index (SPI) data for Integrated Hydrological Units (IHU) groups (Kral et al. [1]). SPI is a drought index based on the probability of precipitation for a given accumulation period as defined by McKee et al. [2]. SPI is calculated for different...
This dataset consists of fish species, fish length and fish weight from samples taken from small and medium catchments across Wales. Samples were collected in the summers and autumns of 2012 and 2013 using electrofishing. All the collected individuals were counted and...
This dataset consists of inshore surface water temperature (degrees C) data on Windermere. Data collection began in 1933, but it presented here from 1944 onwards. The data were initially collected by the Freshwater Biological Association (FBA), then by the Centre for...
This is a long-term monitoring dataset of surface temperature, surface oxygen, water clarity, water chemistry and phytoplankton chlorophyll a from weekly or fortnightly sampling at the North Basin of Windermere in Cumbria, England that began in 1945 for some variables....
A spatial approach was developed to interpret qualitatively expressed scenarios, and predict the probability and amount of change for 10 land-cover types across 127 sub-catchments in upland Wales. Existing data, which have a temporal coverage of 1998-2007, were used...
Topsoil moisture data - gravimetric moisture content (%). Data is representative of 0 - 15 cm soil depth. Cores from 1098 plots within 256 1km by 1km squares were measured in 1998 and 2614 plots within 591 1km x 1km squares were analysed in 2007 across Great Britain....
These data are macroinvertebrate composition and size in eight Welsh upland rivers with contrasting land-use, moorland and exotic conifer, in response to riparian deciduous leaf addition. Eight sampling reaches were chosen at two sites, Llyn Brianne (4 reaches) and...
This is a series of spatial and time series datasets including river networks, digital terrain model, soils, meteorology, river flow and hydro-chemistry.The Plynlimon research catchments lie within the headwaters of the River Severn and the River Wye in the uplands...
