Description Study on the distrlbudon and correlation of inorganic phosphorus and dissolved oxygen and nitrites
and inorganic phosphorus at Karwar during 1965-1972 is made. The oxygen and phosphorus are inversely
related at depths. The Bay waters showed high oxygen content at surfee and low content at depths and
sea beds. But the waters outside the bay showed high dissolved oxygen content in the depiis than at the
surface. Here the subsurface waters showed supersaturations as against prac.icilly none in the bay
waters. The correlation coeflBcient (r) obtained for dissolved oxygen and inorganic phosphorus during
this investigation was 0.53 and found to be significant at 5 and 1 per cent level.
As regards the distribution of nitrites and inorganic phosphorus, there is a close parallelism between
nitrites and inorganic phosphorus and which is characterised by the presence of low concentration at
surface and the increasing concentration at depths- The correlation coefficient (r) was found to be not
significant at 5 and 1 per cent levels, the (r) value being 0.09. Similarly, the relationship between dissolved
oxygen and nitrite when studied, the correlation coefficient of 0.26 proved to be significant at 5 and 1 per
cent levels.
These nutrients bear a definite linearity at all levels. As the inorganic phosphorus and dissolved
oxygen show inverse relation, and as the inorganic phosphorus and nitrite bear linearity, it is obvious
that the relation between dissolved oxygen must also be inverse at depths. As the plant life much depends
on the concentrations ofthcse nutrients, it is of much value to study the distribution, interrelations and
fluctuations of nutrients in the sea.
