Long-term stability of the North Water Polynya and emerging productivity hotspots driven by sea-ice arch dynamics in Nares Strait
Nares Strait, at the southern edge of the Last Ice Area, is a key ecological gateway where seasonal sea-ice arches modulate ice export, stratification and light availability, shaping the timing and intensity of phytoplankton blooms. Using two decades (2003–2023) of satellite sea-ice observations combined with depth...
