  • These data are NERC-funded but not held by the EIDC. These data are archived in the SAFE repository, hosted by Zenodo. This dataset contains calculated greenhouse gas fluxes and associated parameters from 56 static chambers that were installed within the Stability of Altered Forest Ecosystems (SAFE) landscape in Malaysian Borneo. Of the chosen ‘fragment’ in the SAFE design, all chambers were put in the 10 ha fragments. Four chambers each were placed in each of the two 10 ha plots in Logged Fragmented Forest (LFE), Fragment B, and Fragment E resulting in 8 per site. Additionally 12 chambers were installed in a 7-year old oil palm plantation, 8 in a young (2-year) old oil palm and 8 in a 12 – year old oil palm plantations. All 56 chambers were sampled for greenhouse gases (methane, nitrous oxide and carbon dioxide soil respiration) every two months over a two-year period from January 2015 to November 2016, resulting in 12 measurement occasions for each of the chambers. Other environmental parameters were measured during the time of chamber enclosure as possible explanatory variables for correlation with recorded greenhouse gas fluxes including soil and air temperature, soil moisture, soil mineral N (nitrate and ammonium).

  • These data are NERC-funded but not held by the EIDC. These data are archived in the SAFE repository, hosted by Zenodo. This dataset contains calculated greenhouse gas fluxes and associated parameters from three transects of static chambers that were set up from oil palm into riparian forests in the SAFE landscape in Malaysian Borneo, Sabah. A total of 48 chambers were installed in two transects of 6 x 3 chambers and one transect of 4 x 3 chambers. Soil greenhouse gases (methane, nitrous oxide and carbon dioxide) were measured every two months for one year (Nov 2016 until Nov 2017) resulting in 7 measurement occasions. Other environmental parameters were measured during the time of chamber enclosure as possible explanatory variables for correlation with recorded greenhouse gas fluxes including soil and air temperature, soil moisture, soil mineral N (nitrate (NO3) and ammonium (NH4)). In addition, water samples were taken from the stream and analysed for NO3, NH4, pH, temperature, total dissolved solids, conductivity and greenhouse gases using the headspace method.

  • This dataset contains calculated terrestrial fluxes of methane and nitrous oxide using static chambers from the Sodankylä region of Northern Finland across both forest and wetland ecosystems. Measurements were carried out during growing season 2012 in two measurement campaigns (Summer: 12th July - 2nd August; Autumn: 22nd September - 14th October) using 60 static chambers (21 within the forest and 39 within the wetland). Fluxes were measured on approximately 2 day intervals resulting in a total of 10 measurements for all chambers during the summer campaign, and 7 for the forest and 8 for the wetland chambers during the autumn campaign. In addition to fluxes, auxiliary measurements include soil temperature, water table depth (wetland only), soil moisture (forest only) and soil respiration. The data was collected as part of the MAMM project (Methane and other greenhouse gases in the Arctic: Measurements, process studies and Modelling, http://arp.arctic.ac.uk/projects/) funded by the UK Natural Environment Research Council (grant NE/I029293/1) involving partners from CEH and the Finnish Meteorological Institute (Climate Change Research, FI-00101 Helsinki, Finland).

  • These data are NERC-funded but not held by the EIDC. These data are archived in the SAFE repository, hosted by Zenodo. This dataset contains results from a laboratory study that was carried out with soil taken from logged tropical forests and nearby oil palm plantations of different ages in Malaysian Borneo, Sabah within the SAFE project landscape. The soils were from: Logged Fragmented Forest (LFE) pH 6, Fragment E (FE) pH 6, ~7 year old oil palm plantation (OP7) pH 4.5 , small riparian area below OP7 (RR), pH 5.8, ~2 year old row of oil palm (OP2) pH 4.5. The soils were collected in Nov 2016, from the top 0-10 cm. During the laboratory incubation all cores were sampled for greenhouse gases (methane, nitrous oxide and carbon dioxide) as well as nitric oxide (NO). Other environmental parameters were measured at the same time as possible explanatory variables for correlation with recorded greenhouse gas and nitric oxide fluxes including soil and air temperature, soil moisture, soil mineral N (nitrate and ammonium) and gene transcript abundance.

  • These data are from an investigation of the effects of biochar application to soil, on soil greenhouse gas emissions and N transformations within the soil. Biochar is a carbon rich substance which is being advocated as a climate mitigation tool to increase carbon sequestration and reduce nitrous oxide emissions. The data were collected during a 15N pool dilution incubation to investigate the nitrogen transformations within biochar-amended soil following the addition of 15N-labelled ammonium nitrate. Analyses included 15N content of nitrous oxide and 15N content of soil. The N transformations were then modelled using a model for calculating nitrogen fluxes in soil using 15N tracing (FLUAZ model).

  • This dataset contains concentrations of dissolved organic carbon, inorganic carbon, CO2, CH4 and N2O in the Black Burn stream which drains Auchencorth Moss peatland in South East Scotland. Concentrations and fluxes have been measured within the Black Burn on an approximately weekly to fortnightly basis from approximately 2006 to present (see https://doi.org/10.5285/3f0820a7-a8c8-4dd7-a058-8db79ba9c7fe). Concentrations in this dataset are from a series of new sites, upstream of the long-term sampling record, adjacent to an area of drains blocked by Scottish Natural Heritage. Measurements began during the drain blocking. Data was collected initially as part of a masters project for University of Edinburgh through Scotland's Rural College and continued by the Centre for Ecology & Hydrology.

  • This dataset contains vegetation survey data, and nitrate and ammonium concentrations, nitrification and mineralisation rates, microbial biomass and carbon and nitrogen stock data from soils taken from an experiment based at Winklebury Hill, UK. The vegetation survey comprises total species percentage cover and species richness data from four 50 cm by 50 cm quadrats. Net ecosystem carbon dioxide exchange, photosynthesis and respiration data were measured with an Infra-red Gas Analyser (IRGA); methane, carbon dioxide and nitrous oxide data were measured using gas chromatography; nitrate and ammonium from soil samples extracted with potassium chloride; carbon and nitrogen from soils extracted with water; and carbon and nitrogen stocks measured through combustion analysis. The experiment used seeds and plug plants to create different plant communities on the bare chalk on Winklebury Hill and tested the resulting carbon and nutrient cycling rates and compared these to the characteristics of different plant functional groups. The experiment ran from 2013 to 2015 and this dataset contains data from 2015 only. This experiment was part of the Wessex BESS project, a six-year (2011-2017) project aimed at understanding how biodiversity underpins the ecosystem functions and services that landscapes provide.

  • Data collected during field and laboratory experiments to investigate the long-term effects of biochar application to soil on greenhouse gas emissions in a bioenergy plantation (Miscanthus X. giganteus). Analysis included monitoring of greenhouse gas emissions (carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)), soil physical (bulk density and soil moisture ) and soil chemical analyses (total carbon (C) and nitrogen (N), extractable ammonium and nitrate). Biochar was applied to plots in a bioenergy plantation and emissions of CO2, CH4 and N2O were measured over a 2 year period. In addition a laboratory incubation experiment was conducted on soil taken from the Miscanthus field amended with field-incubated biochar to assess the effect on greenhouse gas emissions. Biochar is a carbon rich substances which is being advocated as a climate mitigation tool to increase carbon sequestration and reduce nitrous oxide emissions.
