Congratulations to "SoilSedHead" lab member, Lance Stewart, on his upcoming graduation! Lance will be joining the Soil-Sed-Human lab this fall where he will be researching Tennessee River paleofloods.
Check out our latest publication (Stinchcomb et al., 2016) to learn more about a new model to reconstruct past climates using ancient soils (paleosols) and explore the how the model predicts precipitation and temperature here and below!
SedSoilHuman lab student, Lance Stewart, spends a week working with Baylor University's SQUID magnetometer, housed in Dan Peppe's lab. Lance was preparing and analyzing paleomagnetic samples collected from the Chalbi Desert in Northern Kenya. We hope to observe geomagnetic reversals that will help fix the Chalbi stratigraphy in time. Learn more here about SQUID magnetometers and Geomagnetic Reversals.

Pictured here with their mentor (Gary Stinchcomb), Ashley and Lance are geoscience majors and McNair scholars working in the SedSoilHuman Lab. To learn more about their current and future work, check out the lab page! Congratulations, Ashley and Lance, for all of your superb efforts!
The sedsoilhuman lab had a good showing at this year's Kentucky Water Resources Annual Symposium in Lexington, KY with two poster presentations:
Buried soils are an important control on C storage along human-impacted floodplains in Kentucky, USA, Ashley Casselberry and Gary Stinchcomb, Dept. of Geosciences and Watershed Studies Institute, Murray State University
Buried soils are an important chemical interface controlling mineral weathering and solute gradients along river corridors, Gary Stinchcomb, Ashley Casselberry and Abbigail Smith, Dept. of Geosciences and Watershed Studies Institute, Murray State University
Below is a pick of Ashley discussing her work with scientists from the Daniel Boone National Forest, Dr. Claudia Cotton (soil scientist) and Jon Walker (hydrologist). Also, check out the sweet oola life VW van we spotted in the hotel parking lot.
McNair scholar and Murray State geoscience student, Ashley Casselberry, presented her research at this year's GSA in Baltimore, MD USA. Her work, titled, "Buried soils are an important control on C storage along human-impacted landscapes in KY, USA" was well received! Way to go, Ashley

Greg Lattanzi and Gary Stinchcomb recently published their isotope analyses of Abbott Farm NHL museum-archived samples. Check out the link and abstract below to learn more!
Lattanzi, G. D., Stinchcomb, G. E., 2015, Isotopic analysis of museum-archived soil samples from archaeological sites: A case-study using the Abbott Farm National Historic Landmark, USA: Journal of Archaeological Science: Reports 4, 86-94, doi:10.1016/j.jasrep.2015.08.044
Abstract: Archived soil samples hold important information for reconstructing ancient environments and can provide data on prehistoric land use, manipulation and changes over time. Archeological investigations at the Abbott Farm National Historic Landmark (NHL) located near Trenton, New Jersey recovered occupations from Paleoindian to Late Woodland periods. Soil samples collected during the 1930s WPA excavations have never been analyzed until now. This paper discusses the results of a carbon isotope analysis of soil organic carbon, δ13Csoc, performed on 54 samples from a number of archeological contexts from the Abbott Farm NHL. Data from Early and Middle Woodland pits and associated soils exhibit average δ13Csoc values of − 25.0 ± 1.0‰ suggesting that the suite of samples have an isotopic signature that primarily reflects aboveground C3vegetation. These values agree with current interpretations of an Early and Middle Woodland that had no maize and a gradual Late Woodland introduction of maize (C4plant) into the Lower Delaware River Valley. Assuming these samples have not experienced significant organic matter oxidation in their ~ 80 years of storage, the Abbott Farm results suggest that preserved archeological feature and soil samples in other collections that have been desiccated and housed in climate controlled facilities serve as an untapped resource for paleoenvironmental reconstruction for sites that either no longer exist or where access is limited. In the case of Abbott Farm NHL, the archeological feature and soil samples provide information on prehistoric site vegetation and paleoenvironment before the beginnings of agriculture in the Delaware Valley.
