The ability of these warm waters to reach glacier termini is strongly controlled by fjord bathymetry, which was unmapped for the majority of Greenland\u2019s fjords until recently. In response to the need for bathymetric measurements in previously uncharted areas, we developed two companion methods to infer fjord bathymetry using icebergs as depth sounders. The main premise of our methods centers around the idea that deep-drafted icebergs will become stranded in shallow water such that estimates of iceberg surface elevation can be used to infer draft, and thus water depth, under the assumption of hydrostatic equilibrium. When and where available, surface elevations of icebergs stranded on bathymetric highs were extracted from digital elevation models (DEMs) and converted to estimates of iceberg draft. To expand the spatial coverage of our inferred water depths beyond the DEM footprints, we used the DEMs to construct characteristic depth\u2013width ratios and then inferred depths from satellite imagery-derived iceberg widths. We tested and applied the methods in two fjord systems in western Greenland with partially constrained bathymetry, Ilulissat Isfjord and Naajarsuit Fjord, to demonstrate their utility for inferring bathymetry using remote sensing datasets. Our results show that while the uncertainties associated with the methods are high (up to \u00b193 m), they provide critical first-order constraints on fjord bathymetry.<\/jats:p>","DOI":"10.3390\/rs11080935","type":"journal-article","created":{"date-parts":[[2019,4,18]],"date-time":"2019-04-18T11:58:21Z","timestamp":1555588701000},"page":"935","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["First-Order Estimates of Coastal Bathymetry in Ilulissat and Naajarsuit Fjords, Greenland, from Remotely Sensed Iceberg Observations"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3421-4459","authenticated-orcid":false,"given":"Jessica","family":"Scheick","sequence":"first","affiliation":[{"name":"School of Earth and Climate Sciences, University of Maine, Orono, ME 04469, USA"},{"name":"Climate Change Institute, University of Maine, Orono, ME 04469, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8266-7719","authenticated-orcid":false,"given":"Ellyn","family":"Enderlin","sequence":"additional","affiliation":[{"name":"School of Earth and Climate Sciences, University of Maine, Orono, ME 04469, USA"},{"name":"Climate Change Institute, University of Maine, Orono, ME 04469, USA"},{"name":"Department of Geosciences, Boise State University, Boise, ID 83725, USA"}]},{"given":"Emily","family":"Miller","sequence":"additional","affiliation":[{"name":"Climate Change Institute, University of Maine, Orono, ME 04469, USA"},{"name":"School of Marine Sciences, University of Maine, Orono, ME 04469, USA"}]},{"given":"Gordon","family":"Hamilton","sequence":"additional","affiliation":[{"name":"Formerly at School of Earth and Climate Sciences, University of Maine, Orono, ME 04469, USA"},{"name":"Formerly at Climate Change Institute, University of Maine, Orono, ME 04469, USA"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"257","DOI":"10.3189\/2012AoG60A136","article-title":"Spreading of warm ocean waters around Greenland as a possible cause for glacier acceleration","volume":"53","author":"Rignot","year":"2012","journal-title":"Ann.
