Microplastics abundance in seawater and sediment collected in the Hangzhou Bay, China, during 2020-09-11 to 2020-11-21 (NCEI Accession 0280922)

공공데이터포털

This study estimated the concentration of microplastics (i.e. plastics measuring less than 5mm) in seawater (reported in unit of items/m3), and sediments (reported in unit of items/kg d.w.), in the Hangzhou Bay, China during 2020-09-11 to 2020-11-21. Microplastics in the seawater were collected using a plankton net while those in the sediment were collected using a sediment grab sampler. Data on hydrologic conditions in the study area were also collected. These include water depth (reported in unit of m), seawater temperature (reported in unit of oC), seawater dissolved oxygen (reported in unit of mg/L), seawater pH, and seawater salinity (reported in unit of ‰). This dataset contains the results from all 26 seawater, and 26 sediment samples, in a spreadsheet format.
