ON THE NUTRIENT SALTS OF THE SOUTHERN OCEAN IN THE SECTION BETWEEN QUEEN MAUD LAND AND SOUTH AFRICA (Reports read at the Symposium on Polar Oceanography)
The serial observations were carried out along 10°-15° E at every 5° in latitude in JARE-7. In the Antarctic Circumpolar Water, 24 μg-atoms/L of phosphate-P, 100 μg-atoms/L of silicate-Si and 35-38 μg-atoms/L of nitratc-N were observed There was difference between the distribution of phosphate-P and...

| Summary: | The serial observations were carried out along 10°-15° E at every 5° in latitude in JARE-7. In the Antarctic Circumpolar Water, 24 μg-atoms/L of phosphate-P, 100 μg-atoms/L of silicate-Si and 35-38 μg-atoms/L of nitratc-N were observed There was difference between the distribution of phosphate-P and that of silicate-Si, the maximum values of phosphate-P and mtrate-N were observed in 400-600m layer at 60°S, but that of silicate-Si was at a depth of 1,500m Regeneration of phosphate-P and nitrate-N was observed in 400-600m layer in the Antarctic zone and the Antarctic Intermediate Water, and the regeneration of almost all silicate-Si was estimated in the Antarctic zone |
