Plastic fragments; this site was remarkably clean considering its' massive appeal to tourists and the general Ghost Gear problem in the surrounding bay.

Plastic bags

Food wrappers


As there was relatively little debris, we had time to deduct the weight of the bags (which we don't usually do), for a more accurate debris weight. We were happily surprised at the cleanliness of this sight. We know that there is a lot of Ghost Gear out in the Bay and it is one of Cornwall's most iconic tourist destinations. So, it was lovely to find it so relatively unscathed. As the Debris Dive took place from the harbour steps, and there is no beach to speak of, we did not conduct a beach clean on this occasion. We did note that the shoreline looked to be free of debris.
