Hydrography and nutrient dynamics along the 67 oE line of western Indian Ocean
Hydrography and nutrient dynamics of the meridional sections along the 67 o E line in the western Indian Ocean were investigated during the neutral IOD events of 2017-2019 periods. Vertical distribution of temperature, salinity, and dissolved oxygen along the meridional section showed the presence o...

Hydrography and nutrient dynamics of the meridional sections along the 67 o E line in the western Indian Ocean were investigated during the neutral IOD events of 2017-2019 periods.

The relative abundance of silicate over nitrate+nitrite (Si*) showed negative values at the depth of 750 m (27 o S), an indication of the northward intrusion of SAMW, and were observed in the shallow depth toward the north(~10 o S).
