The biogeochemical cascade and impacts of climate warming from the cryosphere to the ocean in high-latitude regions

Session ID#: 257888

Session Description:
High-latitude cryosphere-land-ocean interfaces are highly sensitive biogeochemical hot spots linking terrestrial and marine systems, and represent a logical region for examining climate change impacts on land and implications for receiving ecosystems. The geochemical composition of freshwaters draining watersheds represents an integrated signal of all processes occurring within the catchment (e.g. glacial retreat), and therefore is impacted by climate. We solicit contributions that consider molecular to estuary/fjord and watershed scale processes with respect to understanding both organic and inorganic geochemical dynamics and interactions at the cryosphere-land-ocean interface, and how these respond to and influence larger-scale processes. Research utilizing a suite of geochemical analyses, including natural abundance and radiocarbon isotopes, spectrophotometric techniques (e.g. absorbance, fluorescence), mass spectrometry (e.g. FT-ICR MS, MC-ICP-MS, ICP-MS/MS), NMR, and other characterization and isolation techniques to understand biogeochemical dynamics and elemental reactivity are encouraged. We seek studies utilizing these analyses to examine how the cryosphere and its linked marine systems are responding to human-driven environmental changes.
