From: Emerging outflow of not-so-dense shelf water from an East Antarctic polynya
a Absolute Salinity–Conservative Temperature plot within the area of interest (a) before and (b) after 2011. Markers are coloured by data platform type, whereas the 2024 CCHDO data is indicated by the black edge colour. Gray scatters in the background are CCHDO data from the Mertz region. Locations of corresponding hydrographic stations are plotted in (c) and (d) for before and after 2011, respectively. MEOP data south of 65 °S is removed for ease of comparison with the similar spatial coverage.
