At the coastal survey

Source A: an original contemporary non-fiction-style account.

Our beach survey began at nine on Saturday, before the visitors arrived. The organiser gave each pair a clipboard and a reusable sack. We were asked to record what we found along a marked fifty-metre stretch of sand, rather than wander wherever we pleased. My partner, Jaya, wrote down the numbers while I collected ordinary litter. We had been told to leave sharp objects untouched and point them out to the organiser.

Bottle caps were the most common items in our section. Near the steps I also found a small green toy boat, which we placed beside the information hut in case its owner returned. By half past ten our sack was nearly full. The organiser weighed it before emptying it into the collection bin. I had expected the morning to be mainly about removing rubbish, but the record sheets mattered too: they would help the group compare different sections of the beach at its next survey.
