  • The datasets contain insect numbers, plant biomass, successful attacks of parasitoids, and behavioural response of parasitoids. The data have been sampled as part of the NERC project NE/N001672/1 "Effects of artificial light on multi-trophic population dynamics". The data are based on direct observations of insects and plants in field and laboratory experiments testing for the impact of different intensities of artificial light at night on an experimental insect food web with control (no light), and white LED light with 0.1,1,5,10,20,50,100 lux. Data collection was done in a field site, and controlled temperature room at Penryn Campus of University of Exeter, Penryn, UK. The field experiment was set up on 29th July 2016 and ran for nine weeks, while the additional experiments were conducted between summer 2016 and spring 2018.

  • [This dataset is embargoed until February 22, 2022]. Half-hourly data from eight eddy covariance towers deployed in the Sevilleta Refuge (New Mexico, USA). The main sensors deployed were sonic anemometer, relative humidity sensor and carbon dioxide concentration sensor . They were deployed and maintained by Fabio Boschetti and Andrew Cunliffe (University of Exeter). The data were collected to test the new design of eddy covariance towers and investigate the spatial variability of fluxes. Data were collected from 2018-11-01 to 2019-11-01. The data contains very few small gaps due to maintenance. Half-hourly data were gap-filled using code published on GitHub. The research was funded through NERC grant reference NE/R00062X/1 - "Do dryland ecosystems control variability and recent trends in the land CO2 sink?"

  • Benthic stable isotope (carbon and oxygen) data from IODP Site U1445. Generated by Yasmin Bokhari-Friberg, supervisied by Kate Littler and Pallavi Anand.

  • Non-contact Atomic Force Microscopy images (NC-AFM) of surface nanobubbles on the carbonate mineral dolomite. Since surface nanobubbles were first imaged in 2000, they have been of growing interest to research due to their long lived properties, with reported lifetimes as long as several hours. Images of nanobubbles were produced under water, collector and depressant conditions using the air water supersaturation method. These are the first images of surface nanobubbles on dolomite. Surface nanobubbles could play a part in the processing of dolomite via froth flotation. These images lay a foundation for future analysis of the effect of nanobubbles in flotation.

  • This dataset comprises a record of benthic foraminifera count data from three cores that were analysed to assess down core changes in foraminifera abundance from the Paluma Shoals reef complex, Halifax Bay, central Great Barrier Reef, Australia; cores OPS-PC2, OPS-C-PC1 and OPS-D-PC1. The site/core names relate to the sites described in the following paper: Morgan KM, Perry CT, Smithers SG, Daniell JJ and Johnson JA (2016) Extensive reef development within the “mesophotic” nearshore Great Barrier Reef: Evidence for intra-regional variations in coral resilience. Scientific Reports 6:29616. DOI: 10.1038/srep29616.

  • Description of peatland sites included in the compilation of carbon accumulation rates, including resolution (high, low), interpolation (yes/no), contributor name, country, lon, lat, peatland type, dominant plant type, no. of dates used in the last millenium carbon accumulation rate calculation, and problems with the data. Peatland sites at northern hemisphere high and mid latitudes (260), tropical (30) and southern hemisphere high latitudes (7 sites).

  • This document is the drillers log of strata encountered during site investigation work. The log was made in the field during drilling at Prees, Shropshire on 8th to 10th January 2020. The log includes basic information on lithology and drilling equipment used and depths of the individual core runs.

  • This dataset comprises raw carbon, oxygen and hydrogen stable isotope data on water (precipitation and terrestrial) and plant cellulose from Empodisma-dominated peatlands throughout New Zealand. This data has been published in two open access papers: Amesbury, M. J., Charman, D. J., Newnham, R. M., Loader, N. J., Goodrich, J. P., Royles, J., Campbell, D. I., Roland, T. P. and Gallego-Sala, A. V. 2015. Carbon stable isotopes as a palaeoclimate proxy in vascular plant dominated peatlands. Geochimica et Cosmochimica Acta 164, 161-174. Amesbury, M. J., Charman, D. J., Newnham, R. M., Loader, N. J., Goodrich, J. P., Royles, J., Campbell, D. I., Keller, E. D., Baisden, W. T., Roland, T. P. and Gallego-Sala, A. V. 2015. Can oxygen stable isotopes be used to track precipitation moisture source in vascular plant dominated peatlands? Earth and Planetary Science Letters 430, 149-159.

  • We report sedimentary coatings and fish teeth neodymium isotope values – tracers for water-mass mixing – from deep-water International Ocean Discovery Program (IODP) Site U1438 (4.7 km water depth) in the Philippine Sea, northwest Pacific Ocean. The time period encompasses the last 20 million years.

  • The dataset contains model output from an agricultural land use model at kilometre scale resolution over Great Britain (GB) for four different climate and policy scenarios. Specifically, arable area is modelled for with or without a climate tipping point (standard (medium emissions scenario SRES-A1B) climate change vs Atlantic Meridional Overturning Circulation (AMOC) collapse) and with or without widespread irrigation use for farmers from 2000 to 2089.
