Our team of undergraduate students, graduate students, and research scientists are sampling for one week each month at Old Woman Creek National Estuary Reserve, taking more than 100 soil cores of the course of the summer. In the field, we are measuring dissolved oxygen and green house gas emissions. Back at the lab, we are measuring iron, nitrate/nitrate, acetate, and total organic carbon from soils collected in the field. We are also extracting DNA and RNA from each sample for single gene, metagenomic, and metatranscriptomic analyses.
