Biogeochemical responses of the cryosphere to environmental change
Biogeochemical responses of the cryosphere to environmental change
Session ID#: 123057
Session Description:
The cryosphere (glaciers, frozen ground, snow and sea ice) is responding disproportionately to climatic change due to its sensitivity to increasing temperatures. As a result, intensifying hydrological regimes and changing fluxes of sediments, carbon and nutrients from the cryosphere to other freshwater and marine environments are impacting biogeochemical processes at local to global scales. In this session, we focus on micro- to macro-scale cryosphere-biogeochemical linkages under past, present and future environmental change. This highly multidisciplinary session aims to bring together a diverse range of scientists with interests spanning microbiology, biogeochemistry, glaciology, hydrology and oceanography of the coldest places on Earth to debate our current understanding and recent advances. We encourage contributions that provide insights into elemental cycling, contaminant transport, organic biomarkers and microbial community composition and feedbacks in the cryosphere. We particularly welcome contributions linking biogeochemical cycling in the cryosphere to other components of the Earth system.
