Microplastic Concentration in Snow Samples from Ross Island, Antarctica, 2019

We collected a total of 19 samples were collected with 6 from locations near research stations and 13 from remote locations with minimal human disturbance across the Ross Island region of Antarctica. Samples were collected using a stainless-steel scoop and stainless-steel funnel to fill each 500 mL bottle with snow from the top 2 cm of the surface. Suspected microplastic particles were isolated and their composition confirmed using micro-Fourier transform infrared spectroscopy (µFTIR). Concentrations are provided as microplastic particles per litre. Further details are provided at https://doi.org/10.5194/tc-16-2127-2022
