Short summary
Sea-ice leads facilitate the exchange of heat and moisture between the ocean and the atmosphere during wintertime. We present a new dataset on monthly wintertime sea-ice leads in the Southern Ocean from 2003 to 2023. Our study reveals distinct regional patterns, seasonal variability, and small but significant trends. Here, we present initial findings on Southern Ocean lead dynamics to support future research into the complex pan-Antarctic interactions among sea ice, ocean, and atmosphere.
