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 acid, 4-(4-Chloro-O-tolyloxy) butyric acid, 4-Chloro-O-tolyloxyacetic acid, Chlorotoluron dissolved, Diuron dissolved, Isoproturon dissolved, Linuron dissolved, Mecoprop dissolved. Phenyl urea herbicide data is available for twelve sites in the Humber catchment within 1994 to 1995 and 1994 to 1997 and for three sites on the Tweed catchment within 1995. Phenoxy acid herbicide data is available for six sites (S1, U3, N4, W5 and O6) over the period December 1994 to September 1995, for 7 sites (S2, D7, A8, C9, D10, T11 and O12) over the period December 1994 to February 1997 and 3 sites (TW13, TW14 and TW15) over the period January 1995 to September 1995. Attempts were made to sample the sites at weekly intervals. However sampling was halted for short periods when it was not possible to process the samples quickly. Linuron dissolved was only measured from April 1994 - October 1994. Samples were collected in chromic acid-washed 1 litre glass bottles. Herbicide levels were concentrated before being measured using High Performance Liquid Chromatography for Phenyl urea herbicides and Gas Chromatography for Phenoxy acid herbicides. Until November 1994, analysis was completed by the York University and the Institute for Freshwater Ecology, Wareham, laboratories. From December 1994 onwards the samples were dispatched to the Institute for Hydrology, Wallingford, for extraction and analyses.

Data comprises patterns of diversity in a below-ground community of microarthropods (mites and collembola), measured during a nutrient (calcium and nitrogen) manipulation experiment, located at the Natural Environment Research Council (NERC) Soil Biodiversity Site in Sourhope, Scotland, UK. Data collected include abundance of microarthropods, and also microbial biomass carbon, soil respiration, wet pH using de-ionised water, soil loss on ignition, dry root biomass, total carbon and nitrogen content of soil and roots and soil moisture content. The data were collected as a component of the NERC Soil Biodiversity Programme, established in 1999 and centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute)'s farm at Sourhope in the Scottish Borders. During this time, the site was monitored to assess changes in aboveground biomass production (productivity), species composition and relative abundance (diversity).

This dataset consists of a 1km resolution raster version of the Land Cover Map 2000 for Northern Ireland. Each 1km pixel represents the dominant aggregate class across the 1km area. The aggregate classes are aggregations of the target classes, broadly representing Broad Habitats (see below). The dataset is part of a series of data products produced by the Centre for Ecology & Hydrology known as LCM2000. LCM2000 is a parcel-based thematic classification of satellite image data covering the entire United Kingdom. LCM2000 is derived from a computer classification of satellite scenes obtained mainly from Landsat, IRS and SPOT sensors and also incorporates information derived from other ancillary datasets. LCM2000 was classified using a nomenclature corresponding to the Joint Nature Conservation Committee (JNCC) Broad Habitats, which encompasses the entire range of UK habitats. In addition, it recorded further detail where possible. The series of LCM2000 products includes vector and raster formats, with a number of different versions containing varying levels of detail and at different spatial resolutions.

The Ancient Biomolecules Initiative is a Natural Environment Research Council programme exploring the biomolecular record of past life which is entombed in archaeological and geological deposits. The findings have applications in archaeology, anthropology, forensic science, research into the past climates and oil exploration. This resource consists of a series of leaflets in PDF format which describe the key findings of the Ancient Biomolecules Initiative.

Triazine, organophosphate and pyrethroid (TOP) pesticide data from river water collected at various sites within the Humber catchment area as part of the Land Ocean Interaction Study project (LOIS).. Water samples were collected weekly and during storm periods between 1994 and 1996. The unfiltered samples were extracted on the day of collection using solid-phase-extraction (SPE), the SPE cartridges stored overnight at 4 degreesC and then transported to the Institute of Freshwater Ecology (IFE), Wareham for elution, drying and Gas Chromatography (GC) analysis. Pesticides measured were Atrazine, Cyanazin, Desmetryn, Fenitrothion, HCH gamma, Malathion, Parathion, Permethrin, Prometryn, Simazine, Terbutryn. The sampling and extraction of the pesticides was carried out by the LOIS team at York University and the elution and sample preparation for GC analysis was done at IFE.

These data comprise arbuscular mycorrhizal (AM) fungi diversity data from Sourhope field experiment site. AM fungi are biotrophic symbionts colonizing the majority of land plants, and are of major importance in plant nutrient supply. Using the terminal restriction fragment length polymorphism (T-RFLP) strategy, the diversity of AM fungi was assessed in 89 roots of three grass species (Agrostis capillaris, Festuca rubra, Poa pratensis) that co-occurred in the same plots of the Sourhope field experiment. The impact of different soil amendments (nitrogen, lime, nitrogen and lime) and insecticide application on AM fungal community was also recorded. Data were collected during a project funded under the NERC Soil Biodiversity Programme, established in 1999 and centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute) farm at Sourhope in the Scottish Borders (Grid reference: NT 8545 1963). During the experiment, the site was monitored to assess changes in above-ground biomass production (productivity), species composition and relative abundance (diversity).

Continuous measurements of temperature, pH, conductivity and dissolved oxygen from river water at ten sites located within the rivers Swale, Derwent, Aire, Calder, Trent, Ouse and Nidd. Part of the Land Ocean Interaction Study (LOIS) project. Hydrolab H20 water quality monitors were installed at ten sites and used to log water temperature, pH, conductivity and dissolved oxygen between 1994 and 1997. Data were collected continuously at 30 minute intervals (for periods of variable lengths depending on site) between 1994 and 1997. Data were collected using Hydrolab DataSonde 3 continuous monitoring units. Hydrolabs at River Nidd (Hunsingore) and the River Swale (Crakehill) were suspended from trees. The other hydrolabs were located in large steel pipes running from the bank into the rivers which allowed the flow of water over the probes but offered a high degree of safety from damage by vandals and large water borne objects. The units on the Trent and the Ouse at Skelton were fitted with stirrers, as the probes were prone to fouling by the high levels of suspended solids often encountered in these rivers during spate conditions. The deployment of the units and the collection of data were carried out by members of the field sampling team at York University, as part of the Land Ocean Interaction Study (LOIS).

This dataset consists of a 1km resolution raster version of the Land Cover Map 2000 for Great Britain. The raster consists of 27 bands. Within each band, each 1km pixel represents a percentage cover value for one of 27 target (or 'sub') classes, roughly representing Broad Habitats. [Note subclass codes are numbered 0-26 but the raster bands are numbered 1-27; therefore each band relates to the one below it in the subclass code list (e.g. band 1 = unclassified, 2 = Sea/Estuary, 3 = inland water, etc] The dataset is part of a series of data products produced by the Centre for Ecology & Hydrology known as LCM2000.
