Observations on the composition of bottom muds in relation to the phosphate cycle in the inshore waters of the Malabar Coast

  • Published:
Proceedings / Indian Academy of Sciences

V. Summary

Data have been collected on the temperature, pH, silt colloidal matter, moisture and phosphate content of mud samples from two selected stations of the West Hill Sea along the Malabar Coast.

The variations in the several factors have revealed a distinct seasonal trend, the values being, in general, low for all the factors during the monsoon months.

The bottom muds contain large quantities of interstitial and adsorbed phosphates in the non-monsoon period. During the monsoon there is a rapid release of phosphates into the overlying column of water.

The factors associated with the monsoon release of phosphates from the muds are examined.
