The seabed debris

We used Naturalist’s rectangular dredge to collect samples of seabed debris along Taiwan’s west coast from 2019 to 2022. There were eight sites with an average depth of 10- 30 meters. Among the results, the samples from Donggang River estuary in Pingtung County had the highest dry weight (2,543 g), accounting for 48% of all samples. Fiber fabrics (58%) and film plastics (33%) accounted for the largest proportion of all samples, and fiber fabrics from Gaoping River estuary (83%) and Donggang River estuary (75%) accounted for more than 70% of all samples at each site. However, there were no significant differences in the proportions of wastes in different quarters. This study monitors the distribution and composition of underwater trash over a long period of time.
