Effect of Moon Phase on Physical Parameters at the Mouth of the River

Light from the sun is the need for living things both on land and in the air. The moon, as a medium that reflects sunlight in one month, has several phases. This phase affects the situation on earth, especially river mouths. This study aims to determine the effect of the moon phase on physical parameters (water temperature and air temperature) at the mouth of the river. This research was conducted in 4 moon phases on the physics parameters at three coastal estuaries during the day and night. Based on the study results, it was found that the moon phase of the physical parameters is very influential on the number of micro-organisms. The number of organisms in each estuary also shows different characteristics according to moon phase conditions. Keywords: moon phase, physical parameter
