Short summary
Global bottom water originates from high-salinity shelf water (HSSW), formed by intense sea ice production (SIP) in the Southern Ocean. This study uses numerical outputs for the Ross Sea to examine the extreme HSSW event in 2007, when atmospheric circulations enhanced SIP, resulting in the highest HSSW volume in a decade. However, salinity was low, owing to increased meltwater. The findings highlight the complex interplay between SIP and ice shelf melting, with key implications for ocean processes.
