THE OCEANS, THEIR STRUCTURES AND FEATURES

Also, it causes sediments to be carried, the particles 

 sometimes coloring the water and allowing one to see 

 the feeder and neck channels dissipate into the head. 

 However, the most important effect of rip tides is 

 the danger they create to swimmers. Probably no 

 human can swim against the fully developed rip of a 

 neck channel. On the other hand, even a fair swim- 

 mer need not drown if caught in a neck channel. To 

 escape, the correct procedure is to ride the current 

 until one is beyond its influence. From such a place, 

 one can swim to the shore through an area not af- 

 fected by a rip current.
