The (SIO) is a community network activity led by the Sea Ice Prediction Network-Phase 2 (SIPN2) Project Team with contributions from key partners. SIPN2 is a community of scientists and stakeholders to advance our understanding of the state and evolution of Arctic sea ice cover.

The September 2023 average Arctic sea-ice extent was 4.37 million square kilometres, the fifth lowest in the satellite record. This report provides a discussion and analysis of factors driving sea-ice extent during the 2023 melt season with a focus on the performance of contributed Outlooks compared to the observed September monthly mean sea-ice extent. The 2023 SIO effort has been supported with funds from NSF award #1331083.
