It prevents the comprehensive understanding of both the onshore and offshore geology as well as the relationship between the inner part of East Antarctica (EA) and the coastal sector of Victoria Land (VL). With the aim to reduce this gap, in this paper multiple geophysical dataset collected since the 1980s in Antarctica by Programma Nazionale di Ricerche in Antartide (PNRA) were integrated with geodetic observations. In particular, the analyzed data includes: (i) Geodetic time series from Trans Antarctic Mountains DEFormation (TAMDEF), and Victoria Land Network for DEFormation control (VLNDEF) GNSS stations installed in Victoria Land; (ii) the integration of on-shore (ground points data and airborne) gravity measurements in Victoria Land and marine gravity surveys performed in the Ross Sea and the narrow strip of Southern Ocean facing the coasts of northern Victoria Land. Gravity data modelling has improved the knowledge of the Moho depth of VL and surrounding the offshore areas. By the integration of geodetic and gravitational (or gravity) potential results it was possible to better constrain\/identify four geodynamic blocks characterized by homogeneous geophysical signature: the Southern Ocean to the N, the Ross Sea to the E, the Wilkes Basin to the W, and VL in between. The last block is characterized by a small but significant clockwise rotation relative to East Antarctica. The presence of a N-S to NNW-SSE 1-km step in the Moho in correspondence of the Rennick Geodynamic Belt confirms the existence of this crustal scale discontinuity, possibly representing the tectonic boundary between East Antarctica and the northern part of VL block, as previously proposed by some geological studies.<\/jats:p>","DOI":"10.3390\/rs13010087","type":"journal-article","created":{"date-parts":[[2020,12,29]],"date-time":"2020-12-29T10:04:46Z","timestamp":1609236286000},"page":"87","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Victoria Land, Antarctica: An Improved Geodynamic Interpretation Based on the Strain Rate Field of the Current Crustal Motion and Moho Depth Model"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4872-5222","authenticated-orcid":false,"given":"Antonio","family":"Zanutta","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria Civile, Chimica, Ambientale e dei Materiali (DICAM), Universit\u00e0 di Bologna, 40136 Bologna, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0064-5533","authenticated-orcid":false,"given":"Monia","family":"Negusini","sequence":"additional","affiliation":[{"name":"Istituto di Radioastronomia (IRA), Istituto Nazionale di Astrofisica (INAF), 40129 Bologna, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9815-1004","authenticated-orcid":false,"given":"Luca","family":"Vittuari","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Civile, Chimica, Ambientale e dei Materiali (DICAM), Universit\u00e0 di Bologna, 40136 Bologna, Italy"}]},{"given":"Leonardo","family":"Martelli","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Geofisica e Vulcanologia (INGV), Sezione di Bologna, 40128 Bologna, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9396-4519","authenticated-orcid":false,"given":"Paola","family":"Cianfarra","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze della Terra dell\u2019Ambiente e della Vita (DISTAV), Universit\u00e0 degli Studi di Genova, 16132 Genoa, Italy"}]},{"given":"Francesco","family":"Salvini","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze Geologiche, Universit\u00e0 degli Studi Roma Tre, 00146 Roma, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8553-345X","authenticated-orcid":false,"given":"Francesco","family":"Mancini","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Enzo Ferrari, Universit\u00e0 degli Studi di Modena e Reggio Emilia, 41125 Modena, Italy"}]},{"given":"Paolo","family":"Sterzai","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS), \u201cInfrastructures\u201d Section (IRI), 34010 Sgonico, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7084-5912","authenticated-orcid":false,"given":"Nicola","family":"Creati","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS), \u201cInfrastructures\u201d Section (IRI), 34010 Sgonico, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6158-2727","authenticated-orcid":false,"given":"Marco","family":"Dubbini","sequence":"additional","affiliation":[{"name":"Dipartimento di Storia Culture Civilt\u00e0 (DSCI), Universit\u00e0 di Bologna, 40124 Bologna, Italy"}]},{"given":"Alessandro","family":"Capra","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Enzo Ferrari, Universit\u00e0 degli Studi di Modena e Reggio Emilia, 41125 Modena, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1016\/j.jog.2004.10.002","article-title":"Terra Nova Bay GPS permanent station (Antarctica): Data quality and first attempt in the evaluation of regional displacement","volume":"39","author":"Negusini","year":"2005","journal-title":"J.
