Sediment records provide an unparalleled archive of Earth's environmental history, preserving evidence of both natural events and human influences across millennia. This program proposes an interdisciplinary approach to investigate sediment layers, aiming to decode the history and impacts of natural hazards such as floods, landslides, and volcanic eruptions, alongside human-driven changes like deforestation, urbanization, and industrial pollution. By analyzing these layers and their geochemical and biological markers, we can reconstruct past events, revealing their frequency, intensity, and potential causes. This research will involve collecting sediment cores from carefully selected sites, including lake beds, river deltas, and coastal areas. Advanced dating techniques, such as Pb-210 and C-14, combined with highresolution analysis, will enable the identification of layers associated with specific historical hazard events and shifts due to human activity. These findings will enhance our understanding of past environmental dynamics and inform models for predicting future natural hazards in the context of climate change and shifting land use. Participating students will gain hands-on experience in sediment coring, microfossil identification, isotope dating, and geochemical analysis, equipping them with valuable skills for careers in environmental science and hazard assessment. This program aims to contribute to more resilient environmental planning and disaster preparedness.
