Dr. rer. nat. Zhiyong Xie
His research interests focus on biogeochemistry processes of legacy and emerging organic contaminants in the global ocean, including long-range transport via atmosphere and ocean currents, air-sea/ice exchange, and bioaccumulation in marine food web. He has carried out pioneering research for emerging organic contaminants in global ocean, especially in the Arctic and Antarctic. With novel sampling and modern instrumental strategies, he develops effective analytical methods for discovering new chemicals with emerging concern in polar regions. He use model simulations to elucidate the biogeochemical cycle of the legacy and emerging organic contaminants in polar regions driven by changing climate and enhanced human activities.

Long-range environmental transport and biogeochemical cycling of legacy and emerging organic contaminants in global ocean and polar regions, impacts of human activities and climate change. Changing Earth - Sustaining our Future, projects relating to programme-oriented funding 2021 - 2027 (PoF IV), Helmholtz Association.
2018 - 2021 EISPAC

Effects of ice-associated stressors and pollutants on the Arctic marine cryosphere The overarching aim of EISPAC is to evaluate whether ice-associated contaminants serve as stressors on ice habitat functioning in relation to cryosphere dynamics and in comparison to the behavior of key nutrients. In essence, EISPAC will determine the magnitude and timing of exposure of contaminants to sentinel, ice associated organisms and their effect on the lower marine food web, seeking to examine processes that control pollutant and key nutrient entry, accumulation and transfer within the sea ice system in the Arctic.

Integrative and Comprehensive Understanding of Polar Environments. iCUPE is an ERA-Planet (European Network for observing our changing planet) thematic strand 4 (Polar areas and natural resources) Project.
By combining integrated in-situ and satellite observations with a modelling platform, iCUPE will synthesizes data from comprehensive long-term measurements, intensive campaigns and satellites, collected during the project, or provided by on-going international initiatives; relates the observed parameters to impacts, and delivers novel data products, metrics and indicators to the stakeholders concerning the environmental status, availability and extraction of natural resources in the polar areas. The project improves understanding of the pollution sources and sinks, environmental and anthropogenic changes and elements of the cryosphere in polar areas by conducting high-level and high impact research by analyzing these integrated data together with the modelling frameworks.

2011 - present ePOPARCTIC

Long-term investigation of emerging persistent organic pollutants in the Arctic. This project is one of the long-term research programs established at AWIPEV research base in Ny-Alesund, Svalbard.
Atmospheric long-range transport is a significant route for organic contaminants to reach ecologically sensitive Arctic environment. Organic pollutants are subject to a variety of processes in the Arctic environment such as degradation, bioaccumulation and interaction between the atmosphere, snow, water and soil. Furthermore, climate change may significantly influence the transport and environment fate of organic pollutants in the Arctic. This project is focused on studies of long-term trends and atmospheric transport of emerging persistent organic pollutants in the Arctic. Data and feedback from this project may improve models to predict the environmental progression and assess the effect of climate change on the long-range transport and the fate of the emerging organic contaminants in the Arctic ecosystem.
