{"cited_by_count":624795,"description":"This cluster of papers focuses on the variability and decline of Arctic sea ice, including topics such as climate change impacts, remote sensing techniques, ocean circulation, freshwater cycle, and comparisons with Antarctic sea ice. The research synthesizes historical trends, observational data, and modeling to understand the rapid changes in the Arctic sea ice cover.","display_name":"Arctic and Antarctic ice dynamics","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11459","wikipedia":"https://en.wikipedia.org/wiki/Arctic_sea_ice_decline"},"field_id":"19","id":"T11459","keywords":[{"display_name":"Arctic sea ice","id":"arctic-sea-ice","score":0.6707,"url":"https://openalex.org/keywords/arctic-sea-ice"},{"display_name":"sea ice","id":"sea-ice","score":0.3909,"url":"https://openalex.org/keywords/sea-ice"},{"display_name":"Arctic Ocean","id":"arctic-ocean","score":0.2203,"url":"https://openalex.org/keywords/arctic-ocean"},{"display_name":"sea ice thickness","id":"sea-ice-thickness","score":0.813,"url":"https://openalex.org/keywords/sea-ice-thickness"},{"display_name":"sea ice concentration","id":"sea-ice-concentration","score":0.6202,"url":"https://openalex.org/keywords/sea-ice-concentration"},{"display_name":"Antarctic sea ice","id":"antarctic-sea-ice","score":0.64,"url":"https://openalex.org/keywords/antarctic-sea-ice"},{"display_name":"MOSAiC expedition","id":"mosaic-expedition","score":0.5256,"url":"https://openalex.org/keywords/mosaic-expedition"},{"display_name":"sea ice decline","id":"sea-ice-loss","score":0.3012,"url":"https://openalex.org/keywords/sea-ice-loss"},{"display_name":"sea ice extent","id":"sea-ice-extent","score":0.5731,"url":"https://openalex.org/keywords/sea-ice-extent"},{"display_name":"first-year ice","id":"first-year-sea-ice","score":0.7708,"url":"https://openalex.org/keywords/first-year-sea-ice"},{"display_name":"sea ice drift","id":"sea-ice-drift","score":0.8801,"url":"https://openalex.org/keywords/sea-ice-drift"},{"display_name":"ice thickness","id":"ice-thickness","score":0.2288,"url":"https://openalex.org/keywords/ice-thickness"},{"display_name":"Beaufort Sea","id":"beaufort-sea","score":0.2559,"url":"https://openalex.org/keywords/beaufort-sea"},{"display_name":"Arctic climate","id":"arctic-climate","score":0.2563,"url":"https://openalex.org/keywords/arctic-climate"},{"display_name":"marginal ice zone","id":"marginal-ice-zone","score":0.5339,"url":"https://openalex.org/keywords/marginal-ice-zone"},{"display_name":"multi-year ice","id":"multiyear-ice","score":0.7236,"url":"https://openalex.org/keywords/multiyear-ice"},{"display_name":"Fram Strait","id":"fram-strait","score":0.3575,"url":"https://openalex.org/keywords/fram-strait"},{"display_name":"sea ice dynamics","id":"sea-ice-dynamics","score":0.7335,"url":"https://openalex.org/keywords/sea-ice-dynamics"},{"display_name":"fast ice","id":"landfast-sea-ice","score":0.5562,"url":"https://openalex.org/keywords/landfast-sea-ice"},{"display_name":"laser altimetry","id":"laser-altimetry","score":0.4456,"url":"https://openalex.org/keywords/laser-altimetry"},{"display_name":"surface elevation","id":"surface-elevation","score":0.3834,"url":"https://openalex.org/keywords/surface-elevation"},{"display_name":"ridge detection","id":"ridge-detection","score":0.6146,"url":"https://openalex.org/keywords/ridge-detection"},{"display_name":"pressure ridge sails","id":"pressure-ridge-sails","score":0.9919,"url":"https://openalex.org/keywords/pressure-ridge-sails"},{"display_name":"Arctic sea ice decline","id":"arctic-sea-ice-loss","score":0.3958,"url":"https://openalex.org/keywords/arctic-sea-ice-loss"},{"display_name":"drifting sea ice","id":"drift-ice","score":0.6581,"url":"https://openalex.org/keywords/drift-ice"}],"legacy_keywords":["Arctic","Sea Ice","Decline","Variability","Climate Change","Remote Sensing","Ocean Circulation","Freshwater Cycle","Antarctic Comparison","Atmospheric Circulation"],"openalex_id":"https://openalex.org/T11459","source_created_date":"2024-01-23T15:27:10","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1902","url":"/topics/T11459","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11459","works_count":58172,"label":"Arctic and Antarctic ice dynamics","provider":"openalex","revision":"1891da85f036b0c2","taxonomy_revision":"f050b5d4780b1289","title":"Arctic and Antarctic ice dynamics","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36183023057782011","address_version":"morton4x16-v1","coordinates":[3,19,1902,11459],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
