Joanna J. Waniek is a Professor at the Leibniz Institute for Baltic Sea Research (IOW) in Warnemünde, Germany, where she leads the Bio-physical Interactions Group. Her research spans physical-biological processes across the North Atlantic, Baltic Sea, and South China Sea marginal systems, with current projects focused on microplastic dynamics and pollutant transport. She maintains active field work at deep-sea observatories including the long-term Kiel276 station (33°N, 22°W) established in 1980. Her primary research interests involve: Marine pollution mechanisms, particularly microplastics as vectors for persistent organic pollutants Biogeochemical cycling of carbon, nitrogen, and phosphorus in marginal seas Physical controls on particle flux and sedimentation patterns in deep ocean basins Anthropogenic impacts from megacities on coastal ecosystems (e.g., Pearl River Delta) Climate-driven changes in ocean circulation and their ecological consequences Analysis of her 2023-2025 publications reveals dominant patterns: 80% focus on Baltic Sea pollution dynamics (chlorinated hydrocarbons, microplastics in ice) 60% investigate South China Sea systems (Pearl River estuary, Kuroshio intrusion) Emerging emphasis on microplastic-biofilm interactions and pollutant vector behavior Methodological innovations in microplastic separation and quantification techniques Integration of 40+ years of Kiel276 time-series for climate impact assessment Waniek has secured major funding as principal investigator: NAPOLY: DFG project (WA2157/12-1, 2024-2027) on microplastic-POP correlations E-POLIO: BMBF project (03G0305TA, until 2026) examining Indian Ocean pollutants MEGAPOL: BMBF consortium (03F0786A, 2017-2020) on megacity fingerprints in Chinese seas Decade: DFG project (WA2175/5-1, 2011-2014) analyzing Kiel276 time-series SMIS: BMWi project (03SX348F, 2013-2016) developing deep-sea monitoring swarms She operates within IOW's Bio-physical Interactions Group, collaborating across physical oceanography, marine chemistry, and biological oceanography disciplines. Her work utilizes sediment traps at 2000m depth, expedition-based water column sampling (e.g., RV SONNE cruises), and partnerships with Chinese institutions including Guangzhou Marine Geological Survey and Shanghai Jiao Tong University for South China Sea research.
