The p wave of the electrocardiogram is a signal from
Ratling [72]

The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.

An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.

The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.

This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.

In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.
