They are often seen as sites of intense ocean\u2013atmosphere heat exchange and as ice production factories. Given their importance, it is crucial to quantify the accuracy of satellite-derived polynya information. Polynyas in their early evolution phase are generally narrow and occur at scales likely too fine to be detected by widely used passive microwave (PMW) radiometric sensors. We derived 40 m scale polynya information over the western Ross Sea from high-resolution Synthetic Aperture Radar (SAR) Sentinel-1 C-band data and examined discrepancies with larger-scale estimates. We utilized two automated algorithms, supervised (a rule-based approach) and unsupervised (a combination of texture analysis with k-means clustering), to accurately identify the polynya areas. We generated data for validation using Sentinel-1 data at instances where polynyas can be visually delineated. Results from PMW sensors (NSIDC and AMSR2) and SAR-based algorithms (rule-based and texture-based) are compared with manually delineated polynya areas obtained through Sentinel-1. Analysis using PMW sensors revealed that NSIDC overestimates larger polynyas and underestimates smaller polynyas compared to AMSR2. We were more accurately able to identify polynya presence and area using Sentinel-1 SAR observations, especially in clear cases and cases when PMW data miscalculates the polynya\u2019s presence. Of our SAR-based algorithms, the rule-based approach was more accurate than the texture-based approach at identifying clear polynyas when validated against manually delineated regions. Altogether, we emphasize the need for finer spatio-temporal resolution data for polynya studies.<\/jats:p>","DOI":"10.3390\/rs15102545","type":"journal-article","created":{"date-parts":[[2023,5,12]],"date-time":"2023-05-12T09:26:13Z","timestamp":1683883573000},"page":"2545","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Delineating Polynya Area Using Active and Passive Microwave Sensors for the Western Ross Sea Sector of Antarctica"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-8502-1209","authenticated-orcid":false,"given":"Girija Kalyani","family":"Burada","sequence":"first","affiliation":[{"name":"School of Geography Environment and Earth Sciences, Victoria University of Wellington, Wellington 6012, New Zealand"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1456-6254","authenticated-orcid":false,"given":"Adrian","family":"McDonald","sequence":"additional","affiliation":[{"name":"School of Physical and Chemical Sciences, University of Canterbury, Christchurch 8041, New Zealand"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9141-2486","authenticated-orcid":false,"given":"James","family":"Renwick","sequence":"additional","affiliation":[{"name":"School of Geography Environment and Earth Sciences, Victoria University of Wellington, Wellington 6012, New Zealand"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8984-3201","authenticated-orcid":false,"given":"Ben","family":"Jolly","sequence":"additional","affiliation":[{"name":"Landcare Research, Palmerston North 4474, New Zealand"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,12]]},"reference":[{"key":"ref_1","first-page":"116","article-title":"Polynya Dynamics: A Review of Observations and Modeling: Polynya dynamics-observations and modeling","volume":"42","author":"Willmott","year":"2004","journal-title":"Rev.
