[A-HW18] Material transportation and cycling at the land-sea interface: from headwaters to the ocean

Fri. May 26, 2023 1:45 PM - 3:00 PM 105 (International Conference Hall, Makuhari Messe)

convener:Takahiro Hosono(Faculty of Advanced Science and Technology, Kumamoto University), Syuhei Ban(The University of Shiga Prefecture), Mitsuyo Saito(Graduate School of Advanced Science and Engineering, Hiroshima University), Adina Paytan(University of California Santa Cruz), Chairperson:Syuhei Ban(The University of Shiga Prefecture)


This session aims to synthetize watershed-based sciences to better understand dynamic processes in transportation and cycling of materials and nutrients at the land-sea interface from headwaters to the ocean via rivers, groundwater, and coastal lakes. The session will integrate research from various disciplines including limnology, groundwater hydrology, geochemistry, coastal oceanography, meteorology, soil science, sedimentology, forestry, agriculture, fishery, ecology, social science, and other related fields. This session calls for sharing new methods such as tracers and molecular techniques, machine learning, watershed modeling, microbial and paleontological approaches, and chemical analyses that help to elucidate physical, chemical, and biological mechanisms in terrestrial-aquatic ecosystems. Moreover, it seeks to shed light on the complex and dynamic terrestrial-aquatic systems and their spatio-temporal variations in a changing climate and environment. Laboratory-based and field-based studies, social and socioeconomic evaluation of ecosystem services and social-ecological systems are also welcomed. Through this session, we would like to facilitate interdisciplinary collaboration among participants to create a new watershed-based science that considers the overall interrelationship between headwaters and the ocean.
