Henko de Stigter

Henko de Stigter is a marine geologist and active researcher at the Royal Netherlands Institute for Sea Research (NIOZ), focusing on the Ocean Systems department. His work centers on the ecological and geological impacts of deep-sea mining, particularly concerning manganese nodule harvesting.

• Role: Researcher
• Key Research Themes: Deep-sea mining, sediment dynamics, methane leakage, organic matter distribution, and environmental mitigation strategies.

De Stigter investigates the long-term ecological consequences of deep-sea mining, such as sediment plumes and habitat destruction, which could take millennia to recover. His recent publications address methane emissions from abandoned wells, sedimentary records of Nile-derived mud, and organic pollutant distribution in marine shelf environments. These studies highlight interdisciplinary approaches combining geology, oceanography, and environmental science.

His research trends focus on anthropogenic impacts on marine ecosystems, sedimentary processes, and resource sustainability. This aligns with projects like TREASURE and NSME, which aim to develop responsible mining practices and methane emission monitoring frameworks.
