During the 38th Chinese National Antarctic Research Expedition in 2021–2022, surveys on oil, microplastics and persistent organic pollutants (POPs) in waters and sediments were conducted in the Antarctic Peninsula, Prydz Bay and Ross Sea. This work aims to understand the pollutant distribution in these areas from multiple perspectives, reveal the distribution characteristics, major sources and migration pathways of polar pollutants, assess the environmental impacts and ecological effects of pollutants in the Antarctic region, and provide research foundations and technical support for China in addressing international marine pollution issues.

This dataset contains the sediment microplastic analysis data collected during the 38th Chinese National Antarctic Research Expedition (2021–2022). The data includes sampling station, longitude, latitude, date, water depth, shape, color, particle size, composition and other related information.

1. Sample Collection Equipment
(1) Box corer
(2) Surface seawater microplastic sampler (Manta net) and pump filtration microplastic filter

2. Observation Methods and Obtained Data
Microplastic samples were analyzed using Fourier Transform Infrared Microscopy (FTIR microscopy).

3. Observation Areas
The survey areas during this cruise are the waters of the Antarctic Peninsula, Prydz Bay and Ross Sea.
