Summary
Results of lipid biomarker concentration and compound specific isotopes analyzed from authigenic carbonates and surrounding sediment collected from Baltimore and Norfolk seep fields along the United States Atlantic Margin are presented in csv format. Samples were collected by the U.S. Geological Survey and Duke University between 2012 and 2015 using remotely operated vehicles (ROVs). Geochemical analysis was performed using gas chromatography (GC) and GC-combustion isotope ratio mass spectrometry (GC-C-IRMS).

Purpose
The purpose of making these measurements was to identify what microbial communities are driving anaerobic oxidation of methane at the Norfolk and Baltimore seep fields. The identification and distribution of these microbial communities represents a key component to understanding the global methane cycle including both short- and long-term methane storage.
