| Summary: | This deliverable is a new dataset of sea ice production (SIP) in Antarctic coastal polynyas, critical regions forsea ice formation and dense water formation. Using Earth Observation data and atmospheric reanalysis, weuse a heat budget method to estimate the SIP. We use sea ice concentration (SIC) from passive microwavesensors and ECMWF ERA5 reanalysis for near-surface wind speed and surface air temperature. Comparisonagainst previous literature shows broad consistency in spatial patterns and magnitude of ice production, withnotable variations across larger polynyas. Despite simplifications and thereby increased uncertainties in theabsolute ice production values, the data set provides valuable insights into the dynamics and variability ofAntarctic polynya SIP for the period 1992-2023. ... |
