Algal colonization of young arctic sea ice in spring
The importance of newly formed sea ice in spring is likely to increase with formation of leads in a more dynamic Arctic icescape. We followed the ice algal species succession in young ice (≤ 0.27 m) in spring at high temporal resolution (sampling every second day for 1 month in May–June 2015) in the...

The importance of newly formed sea ice in spring is likely to increase with formation of leads in a more dynamic Arctic icescape.
