a,b, Time series (mean ± s.d.) of pressure ridge densities (DR (n km−1)) for sails higher than 0.6 m in the two regions (TPD (a), Lincoln Sea (b)) across different campaigns. The size of the symbols indicates the survey distance covered per campaign. Trends (black lines) with 95% CIs (grey shading) are illustrated in the background. c,d, Development (mean ± s.d.) of ridge spacing (SR (m)) for TPD (c) and Lincoln Sea (d). e,f, Height (HS (m)) of sails larger than 0.6 m for TPD (e) and Lincoln Sea (f). g,h, Calculated 10 m neutral atmospheric drag coefficient (Cdn10) for H0 = 0.4 m for TPD (g) and Lincoln Sea (h). Statistical metrics (see Methods for details) are provided in Supplementary Table 3.
