Anne Carey and her research group perform multi-disciplinary research based upon physical and chemical principles which draws upon expertise in quantitative physical hydrology and in biogeochemistry. Research areas include (1) the relationship between weathering and landscape evolution in the transport of solutes and sediments, primarily in small mountainous rivers; (2) the role of urbanization and of agriculture on water quality; (3) determination of geochemical mass balances on the watershed scale; (4) coastal aquifer dynamics; and (5) permafrost hydrology and the impact of climate change on water resources. Current research shows the importance of chemical weathering in the overall denudation of rapidly uplifting geologic environments and the need for mechanical weathering to produce fresh new mineral surfaces which can rapidly weathering chemically. Recent research on high-standing islands also shows small mountainous rivers to be important sources of dissolved and particulate organic carbon to the world’s ocean. The group’s research involves important, international collaborations which Carey has developed with colleagues in New Zealand, Taiwan, Philippines, and Nicaragua. Carey has had external funding for her research from the National Science Foundation and the Department of Energy.
