The Southern Ocean greatly contributes to the regulation of global climate by controlling important heat and carbon exchanges between atmosphere ocean. Rates change on decadal timescales are therefore impacted oceanic processes taking place in Ocean, yet too little is known about these processes. Limitations come both from lack observations this extreme environment its inherent sensitivity intermittent at scales that not well captured current Earth system models. Carbon Heat Impact Climate...
In winter 2015, Antarctic sea ice underwent a drastic change, transitioning from period of record high coverage to low coverage. While both an intensified atmospheric circulation and warmer ocean temperatures have been invoked as possible causes for this regime shift, detailed process understanding is still missing. Using ~110,000 hydrographic profiles the seasonal zone Southern Ocean reanalysis, we reconcile how storm-driven mixing interacted with subsurface warming change state. We observe...
<title>Abstract</title> Between 2015 and 2017, Antarctic sea ice underwent a drastic change, transitioning from period of record high area to low area. While both an intensified atmospheric circulation warmer ocean temperatures in 2016 have been invoked as possible causes for this regime shift, detailed process understanding is still missing. Using ~110,000 hydrographic profiles the seasonally ice-covered Southern Ocean reanalysis, we show that change state was preconditioned by gradual...
Abstract The Southern Ocean (SO) is central to the global overturning circulation. South of Antarctic Polar Front, Winter Water (WW) forms in wintertime mixed layer (ML) and becomes a subsurface following summertime restratification ML, overlaying upwelled deep waters. Model simulations show that WW acts as conduit seasonally transform waters into intermediate Yet, there remains little observational evidence distribution seasonal characteristics WW. Using 18 years situ observations, we...
<title>Abstract</title> Ice sheet mass loss is one of the clearest manifestations climate change, with Antarctica discharging into ocean via melting glacial ice or through calving. This calving produces icebergs which can modify water properties, often at great distances from source. affects upper physics and primary productivity, implications for atmospheric carbon drawdown. Detailed understanding iceberg modification waters has hitherto been hindered by a lack proximal measurements. Here,...
The Southern Ocean is central to the global overturning circulation. South of Antarctic Polar Front, Winter Water (WW) forms in wintertime mixed layer below sea ice and becomes a subsurface following summertime restratification layer, overlaying upwelled deep waters. Model simulations show that WW acts as conduit seasonally transform waters into intermediate Yet, there remains little observational evidence distribution seasonal characteristics WW. Using 18 years situ observations , we...
