  • [THIS DATASET HAS BEEN WITHDRAWN]. This dataset contains vegetation survey data from an upland heath site in the Clocaenog Forest. Vegetation was surveyed in the experimental plots at the Climoor site in 1998, 1999, 2000, 2002, 2003, 2007, 2008, 2009, 2010, 2011 and 2012. The vegetation at the site is a typical UK upland heathland, dominated by Calluna vulgaris, with Vaccinium myrtillus and Empetrum nigrum also being present in the vegetation understory. In each year, measurements were taken at a time period of maximum growth, which was late August/early September. This was done by pin point methodology, and data includes both pin hits as well as measurements converted into plant biomass. Individual species can be examined, as well as the different components of the higher plants (i.e. leaf, stem, flower).

  • The dataset comprises hourly water temperature data of an experimental mesocosm facility as well as air temperatures from beginning of July to end of September 2022. The experiment aimed to investigate the effect of different nutrient regimes on Taste and Odour issues. Mesocosms were filled with reservoir water and water temperature was measured by platinum resistance thermometers (PRT) shaded by a plastic cover, sited around mid-depth, radially offset by 30 cm from the mesocosm's side wall and logged by a Campbell Scientific Data Logger. Air temperature was measured at a weather station within the mesocosm compound (Vaisala weather transmitter WXT520) at around 2.7m height.

  • The dataset consists of pH, Loss on ignition (Soil organic matter) measurements and soil group information taken from soil samples from plots in 103 woodland sites surveyed across Great Britain in 1971 and again over the growing seasons of 2000, 2002 and 2003 (referred to as '2001 survey'), using exactly the same field methods. Data were collected under projects managed by The Nature Conservancy (in 1971) and the Centre for Ecology & Hydrology (in 2001).

  • Dataset contains Terrestrial laser scanner (TLS) and CT scan data collected during fieldwork on a small gravel-bed river. TLS data show the river bed surface topography collected at five intervals between September 2014 and October 2018. CT scan data show the 3D structure of sections of the river bed. CT data has been processed to segment the images into gravel grains and fine-grained matrix.

  • This datasets contains Electrical Resistivity Tomography surveys taken in the Makutapora Basin, Central Tanzania, using an AGI SuperSting R8 (STING) resistivity meter. Survey geometry, parameters and coordinates are also included. Full details about this dataset can be found at https://doi.org/10.5285/1998da32-a978-41a4-8a66-81df1e625cca

  • This data set comprises two years of data (2016 and 2017) from one trial (Hucking, Kent, UK) and one year (2017) from a second trial (Hartshorne, Derbyshire, UK). Data was collected on tree traits (tree height, shoot length, tree provenance), abundance of foliar insect herbivores (gallers, leaf manipulators and leaf miners) and leaf damage by oak powdery mildew, a foliar fungal pathogen. Data was collected from plots differing in tree diversity (provenance and species diversity).

  • River water alkalinity, chloride-ion, conductivity, pH and nutrients data from the Frome Piddle; Pang Lambourn and Tern catchments, recorded between 2003 and 2006. River water samples were collected fortnightly at twenty three sites within these catchments and analysed for Alkalinity pH 4.5, Ammonia, Chloride-ion, Conductivity 20 deg C, Nitrate, pH, Phosphorus soluble reactive (SRP), Silicate reactive dissolved (SRD) and Sulphate. The samples were collected as part of the NERC funded Lowland Catchment Research (LOCAR) Programme to provide comparable baseline river water chemistry data across the LOCAR catchments.

  • This dataset contains the areas affected by landslides triggered by Typhoon Parma in the area of Itogon (Benguet, Philippines) between the 2nd and 5th October 2009. The polygons were mapped using Google Earth imagery dated 31 December 2003 for pre-event and images and 31 December 2009 for post-event images. The area has an extension of 150 km2. Full details about this dataset can be found at https://doi.org/10.5285/2e15dbd2-71c3-4e86-aa90-6029d37bd417

  • This dataset contains the concentrations of Ni, Cu, Zn, Cd and Pb, extracted from four soils, using the chemical extractants: 0.43 M HNO3, 0.43 M CH3COOH, 1 M CaCl2 and 0.05 M Na2H2EDTA (MExt mg/kg). The concentrations of isotopically exchangeable (labile) Ni, Cu, Zn, Cd and Pb (EValue mg/kg) are also given. Additionally, the concentrations of isotopically exchangeable soil metal, measured when the soils when suspended in each of the above extractants (EExt mg/kg), are presented. Full details about this dataset can be found at https://doi.org/10.5285/4ecdb4b3-3af6-4c92-abbb-20a330be398b

  • Data on concentrations of dissolved PAHs and dissolved organic carbon (DOC) in 20 water samples collected from the River Wyre at five sites between Marshaw Wyre, one of the two headwaters of the River Wyre, and Garstang from August 2010 to June 2011. As typical for this region, the upland reaches of this river drain peatland areas, resulting in a relatively high dissolved organic carbon content. PAHs were measured as freely dissolved PAHs (i.e. freely dissolved in the water phase) and total dissolved PAHs (the sum of freely dissolved and those associated with DOC) and the fractions associated with DOC have been estimated from these two. Where possible, the DOC-water partition coefficient of the PAHs, calculated from the concentrations determined, is given as well. The data is presented as one table and two supporting files containing metadata. Full details about this dataset can be found at https://doi.org/10.5285/24200DBA-D0F4-4BE4-AE6F-2C6EC1147FA4
