Anthropogenic pollution in deep-marine sedimentary systems -- A geological perspective on the plastic problem
Ian Kane & Andrea Fildani, Geology Plastics & Pollution
While surveying a deep-marine canyon to examine seafloor bedforms, Zhong and Peng (2021, p. 581 in this issue of Geology) made a shocking discovery. The results show large litter piles (mostly plastic) closely associated with geomorphological features of the nearly 2-km-deep canyon floor. While this is not the first paper to document trash on the seafloor (e.g., Goldberg, 1997; Thompson et al. 2004; Pham et al. 2014), the spatial distribution of these piles, constrained by high-resolution geologi-cal and geomorphological data, allow inferences to be made of the flow processes responsible for transporting and depositing the waste.
