1.Research Preparation 1)Define the research topic. 2)Conduct literature review and gather relevant knowledge and theories. 3)Define the research objectives. 4)Determine the sampling points within the study area. 2. Processing floor 1) Conduct research operations planning. 2) Conduct a survey of the area to be researched. 3) Collect soil and water samples to measure soil and water temperature using a thermometer. Read the values and record the results. 4) Measure the salinity of water with a Salinity Meter, read the words and record the results. 5) Measure the acidity-alkalinity (pH) of the soil with a universal indicator, read the value and record the results. 6) Analyze the values obtained from the survey and summarize the study results.
The study of physical factors affecting the density of wedge clams on Samran Beach, Hat Samran District, Trang Province aimed to investigate the physical factors influencing the density of wedge clams in the area of Samran Beach, Hat Samran District, Trang Province. The study examined the density of wedge clams, water temperature, pH, dissolved oxygen, and salinity to understand the density of wedge clams in the Samran Beach area, Hat Samran District, Trang Province. The results showed that the density of wedge clams on Samran Beach, Hat Samran District, Trang Province was influenced by physical and chemical factors. The water temperature ranged from 29.4-33.3 °C, which is conducive to the survival of aquatic organisms. The pH ranged from 5.6-6.8, considered normal and suitable for aquatic life. The dissolved oxygen (DO) ranged from 4.29-7 mg/l, and the salinity ranged from 28.4-30.64 ppt. The cloud cover showed that Steatocumulus clouds were more prevalent than Cirrus clouds, indicating high humidity or changing weather conditions.
