Marjorie S Schulz
Marjorie Schulz (Jorie) is a scientist emeritus with the Geology, Minerals, Energy, and Geophysics Science Center. Since joining the USGS in 1987, Jorie has worked in several USGS programs; Marine Geology, the National Research Program of Water Resources, and now GMEGSC.
Jorie does multidisciplinary work built on a foundation in geology. She now describes herself as a biogeochemist with a bit of soil science. Her work has included research on manganese deposits on the ocean floor, mineral weathering, soil development, and geochemistry. Jorie is currently studying the interaction of organic matter (carbon) with soil minerals to understand the processes that stabilize soil carbon.
