This dataset contains two csv files. The first one
(South_Africa_Port_Durban_Microplastics.csv) reports the results of the study
carried out in the Port of Durban in 2019. The file contains water measurement
from CTD casts, microplastic abundance in water sampled by microplastic pump,
microplastic abundance in sediment and particulate size analysis (PSA) results
from Van Veen grab samples. GPS coordinates and time of deployment are
reported for each measurement. CTD measured temperature, salinity and
turbulence of the water. For microplastic pump casts, the amount of water
filtered, the size of the four sieves used and the number of particles found
on each filter are reported. Data from the grabs include PSA results and the
number of particles found in the replicates (5g each) from each grab with lab
blank values. A series of atmospheric blanks was also obtained leaving a jar
open during sampling operation and microplastics abundances are reported. The
csv second file (South_Africa_Port_Durban_Microplastics_FTIR) contains the
profiles of the ATR-FT-IR spectrum analysis of plastic pieces found in the
water samples. A .zip folder contains additional 18 FTIR profiles from water
samples for which only a .tif image is available. A README text file contains
the legend of the columns of the two csv files.
