Stable Isotope Biogeochemistry
Congrats to Martin Kurek who recently published his undergraduate research project in Chemical Geology. We developed a method to use a reducing agent (DTT) to extract elemental sulfur. Nice job Martin! You can download a full copy of the article from the following link for free until April 13, 2018. Kurek et al., Chemical Geology, 481:18-26, 2018.
Check out our films method that was published in Marine Chemistry.
We demonstrate that photographic film can capture the spatial concentrations and stable isotope compositions of dissolved sulfide from water columns and pore waters. These films can be used in a wide variety of environments such as our study of the highly dynamic production and oxidation of hydrogen sulfide in the mud of the seagrass meadow shown below.
Check out our recent publication about nutrient cycling in dryland soils.

I’m so stoked that our lab group just published “Midcontinental Native American population dynamics and late Holocene hydroclimate extremes” in Nature Scientific Reports.
It seems like ages ago when we first collected our sediment cores from Martin Lake in 2013.
