Extended Data Fig. 9: Sea ice concentration budget.
From: Recent recovery of Antarctic Bottom Water formation in the Ross Sea driven by climate anomalies
a (b) Winter climatology of the divergence (residual) term of the sea ice concentration budget (see Methods). Values indicate sea ice concentration change over the winter season associated with divergence/residual term. Positive values indicate a source of sea ice (that is more divergence is negative, while more sea ice formation is positive). c (d) Anomalies of the divergence (residual) term temporally averaged between 2015 and 2018. Climatologies are calculated using all available years (that is 2003-2010 and 2013-2018). Here anomalies are the deviations from the climatologies. Overlaid in a (c) are vectors representing the winter climatology (2015-2018 anomaly) of sea ice drift (‘Kimura’23).
