{"doi":"10.2478/v10183-012-0010-7","title":"Surface and bed morphology of Hansbreen, a tidewater glacier in Spitsbergen","abstract":"<jats:title>Surface and bed morphology of Hansbreen, a tidewater glacier in Spitsbergen</jats:title><jats:p>Hansbreen, a medium size tidewater glacier in Southern Spitsbergen (Svalbard) is one of the most intensively studied glaciers in the Arctic. This work presents new digital elevation models of its surface and basal topography based on data collected during GPS/GPR campaigns conducted in the spring seasons of 2005 and 2008, as well as on other recent topographic/bathymetric sources. The mean thickness of the glacier is calculated as 171 m and its volume is estimated to be 9.6 (±0.1) km<jats:sup>3</jats:sup>. The main feature of the bedrock morphology is a vast depression that is overdeepened below sea level and extends as far as 11 km upstream from the glacier front. This depression is divided into four individual basins by distinct sills that are related to the main geological/tectonic features of the area. The bedrock morphology affects considerably the glacier's surface topography. The influence of bedrock and surface relief on the subglacial drainage system geometry is discussed. Vast depressions on the glacier surface favor concentration of meltwater and development of moulin systems.</jats:p>","journal":"Polish Polar Research","year":2012,"id":33822,"datarank":2.03172115536315,"base_score":4.1588830833596715,"endowment":4.1588830833596715,"self_citation_contribution":0.6238324625039509,"citation_network_contribution":1.4078886928591992,"self_endowment_contribution":0.6238324625039509,"citer_contribution":1.4078886928591992,"corpus_percentile":null,"corpus_rank":null,"citation_count":63,"citer_count":41,"citers_with_citation_signal":36,"citers_with_endowment":36,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":176205,"name":"Jacek Jania","orcid":null,"position":1,"is_corresponding":false},{"id":176206,"name":"Dariusz Puczko","orcid":null,"position":2,"is_corresponding":false},{"id":176207,"name":"Leszek Kolondra","orcid":null,"position":3,"is_corresponding":false},{"id":176208,"name":"Tomasz Budzik","orcid":null,"position":4,"is_corresponding":false},{"id":176204,"name":"Mariusz Grabiec","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":4.1588830833596715,"endowment":4.1588830833596715,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24523987","pmcid":null,"openalex_id":"https://openalex.org/W2093246803","authors":[],"funders":[{"funder_name":"European Commission","grant_id":"226375","title":"Ice2sea - estimating the future contribution of continental ice to sea-level rise"}],"total_grants":1,"fwci":1.6283,"citation_percentile":0.83611663,"influential_citations":5,"citation_trend":[{"year":2013,"count":2},{"year":2014,"count":1},{"year":2015,"count":4},{"year":2016,"count":7},{"year":2017,"count":8},{"year":2018,"count":4},{"year":2019,"count":8},{"year":2020,"count":8},{"year":2021,"count":3},{"year":2022,"count":5},{"year":2023,"count":7},{"year":2024,"count":4},{"year":2025,"count":2}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://doi.org/10.2478/v10183-012-0010-7","host_type":"journal"},{"url":"https://doi.org/10.2478/v10183-012-0010-7","host_type":"GREEN"},{"url":"https://doi.org/10.2478/v10183-012-0010-7","host_type":"publisher"},{"url":"http://content.sciendo.com/view/journals/popore/33/2/article-p111.xml","host_type":"publisher"},{"url":"https://www.degruyter.com/view/j/popore.2012.33.issue-2/v10183-012-0010-7/v10183-012-0010-7.pdf","host_type":"publisher"},{"url":"http://hdl.handle.net/20.500.12128/620","host_type":"repository"},{"url":"http://dx.doi.org/10.2478/v10183-012-0010-7","host_type":""},{"url":"https://dx.doi.org/10.2478/v10183-012-0010-7","host_type":""},{"url":"https://doi.org/https://doi.org/10.2478/v10183-012-0010-7","host_type":""},{"url":"https://doi.org/https://doi.org/20.500.12128/620","host_type":""}],"fields_of_study":["Cryospheric studies and observations","Climate change and permafrost","Landslides and related hazards","Geology","Environmental Science","Geography","0103 physical sciences","01 natural sciences","0105 earth and related environmental sciences"],"mesh_terms":[],"keywords":["Geology","Tidewater glacier cycle","Glacier","Bedrock","Tidewater","Geomorphology","Glacier mass balance","Glacier morphology","Bathymetry","Glacier ice accumulation","Arctic","Rock glacier","Meltwater","Physical geography","Oceanography","Ice calving","Antarctic sea ice","Geography","Arctic ice pack","Svalbard","550","Bedrock Topography","Glaciology"],"sdg_mappings":[{"sdg_number":13,"sdg_label":"13.
