DOI: 10.1029/2020gl089467

Abstract: There are two varieties of Antarctic Bottom Water present in the Australian Antarctic Basin (AAB): locally produced Adélie Land Bottom Water (ALBW) and distantly produced Ross Sea Bottom Water (RSBW). Between 2014 and 2018, RSBW… read more here.

DOI: 10.1029/2023gl106342

Abstract: Antarctic Bottom Water (AABW) transports surface nutrients deep into the ocean, sequestering them for centuries. Enhancing its biological carbon fixation could augment carbon sinks and reduce atmospheric CO2. Yet, it is uncertain if AABW receives… read more here.

DOI: 10.1029/2025gl114809

Abstract: Paleo‐proxy data indicate that during the Last Glacial Maximum (LGM), the volume of Antarctic Bottom Water (AABW) in the Atlantic was nearly four times greater than it is today. We employed an ocean‐only model to… read more here.

DOI: 10.1038/s41467-024-46086-1

Abstract: The downslope plumes of dense shelf water (DSW) are critical for the formation of Antarctic Bottom Water (AABW), and thus to the exchange of heat and carbon between surface and abyssal ocean. Previous studies have… read more here.

DOI: 10.1038/s41467-025-62958-6

Abstract: The rapid CO2 rise during the early deglaciation is often linked to enhanced ventilation by intensified Antarctic Bottom Water (AABW) overturning. The recorded radiocarbon ventilation seesaw during the early deglaciation, which describes improved Southern Ocean… read more here.

DOI: 10.1134/s1028334x17050026

Abstract: We used a numerical model of the ocean circulation with a high spatial resolution to obtain estimates of the kinematic characteristics of Antarctic Bottom Water flow through the abyssal Vema Channel in the southwestern part… read more here.

DOI: 10.1146/annurev-marine-121916-063414

Abstract: Antarctic Bottom Water (AABW) is the coldest, densest, most prolific water mass in the global ocean. AABW forms at several distinct regions along the Antarctic coast and feeds into the bottom limb of the meridional… read more here.

DOI: 10.1175/jpo-d-17-0007.1

Abstract: AbstractZonal momentum input into the Antarctic Circumpolar Current (ACC) by westerly winds is ultimately removed via topographic form stress induced by large bathymetric features that obstruct the path of the current. These bathymetric features also… read more here.
