Sea Ice Prediction Network-South: coordinating seasonal predictions of sea ice for the Southern Ocean [in 'State of the Climate in 2019']

The Sea Ice Prediction Network (SIPN) is a community-wide\r\neffort to assess seasonal sea ice forecasts for the Arctic. It has\r\nbeen in operation since 2008, when it started life as the SEARCH\r\nSea Ice Outlook (Hamilton and Stroeve 2016). This international\r\ninitiative has created a strong community of researchers from\r\nvarious backgrounds with a common interest in forecasting sea\r\nice conditions in the Arctic Ocean.
