Thawing of ice-rich Yedoma results in lowering of surface elevations. Quantitative knowledge about surface elevation changes helps us to understand the freeze-thaw processes of the active layer and the potential degradation of Yedoma deposits. In this study, we use C-band Sentinel-1 InSAR measurements to map the elevation changes over ice-rich Yedoma uplands on Sobo-Sise Island, Lena Delta with frequent revisit observations (as short as six or 12 days). We observe significant seasonal thaw subsidence during summer months and heterogeneous inter-annual elevation changes from 2016\u201317. We also observe interesting patterns of stronger seasonal thaw subsidence on elevated flat Yedoma uplands by comparing to the surrounding Yedoma slopes. Inter-annual analyses from 2016\u201317 suggest that our observed positive surface elevation changes are likely caused by the delayed progression of the thaw season in 2017, associated with mean annual air temperature fluctuations.<\/jats:p>","DOI":"10.3390\/rs10071152","type":"journal-article","created":{"date-parts":[[2018,7,24]],"date-time":"2018-07-24T02:58:56Z","timestamp":1532401136000},"page":"1152","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Sentinel-1 InSAR Measurements of Elevation Changes over Yedoma Uplands on Sobo-Sise Island, Lena Delta"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9089-8587","authenticated-orcid":false,"given":"Jie","family":"Chen","sequence":"first","affiliation":[{"name":"Institute of Space and Earth Information Science, The Chinese University of Hong Kong, 999077 Hong Kong, China"},{"name":"Earth System Science Programme, Faculty of Science, The Chinese University of Hong Kong, 999077 Hong Kong, China"},{"name":"Shenzhen Research Institute, The Chinese University of Hong Kong, 518172 Shenzhen, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8298-8937","authenticated-orcid":false,"given":"Frank","family":"G\u00fcnther","sequence":"additional","affiliation":[{"name":"Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, 14473 Potsdam, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5895-2141","authenticated-orcid":false,"given":"Guido","family":"Grosse","sequence":"additional","affiliation":[{"name":"Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, 14473 Potsdam, Germany"},{"name":"Institute of Earth and Environmental Sciences, University of Potsdam, 14476 Potsdam, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9581-1337","authenticated-orcid":false,"given":"Lin","family":"Liu","sequence":"additional","affiliation":[{"name":"Earth System Science Programme, Faculty of Science, The Chinese University of Hong Kong, 999077 Hong Kong, China"}]},{"given":"Hui","family":"Lin","sequence":"additional","affiliation":[{"name":"Institute of Space and Earth Information Science, The Chinese University of Hong Kong, 999077 Hong Kong, China"},{"name":"Shenzhen Research Institute, The Chinese University of Hong Kong, 518172 Shenzhen, China"},{"name":"Department of Geography and Resource Management, The Chinese University of Hong Kong, 999077 Hong Kong, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1016\/j.quaint.2010.04.004","article-title":"Sedimentary characteristics and origin of the Late Pleistocene Ice Complex on north-east Siberian Arctic coastal lowlands and islands\u2014A review","volume":"241","author":"Schirrmeister","year":"2011","journal-title":"Quat.
