Chemical composition of freshwater samples from sites in Northern England. Measurements of pH, dissolved major ions (Na, Mg, K, Ca, Cl, NO3, SO4), dissolved organic carbon (DOC), dissolved Al, Fe(II) and total Fe, and measurements of Al, Fe(II) and total Fe on samples following dialysis.

The dataset comprises of plant species recorded from plots located within the Moor House National Nature Reserve, with associated plot information such as slope and aspect, also peat depth. The sampling strategy was based on a grid, using 2 x 2 metre square plots. The majority of the plots were recorded in the summers of 2008 and 2009 by surveyors employed by the Centre for Ecology & Hydrology.

This dataset contains the concentration of eleven antibiotics (trimethoprim, oxytetracycline, ciprofloxacin, azithromycin, cefotaxime, doxycycline, sulfamethoxazole, erythromycin, clarithromycin, ofloxacin, norfloxacin), three decongestants (naphazoline, oxymetazoline, xylometazoline) and the antiviral drug oseltamivir's active metabolite, oseltamivir carboxylate, measured at 21 locations within the River Thames catchment in England. The measurements were taken weekly during November 2009, once in March 2010 and once in May 2011, with the aim to quantify pharmaceutical usage during the influenza pandemic of 2009 and how this compares to inter-pandemic drug use. River samples were acquired by grab samples in glass jars and analysed by liquid chromatography tandem mass spectrometry (LC MS). Two wastewater treatment plants (WWTPs) in southern England (Benson and Oxford) were also sampled during the peak of the second wave of the 2009 influenza A[H1N1]pdm09 pandemic (10-11 November 2009) and on 15 May 2011 using an automated sampler set to acquired hourly (time proportional) samples from the influent and effluent of the WWTPs. The WWTPs are the source for all the drugs found in the river, hence, these were studied to understand the differential fate of the analytes in the two very different WWTPs. Flows for the WWTP and River sampling locations are presented for each of the sampling times to allow for determining hourly loads for the WWTP and daily loads for the river.

Soil moisture and Electrical Resistivity Tomography (ERT) measurements within the top metre of soil at Church Field, Chimney Meadow National Nature Reserve. Church Field lies on a clay lens which overlies surrounding sand and gravel soils. Apart from the A and B horizons, the clay was found to be fairly homogenous down to the maximum depth of 1.1m of the access pit. On the 1:250,000 Soil Map of South East England the location falls into the soils category 832 Kelmscott Association which comprise mostly permeable fine loamy soils over limestone gravel and variably affected by groundwater and with some risk of flooding. However, on the more detailed 1:25,000 scale Sand and Gravel Resources Map of the Thames Valley the clay lens is depicted as Oxford Clay substrate without sand and gravel cover, surrounded by sand and gravel terraces cropping out at the surface.

The dataset contains information on the species identity and frequency of all insect-flower interactions recorded in 10 birch (Betula spp.) woodland fragments surveyed in 2009 (May-August). The data were collected in two transects (50 x 2m; 15m apart and at least 50m from the woodland edge) randomly situated prior to the onset of flowering in the centre of each wood. Five of the woodland sites were disturbed by cattle grazing, while five were undisturbed. Landowners confirmed that livestock had been absent for at least 70-100 years in undisturbed sites. Where livestock were present, cattle grazing was light to moderate (e.g. 2007: mean = 8.4 cattle ha-1) and long term (mean = 33 years). The dataset comprises 13 columns, 2002 rows and is 218 KB. It gives the site name, geographic coordinates, whether it was disturbed by cattle grazing or not, the wind speed and temperature at time of sampling, the date of sampling, and the identity of the insect and plants interacting (binomial name or recognisable taxonomic unit).

This dataset contains greenhouse gas profile measurements from the Amazon Integrated Carbon Analysis (AMAZONICA) project. AMAZONICA was an UK-Brasil Consortium funded by NERC (Natural Environmental Reasearch Council, UK) which aimed to quantify the carbon balance of the Amazon Basin and its associated contribution to global atmospheric change, to apportion and understand the processes contributing to the net Basin-wide flux observed and, to allow improved assessments of the likely role of the Amazon Basin in contributing and/or alleviating future planetary change. Data were collected and collated by the AMAZONICA team in the UK and Brazil and were deposited at BADC before the end of the project (expected end 2012 - mid 2013).

ABACUS (Arctic Biosphere Atmosphere Coupling at Multiple Scales) is funded by a grant (NE/D005795/1) from the Natural Environment Research Council (NERC) International Polar Year (IPY) Programme. The ABACUS research project is a major, linked programme of plant and soil studies, atmospheric measurements, aircraft and satellite observations, and modelling, to improve our understanding of the response of the arctic terrestrial biosphere to climate change. The data collected includes root measurements and isotope ratios of plants, CH4 emissions of soils, measurements of Carbon and water exchanges between soils/vegetation and the atmosphere at fine scales (resolution of ~1m), and at scales of ~100m, records of snow depth, soil moisture and climate, and aircraft images of the land surface and profiles of CH4. Observations and measurements of the carbon budget and the carbon exchange between soil, plants and atmosphere in terrestrial Arctic ecosystems were collected at 4 field sites with different ecosystems near Abisko (Northern Sweden) and Petsikko/Kevo (Northern Finland) between 2007 and 2009. Plant data has so far been archived at the BADC.

The Coastal Air Pollution (CAP) field campaigns in 2009 and 2010 (CAP-2009 and CAP-2010 respectively) sought to investigate the impact of local meteorology on coastal air quality and the structure and evolution of the coastal boundary layer. This dataset consists of surface, tower and airbourne measurements of atmospheric chemistry and vertical wind profiles from the Coastal Air Pollution (CAP) field campaign, led by Dr. Claire Reeves (University of East Anglia, UEA). Airborne measurements were made by instrumentation on board the Facility for Airborne Atmospheric Measurements's (FAAM) BAE 146 aircraft, with surface and tower measurements from the Weybourne Atmospheric Observatory (WAO) and the Facility for Ground-based Atmsopheric Measurements's (FGAM) 1290Mhz mobile wind profiling radar providing vertical profiles of winds, signal to noise ratios and spectral width data. These data were used to investigate the impact of local meteorology on coastal air quality and the structure and evolution of the coastal boundary layer. The objectives of the campaign was to: a) characterise the chemical composition of the air above and around WAO in various meteorological conditions to determine how representative the WAO observations are of the coastal region and of the air-mass origin (esp. in the case of maritime/Arctic air); b) determine the local flow patterns that can be established around WAO which may influence the redistribution of pollutants and to aid future identification of such patterns with the more limited vertical data that is routinely collected at WAO; c) identify patterns that decouple polluted layers from the surface; d) characterise the off-shore pollution sources (ship emissions, emissions from off-shore gas platforms) which impact measurements at WAO under maritime conditions; and, e) provide test cases for the one-dimensional MISTRA model of vertical profiles of trace components in the boundary layer and lower free troposphere, especially providing information about vertical exchange.

The Flood Action Team (FLoAT) project is intended to collate a variety of data collected during the June and July 2007 Flood events in the UK (e.g. Tewkesbury event in 2007). This project is funded by the Natural Environment Research Council (NERC) - project Ref. R8/H12/69 - through the Flood Risk for Extreme Events (FREE) NERC directed mode programme. Aerial images of the Tewkesbury area, which include the river Severn and the river Avon, were collected during the flood events of summer 2007.
