Wave spectral directions (cos(θ_r), in a–c) and spread (σ_θ, in d–f) are shown from July 30th (a and d), October 2nd (b and e), and the unaccompanied buoy when it entered ice (±4 h of the open water/ice transition) on August 31st (c and f). Scattering appears at high frequencies when the buoys drifted into partial ice cover. Directional spread increased for these frequencies on October 2nd, and somewhat on July 30th. For visual clarity, the median relative directions and spreads are shown for each ice fraction bin, rather than each profile (as in Figure 4).
