Freshening drives contraction of Antarctic Bottom Water in the Australian Antarctic Basin [PDF]
Geophysical Research Letters, 2014 AbstractAntarctic Bottom Water (AABW) in the Australian Antarctic Basin has become fresher and lighter since the late 1960s, with largest changes observed near the sources of AABW. The volume of AABW with neutral density (γn) > 28.30 kg m−3 decreased by ≥50% between 1969–1971 and 2008–2012, thinning at a rate of >100 m per decade.

SPREADING OF ANTARCTIC BOTTOM WATER IN THE ATLANTIC OCEAN
Geography, Environment, Sustainability, 2012 This paper describes the transport of bottom water from its source region in the Weddell Sea through the abyssal channels of the Atlantic Ocean. The research brings together the recent observations and historical data.

Southern Ocean evidence for recurring West Antarctic Ice Sheet destabilization during Marine Isotope Stage 11 [PDF]
Nature CommunicationsMillennial-scale deoxygenation of Antarctic Bottom Water (AABW) in the Atlantic Southern Ocean during past interglacials was linked to West Antarctic Ice Sheet (WAIS) melt-driven suppression of dense water formation along the Antarctic margin.

Antarctic Bottom Water Sensitivity to Spatio‐Temporal Variations in Antarctic Meltwater Fluxes
Geophysical Research Letters, 2023 Ice sheet melting into the Southern Ocean can change the formation and properties of the Antarctic Bottom Water (AABW). Ocean models often mimic ice sheet melting by adding freshwater fluxes in the Southern Ocean under diverse spatial distributions.

Boundary Upwelling of Antarctic Bottom Water by Topographic Turbulence
AGU Advances, 2023 The lower cell of the meridional overturning circulation (MOC) is sourced by dense Antarctic Bottom Waters (AABWs), which form and sink around Antarctica and subsequently fill the abyssal ocean.

Circulation, mixing, and production of Antarctic Bottom Water
Progress in Oceanography, 1999 The Antarctic source of bottom water to the abyssal layer of the World Ocean is examined, as well as its large-scale flow pattern and ultimate entrainment rate into the deep water above.

Antarctic Bottom Water production from the Vincennes Bay Polynya, East Antarctica
Geophysical Research Letters, 2014 One year moorings at depths greater than 3000 m on the continental slope off Vincennes Bay, East Antarctica, reveal the cold (

On the Consumption of Antarctic Bottom Water in the Abyssal Ocean [PDF]
Journal of Physical Oceanography, 2016 AbstractThe abyssal ocean is primarily filled by cold, dense waters formed around Antarctica and collectively referred to as Antarctic Bottom Water (AABW). At steady state, AABW must be consumed in the ocean interior at the same rate it is produced, but how and where this consumption is achieved remains poorly understood.

Impact of West Antarctic ice shelf melting on Southern Ocean hydrography [PDF]
The Cryosphere, 2020 Previous studies show accelerations of West Antarctic glaciers, implying that basal melt rates of these glaciers were previously small and increased in the middle of the 20th century. This enhanced melting is a likely source of the observed Ross Sea (RS)
