Quantifying Basal Roughness and Internal Layer Continuity Index of Ice Sheets by an Integrated Means with Radar Data and Deep Learning

Xueyuan Tang, Kun Luo, Sheng Dong, Zidong Zhang, Bo Sun
2022 Remote Sensing  
Using this method, we demonstrate the ice-penetrating radar data processing and compare the imaging and calculation of the radar profiles from Dome A to Zhongshan Station, East Antarctica.  ...  from their radar-extracted internal structure.  ...  Second, we calculate the subglacial basal roughness and ILCI based on the airborne radar data along the traverse from Zhongshan Station to Dome A in Princess Elizabeth Land, East Antarctica, and compare  ...

Removal of 'strip noise' in radio-echo sounding data using combined wavelet and 2-D DFT filtering

Bangbing Wang, Bo Sun, Jiaxin Wang, Jamin Greenbaum, Jingxue Guo, Laura Lindzey, Xiangbin Cui, Duncan A. Young, Donald D. Blankenship, Martin J. Siegert
2019 Annals of Glaciology  
For example, strip noise can result in reduced power from the bed, affecting the quality of ice thickness measurements and the characterization of subglacial conditions.  ...  However, RES data are often subject to 'strip noise', caused by internal instrument noise and interference, and/or external environmental interference, which can hamper measurement and interpretation.  ...  We thank Ettore Biondi and four anonymous referees for providing constructive reviews of our work, which improved the paper considerably.  ...

High-resolution reconstruction of atmospheric CO2 concentrations during the last interglacial based on the EDC ice core

Lucas Borges da Silva
2022
Hence, high-resolution reconstructions of CO2 are usually limited to a specific window of time of the last 800 thousand years (800 ka).  ...  As enigmatic as the plateau is the last glacial inception when CO2 suddenly drops from interglacial levels and resumes its coupling with Antarctic temperature.  ...  Acknowledgements The support of my family and peers carried me in the personal voyage of manbirthing this document. I would like to warmly thank  ...
