... composite depth, the succession comprises drift sediments deposited from north-flowing intermediate Subantarctic Mode Water (SAMW, ∼250–800 m depth) and Antarctic Intermediate Water (∼800–1100 m depth). A change from the deposition of large, low-energy drifts on the middle slope to smaller, higher-energy...

The upwelled waters may have been an analog to Subantarctic Mode Waters, carrying nutrients into the eastern Atlantic and western Indian Oceans as the result of the initiation of a deep-reaching Antarctic Circumpolar Current, active Agulhas Leakage...

Instead, the additional presence of an increased nutrient pool provided by Subantarctic Mode Water played the decisive role in initiating and sustaining diatom production...

This water-mass shift allowed several species associated with SAIW (e.g., Bulimina alazanensis and Osangularia culter ) to reenter the Gulf after the last glacial interval. The position of several water-mass...

Although the latter 2 parameters show a strong negative correlation in the study area, we argue that the organic flux is the main controlling ecological factor. On the basis of an R-mode multivariate statistical analysis, 6 species...
