We generated seasonal displacement maps using DInSAR with ultrafine-beam Radarsat-2 data for the summers of 2013, 2015, and 2019 at Cape Bounty, Melville Island, and examined them in combination with a land-cover classification, meteorological data, topographic data, optical satellite imagery, and in situ measures of soil moisture, soil temperature, and depth to the frost table. Over the three years studied, displacement magnitudes (estimated uncertainty \u00b1 1 cm) of up to 10 cm per 48-day DInSAR stack were detected. However, generally, the displacement was far smaller (up to 4 cm). Surface displacement was found to be most extensive and of the greatest magnitude in low-lying, wet, and steeply sloping areas. The few areas where large vertical displacements (&gt;2.5 cm) were detected in multiple years were clustered in wet, low lying areas, on steep slopes or ridges, or close to the coast. DInSAR also captured the expansion of two medium-sized retrogressive thaw slumps (RTS), exhibiting widespread negative surface change in the slump floor.<\/jats:p>","DOI":"10.3390\/rs13132505","type":"journal-article","created":{"date-parts":[[2021,6,27]],"date-time":"2021-06-27T23:57:22Z","timestamp":1624838242000},"page":"2505","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Seasonal Surface Subsidence and Frost Heave Detected by C-Band DInSAR in a High Arctic Environment, Cape Bounty, Melville Island, Nunavut, Canada"],"prefix":"10.3390","volume":"13","author":[{"given":"Greg","family":"Robson","sequence":"first","affiliation":[{"name":"Department of Geography and Planning, Queen\u2019s University, Mackintosh-Corry Hall, Kingston, ON K7L 3N6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2109-9671","authenticated-orcid":false,"given":"Paul","family":"Treitz","sequence":"additional","affiliation":[{"name":"Department of Geography and Planning, Queen\u2019s University, Mackintosh-Corry Hall, Kingston, ON K7L 3N6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott F.","family":"Lamoureux","sequence":"additional","affiliation":[{"name":"Department of Geography and Planning, Queen\u2019s University, Mackintosh-Corry Hall, Kingston, ON K7L 3N6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin","family":"Murnaghan","sequence":"additional","affiliation":[{"name":"Canada Centre for Remote Sensing, 560 Rochester Street, Ottawa, ON K1A 0E4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8439-362X","authenticated-orcid":false,"given":"Brian","family":"Brisco","sequence":"additional","affiliation":[{"name":"Canada Centre for Remote Sensing, 560 Rochester Street, Ottawa, ON K1A 0E4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"340","DOI":"10.1038\/nclimate3262","article-title":"An observation-based constraint on permafrost loss as a function of global warming","volume":"7","author":"Chadburn","year":"2017","journal-title":"Nat.
