1 Preliminary survey
　Prior to the main survey, conduct a preliminary study to understand how the beach and surrounding environment. Document the dates of past beach-cleaning activities.

2 Main survey

• Select a survey site that is a representative of the general beach. Set up 10 x 10 m survey grids between the shoreline and beach edge.
• As a general rule, set up 3 survey grids per row. If the beach width is too narrow the number of surveys grids could be reduced to two per row.
• When setting up the survey grids, first mark the 4 corners of the grid with stakes. Use a rope to connect the stakes in order to define the boundaries of the grids.
• Collect the marine litters found within the survey grid boundaries. Classify the collected marine litters into the following 8 litter categories (Plastic, Styrofoam, Cloth, Metal, Rubber, Paper, Glass/Ceramic and Other artificial objects). For each category, count the number and measure the weight of the collected litters. Where possible identify the litter's place origin (e.g. domestic or foreign) by checking any labels on the litter.
