Description
Litter observations data during the years 2023 and 2024 at Belgian beaches (total count, total weight, categorisation). Data of the SeaWatch-B project, the beach observation network where citizens monitor the state of the Belgian North Sea from the beach. This citizen science project is supported by the Flanders Marine Institute (VLIZ) and LifeWatch Belgium. moreData were repeatedly collected at the same stations (defined beaches). Approximately four times a year. Parameter 9 of SW-B: Litter on the high-water mark - Method: Collect over a length of 100m in the strand line all artificial waste of at least 2.5cm in size: plastic, rubber, textiles, paper, metal, glass, etc. Count the number of items and measure total weight with the crane scale (grams). Record both figures. Take one or more pictures of all the waste, with the ruler next to it. Parameter 15 of SW-B: Litter on the high-water mark: J-List - Method: Collect over a length of 100m in the strand line all artificial waste of at least 2.5cm in size: plastic, rubber, textiles, paper, metal, glass, etc. (idem parameter 9) – also man-made and/or processed stones and wood. Score all items in categories according to the J-List* and count them.

We would like to thank all of them for their valuable contributions.
