Grant Details

Description

New methods, technology, software, and instruments are being developed that require updating research methods in wetlands. A variety of well and piezometer diameters and packing materials will be tested in problematic clayey wetlands with very slow lateral and vertical hydraulic conductivity. Studies of soil carbon balances in peatlands of Russia have been proposed for members of this research team. If funded, the research will allow improved methods of using IRIS tube technology for detecting reducing conditions in suspected hydric soils. Carbon balances in peatlands under differing land uses will allow projection of regional carbon fluxes in a critically-important worldwide ecosystem that has a very large proportion of the earth's unfrozen soil carbon. As the peatlands warm, they are expected to be used more intensively than before, releasing excess carbon dioxide and methane from advanced organic matter decomposition. New sources of imagery now allow testing methods of detecting soil water, carbon, and clay contents, needed to help identify location and boundaries of wet flats in coastal plains, a major type of wetland under severe pressure for agricultural use and development if drained previous to 1985 or if modified without permit while undetected on inventory maps. LiDAR shows particular promise for developing a new precision of elevation maps not available before.
