  • A measure of the extent and complexity of riprian vegetation upstream of chalkstream sites derived from Light Detection and Ranging (LiDAR) data for 15 discrete chalkstreams distributed along a white chalk geology extending from Dorset in the south west, through Wiltshire, to Hampshire in the north east. For each site there is an estimate of the minimum, maximum, mean and standard deviation height of vegetation along the banks for a range of distances upstream from the sampling location. Information on the extent and complexity of riparian vegetation upstream of chalkstream sites were used to better understand the relationships between in-stream biological communities and catchment and riparian land use. Stream sites surveyed represented a sample of chalkstreams across a gradient of catchment land cover intensification from catchments dominated by extensive calcareous grassland and woodland to those dominated by arable and improved grasslands. LiDAR data were obtained from the Environment Agency in April 2014. This dataset was created as part of work package 3.1 of the Wessex Biodiversity & Ecosystem Service Sustainability (BESS) project.

  • This presentation on the UKCCSRC Call 2 project Quantifying Residual and Dissolution Trapping in the CO2CRC Otway Injection Site was presented at the UKCCSRC Edinburgh Biannual Meeting, 15.09.2016. Grant number: UKCCSRC-C2-204.

  • This MS Excel dataset contains tephra depth and age data from ocean drilling expeditions around Japan. IODP, ODP and DSDP shipboard core description records were examined for mentions of volcanic ash, tephra etc., according to criteria described in Mahony et al. 2014. Data are from shipboard visual core descriptions of ocean drilling expeditions located within a few hundred km of Japan. Cores without published age-depth data are not included in this dataset. The expeditions occurred between 1973 (DSDP 31) to 2013 (IODP 346). Tephra layers are dated as being deposited between 0.003-18.5 Ma. This data will be of interest to volcanologists or anyone interested in the location of volcanic ash layers within IODP cores.

  • This poster on the UKCCSRC Call 2 project, Multiscale characterization of CO2 storage in the United Kingdom, was presented at the Cranfield Biannual, 21.04.15. Grant number: UKCCSRC-C2-197.

  • The data consists of raw data on measured carbon dioxide (CO2) and nitrous oxide concentration (N2O) concentrations from intact soil topsoil (0-15 cm) and subsoil cores (85-100 cm) to added carbon, nitrogen and phosphorus. Four land uses (Bog, acid grassland, improved grassland and arable field) in North Wales were selected for this study with three replicates each. Intact soil cores were taken in January and February in 2014. The data consists of three datasets. The first dataset contains the measured CO2 concentration that was measured from intact topsoil cores (0-15 cm) as a result of carbon, nitrogen and phosphorus additions form a pilot study. For the pilot study intact topsoil cores were taken in November and December in 2013 from three sites. a Podzol, a coniferous forest soil and a grassland soil. These sites were not in the Conwy Catchment. The pilot study results were used to inform the experimental setup for the main experiment. The data from the main experiment, measured carbon dioxide (CO2) and nitrous oxide concentration (N2O), are reported in the second dataset for intact topsoil and subsoil cores. The third dataset contains nitrogen mineralization data from the intact soil cores that were used as control cores and did not receive any carbon or nutrient additions. The dataset contains measurements on soil nitrate, ammonium and total nitrogen mineralization rates in milligrammes of nitrogen per gramme of dry weight or per gramme of organic matter content. In both the experimental datasets, the weight of the soil cores at field capacity (in grammes) was reported and weight loss was adjusted by adding an artificial rain water solution. The incubation time (in minutes), the measured CO2 and N2O concentrations (in part per million = ppm) were recorded at the beginning and the end of the incubation. Total soil dry weight per soil core (in grammes) and the total weight of soil organic matter (loss on ignition, in grammes) are reported. The data were collected to calculate production of Measurements were undertaken by staff from the Centre for Ecology & Hydrology. The data were collected to link plant and soil nutrients to aboveground and belowground ecosystem processes to incorporate relevant parameters into the Joint UK Land Environment Simulator (JULES) model. This data was collected for the NERC project 'The Multi-Scale Response of Water quality, Biodiversity and Carbon Sequestration to Coupled Macronutrient Cycling from Source to Sea' (NE/J011991/1). The project is also referred to as Turf2Surf. Full details about this dataset can be found at https://doi.org/10.5285/0c17a041-8852-4800-9c04-2ab2dd858837

  • Files contain heavy mineral (HM) and framework petrography data for samples taken from sediments across Northern China, from Tarim in the west to Ordos in central north China. The data come from river, loess, silt and sand sediments from deserts, the Chinese Loess Plateau, major rivers and alluvial fans of ages spanning the Cenozoic to modern. Data are grouped into tables with sample details and data types. Each file pertains to a given paper: Stevens et al., 2013a: doi:10.1016/j.quascirev.2012.11.032 Stevens et al., 2013b: doi:10.1016/j.quascirev.2013.10.014 Bird et al., 2015: doi:10.1016/j.palaeo.2015.06.024 Nie et al., 2015: doi:10.1038/ncomms9511 Rittner et al., 2016: doi:10.1016/j.epsl.2015.12.036 Supplementary Material - Contains Hf, Nd and Sr isotopic data from modern, Pleistocene and Pliocene samples from surface and sediment section sediments from Northern China.
