Recent Data

  1. Next Generation Sequencing data for targeting bacterial 16S rRNA in Cambridge Bay in 2018

    The aim of this data is to investigate the effects of warming or precipitation on the community and abundance of bacterial 16S rRNA in Cambridge Bay during the growing season. The data was collected monthly from soils between June and September 2018 and created using the Illumina Miseq platform.

  2. Antarctic ice mass change (2003-2020) jointly estimated by satellite gravimetry and altimetry

    This dataset complements the work of Kim et al. (2024), providing gridded ice mass change data for Antarctica, with a resolution of 27km, from January 2003 to December 2020. The dataset was estimated using the constrained linear deconvolution (CLD) method developed by Kim et al. (2022), which integrates satellite gravimetry (GRACE) and altimetry data. The data sampling aligns with the timeframe of the GRACE and GRACE-FO observations. Further information about this dataset can be found in the following publications: B-H Kim, K-W Seo, C-K Lee, J-S Kim, J Chen, and C R Wilson. "Antarctic ice mass change (2003-2016) jointly estimated by satellite gravimetry and altimetry" Journal of Geophysical Research: Solid Earth, 2022. B-H Kim et al.

  3. Data on soil methane flux, physicochemical and microbial properties during the 2023 growing season (July - September) in Council, Alaska wet tundra

    * Research objective: To understand the synergistic legacy effect of increased snow depth during winter and vascular plant species on growing season methane emissions * Data description: Soil samples were frozen at -20°C after collection. Soil physicochemical properties were analyzed in the laboratory after completely thawing soil at 4°C. The soil physicochemical pro perties include: - Water content (WC) (%) - Organic matter content (OC) (%) - pH - Ammonium (NH4) (μg-N gdrysoil-1) - Total Nitrogen (TN) (%) - Total Carbon (TC) (%) - Carbon/Nitrogen ratio (C/N) - Nitrate (NO3) (μg-N gdrysoil-1) - Dissolved Organic Carbon (DOC) (μg gOC-1) - Soil Thaw depth (cm) - Soil Redox potential (mV) Soil methane flux data was collected via a closed static chamber method. The headspace gas samples were transferred to pre-evacuated gas vials every 15min for 45min. The gas samples were brought to the laboratory and analyzed via GC-FID. Soil samples for microbial analysis were separated and kept at -80°C until analysis. The soil microbial properties include: - mcrA (log10 mcrA copy number gOC-1) - pmoA (log10 pmoA copy number gOC-1)

  3. New Catalogue of Thwaites Glacier Subglacial Lakes and Their Activity Revealed by CryoSat-2 Altimetry

    This dataset unveils a newly compiled catalogue of active subglacial lakes beneath the Thwaites Glacier in West Antarctica, as detected through the CryoSat-2 satellite radar altimetry. The catalogue meticulously details each lake, outlining its boundaries, area, and elevation changes along with their 95% confidence intervals for precise scientific referencing. For citation purposes, please refer to the following article: B-H Kim, C-K Lee*, K-W Seo, W S Lee, and J-W Park. "New Catalogue of Thwaites Glacier Subglacial Lakes and Their Activity Revealed by CryoSat-2 Altimetry," currently under revision for the Journal of Geophysical Research: Earth Surface.
