048 Highly permeable benthic habitats in a time of environmental change
Highly permeable sand and gravel deposits that often dominate freshwater, coastal and continental shelf ecosystems allow extensive exchange of fluids, solutes and particles. The methodological challenges posed by the study of these dynamic benthic habitats have stimulated interdisciplinary investigations employing a multitude of different approaches and tools, including remote sensing, sampling with conventional techniques and novel sensors, in situ and laboratory experimentation, and modeling. Recent work has resulted in significant advances in our understanding of highly permeable aquatic habitats in ocean margins, lakes, rivers and streams. Yet, the interchange of knowledge between surface water hydrologists, limnologists, and oceanographers working on permeable benthic habitats is limited. This session aims to showcase studies on permeable marine and lacustrine sediments, the hyporheic zone of rivers and streams, and the influence of surface water/groundwater exchange-driven processes, in order to promote the cross-pollination of approaches, methodologies and ideas between studies and habitats. We especially welcome interdisciplinary and/or integrative studies, and research addressing the impacts of climate change (e.g., changing precipitation and temperature patterns, rising atmospheric carbon dioxide) on vulnerable permeable benthic habitats (e.g., seasonal streams, ice-covered marine and freshwater systems, and calcareous reef sediments) and the species that help define them.
