  1. Functional annotation of Deschampsia antarctica genome

    Deschampsia antarctica É. Desv., the only indigenous grass species in the Antarctic Peninsula and the surrounding islands, has garnered significant garnered significant scientific attention due to its remarkable adaptations to the extreme polar environment. Given the importance of genomic adaptation in plants, particularly in extremophiles like D. antarctica, genome analysis and annotation is crucial for understanding its evolutionary significance and potential adaptive mechanisms. We conducted a comprehensive analysis to annotate D. antarctica genome and finally report the list of genes and its functional annotation.

  2. Carbon and nitrogen stable isotope ratios of benthic organisms in Marian Cove, Antarctica (2023-24)

    To trace the carbon sources in benthic ecosystem, benthic orgnisms such as ascidians and asteroidea were collected from the vicinity of King Sejong Station (pier and Daewang Rock). The stable isotope ratios of carbon and nitrogen were determined using an isotope ratio mass spectrometer coupled with and elemental analyzer (EA-IRMS).

  3. Daily carbon uptake rate of phytoplankton in the Marian Cove, Antarctica (2023-24)

    Field surveys were conducted to assess the carbon uptake rate of phytoplankton at 5 staions in Marian Cove, Antarctica during austral summer of 2023-24.

  1. 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. Should you have any inquiries or require further information, Dr. Choon-Ki Lee is available at cklee@kopri.re.kr and would be pleased to assist.

  2. 2D airglow intensity and mesopause temperature from MTM, 2023

    Two dimensional OH airglow intensity and temperature around 87km altitude at King Sejong Station, Antarctica. Studies of the atmospheric wave activities and mesopause temperature tendency in the mesosphere and lower thermosphere (MLT) over the southern high latitude.

  3. 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.
