The influence of sea ice on the shipborne gravity measurements was mainly concentrated in the 0\u20136 km wavelength range, and the standard deviation of the noise amplitudes was 2.62 mGal. Compared to ice-free regions, the accuracies in the region with floating ice were reduced by 13% for DTU21 and 6% for SV31. Due to the influence of sea ice, satellite altimetric gravity data lose significant information in the 9\u201312 km wavelength range. The coherence curve of the shipborne gravity with bathymetry was nearly the same as that of the satellite altimetric gravity. The satellite data contain nearly all of the significant information that is present in the shipborne data. The differences between the shipborne and satellite gravity data are small and can be used to study the crustal structure of the Arctic.<\/jats:p>","DOI":"10.3390\/rs14010041","type":"journal-article","created":{"date-parts":[[2021,12,23]],"date-time":"2021-12-23T21:40:21Z","timestamp":1640295621000},"page":"41","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparison of Marine Gravity Measurements from Shipborne and Satellite Altimetry in the Arctic Ocean"],"prefix":"10.3390","volume":"14","author":[{"given":"Zilong","family":"Ling","sequence":"first","affiliation":[{"name":"College of Geodesy and Geomatics, College of Earth Science and Engineering, Shandong University of Science and Technology, Qingdao 266590, China"},{"name":"Key Laboratory of Submarine Geosciences, Ministry of Nature Resources, Hangzhou 310012, China"},{"name":"Second Institute of Oceanography, Ministry of Nature Resources, Hangzhou 310012, China"},{"name":"Laboratory for Marine Mineral Resources, Pilot National Laboratory for Marine Science and Technology, Qingdao 266237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5325-8086","authenticated-orcid":false,"given":"Lihong","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Geodesy and Geomatics, College of Earth Science and Engineering, Shandong University of Science and Technology, Qingdao 266590, China"},{"name":"Laboratory for Marine Mineral Resources, Pilot National Laboratory for Marine Science and Technology, Qingdao 266237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1205-989X","authenticated-orcid":false,"given":"Tao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Submarine Geosciences, Ministry of Nature Resources, Hangzhou 310012, China"},{"name":"Second Institute of Oceanography, Ministry of Nature Resources, Hangzhou 310012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guojun","family":"Zhai","sequence":"additional","affiliation":[{"name":"Naval Institute of Hydrographic Surveying and Charting, Tianjin 300061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7934-5850","authenticated-orcid":false,"given":"Fanlin","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Geodesy and Geomatics, College of Earth Science and Engineering, Shandong University of Science and Technology, Qingdao 266590, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,23]]},"reference":[{"key":"ref_1","first-page":"883","article-title":"Isostatic compensation of tectonic features of the Mid-Atlantic Ridge: 25\u201327\u00b030\u2032 S","volume":"22","author":"Blackman","year":"1991","journal-title":"J.
