Beach litter surveys can be undertaken in either of two ways; a) surveyors form skirmish
lines parallel to the coast (> 5 persons) or b) surveyors form skirmish lines at right angles to the coast (2-5 persons). Inboth cases there should be around 2 m between persons forming the line with each person responsible for noting or collecting all litter in the area between themselves and the person on the adjacent line
