On suspended barite and the oxygen minimum in the Southern Ocean
Provedor de dados: 27
Autores: Dehairs, F.A.; Goeyens, L.; Stroobants, N.; Bernard, P.; Goyet, C.; Poisson, A.; Chesselet, R.
Particulate Ba profiles were measured in the Indian sector of the southern ocean. The largest fraction (&gt;80%) of this barium is present as barite microcrystals. The profiles of total barium are characterized by a subsurface maximum between 200 and 500 m depth in the vicinity of the oxygen minimum. Highest barium values are found just south of the Polar Front, while lowest values occur close to the Antarctic Divergence. Between the divergence and the Polar front a tight inverse relationship is observed between oxygen in the oxygen minimum and barium in the barium maximum. This relationship disappears north of the Polar Front. Since suspended barite is known to be of biological origin, the correlation of barite with oxygen suggests that the observed...

Barite formation in the Southern Ocean water column
Provedor de dados: 27
Autores: Stroobants, N.; Dehairs, F.A.; Goeyens, L.; Vanderheijden, N.; Van Grieken, R.
The intensity of past biological activity can be correlated with the occurrence of suspended and sedimented barite (BaSO&lt;sub&gt;4&lt;/sub&gt;). To date, there is a lack of information on the processes controlling the production of pelagic barite. During the EPOS-2 cruise (November-December 1988), situated in the Scotia Sea-Weddell Sea Confluence, suspended water samples were taken for analysis of total Ba by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and for scanning electron microscopy-electron microprobe (SEM-EMP).The vertical profiles of particulate barium generally show a Ba maximum between 200 and 500 m. SEM-EMP investigation on Scotia-Weddell Sea Confluence profiles provide a possible explanation for the origin of this...
