Observing Antarctic Bottom Water in the Southern Ocean [PDF]
Frontiers in Marine Science, 2023 Dense, cold waters formed on Antarctic continental shelves descend along the Antarctic continental margin, where they mix with other Southern Ocean waters to form Antarctic Bottom Water (AABW).

No detectable Weddell Sea Antarctic Bottom Water export during the Last and Penultimate Glacial Maximum [PDF]
Nature Communications, 2020 The Southern Ocean plays a key role in glacial-interglacial transitions and today, Weddell Sea derived Antarctic Bottom Water is one of the most important deep water masses.

Reversal of freshening trend of Antarctic Bottom Water in the Australian-Antarctic Basin during 2010s. [PDF]
Sci Rep, 2020 The Antarctic continental margin supplies the densest bottom water to the global abyss. From the late twentieth century, an acceleration in the long-term freshening of Antarctic Bottom Waters (AABW) has been detected in the Australian-Antarctic Basin ...

The suppression of Antarctic bottom water formation by melting ice shelves in Prydz Bay [PDF]
Nature Communications, 2016 Antarctic bottom water (AABW) production is critical to the global ocean overturning circulation. Here, the authors show new observations of AABW formation from seal CTD data in Prydz Bay, East Antarctica that highlights its susceptibility to increased ...

Tides regulate the flow and density of Antarctic Bottom Water from the western Ross Sea. [PDF]
Sci Rep, 2023 Antarctic Bottom Water (AABW) stores heat and gases over decades to centuries after contact with the atmosphere during formation on the Antarctic shelf and subsequent flow into the global deep ocean.

Dominant frazil ice production in the Cape Darnley polynya leading to Antarctic Bottom Water formation. [PDF]
Sci Adv, 2022 Antarctic Bottom Water (AABW) occupies the abyssal layer of the world ocean and contributes to the global overturning circulation. It originates from dense shelf water, which forms from brine rejection during sea ice production.

Improving Antarctic Bottom Water precursors in NEMO for climate applications [PDF]
Geoscientific Model Development, 2023 The world's largest ice shelves are found in the Antarctic Weddell Sea and Ross Sea where complex interactions between the atmosphere, sea ice, ice shelves and ocean transform shelf waters into High Salinity Shelf Water (HSSW) and Ice Shelf Water (ISW ...

Circum-Antarctic bottom water formation mediated by tides and topographic waves. [PDF]
Nat CommunThe 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.

Freshening by glacial meltwater enhances melting of ice shelves and reduces formation of Antarctic Bottom Water. [PDF]
Sci Adv, 2018 Glacial meltwater stops bottom-water formation, allowing warm ocean waters to reach Antarctic ice shelves and drive rapid melting. Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool and salinify waters on the ...
