Jimbaran beach is one of the dirtiest beaches I have ever encountered.I stayed at the Intercontinental Jimbaran beach for two weeks three years ago.The water is certainly not clear.When the tide goes out the beach is densely littered with used toothpaste tubes and a multitude of other plastics.I went swimming and felt all sorts of debris brushing against my legs.I asked one of the hotel managers if he would swim in the beach in front of the hotel and his honest answer was “NEVER”!
I do not trust any of the research you have produced here.
