Fig. 4: Biomarker-based sea-ice reconstructions for cores 11GC (JR142-11GC) and 06GC (HH15-06GC).
From: Seasonal sea ice persisted through the Holocene Thermal Maximum at 80°N
Spring sea-ice concentrations (SpSIC %) are shown for: a 11GC, and b 06GC in bold dark blue and dark green lines, respectively; error envelopes of RMSE (root mean square error) are denoted by lighter blue (11GC) and medium green (06GC). Sea-ice categories follow Köseoğlu et al.11.
