Links between CO 2, glaciation and water flow: reconciling the Cenozoic history of the Antarctic Circumpolar Current
... Since Kennett’s hypothesis of an ACC control on the ma- jor Antarctic glaciation at the EO transition, the timing of its initiation has been a matter of debate. Due to the com- plex tectonic evolution of the Drake and ...

Southern Ocean overturning across streamlines in an eddying simulation of the Antarctic Circumpolar Current
... Abstract. An eddying global model is used to study the char- acteristics of the Antarctic Circumpolar Current (ACC) in a streamline-following framework. Previous model-based es- timates of the meridional ...

Variation of Antarctic circumpolar current and its intensification in relation to the southern annular mode detected in the time variable gravity signals by GRACE satellite
... The southern annular mode (SAM) in the atmosphere and the Antarctic circumpolar current (ACC) in the ocean play decisive roles in the climatic system of the mid‑ to high‑latitude southern hemisphere. Using ...

Ekman currents in the Antarctic circumpolar current
... Classical Ekman theory assumes the momentum mixing within the upper ocean is set by a constant eddy viscosity. However, previous observational studies have found Ekman spirals to be compressed, with different viscosities ...

Antarctic notothenioid fish: what are the future consequences of ‘losses’ and ‘gains’ acquired during long term evolution at cold and stable temperatures?
... The origins of the modern Antarctic fish fauna are poorly understood as a result of a minimal fossil record (Eastman, 1993). It is generally thought that today ’ s fauna originated from a sluggish, benthic stock that ...
