GC MS data for bottom particle dichloromethane extracts from the COAST, a COASTAL water mesocosm experiment amended with microbial concentrate

Mesocosm experiments were performed as part of the ADDOMEx GOMRI funded program with seawater collected from the NGOM and “seeded” with microbial populations collected from coastal Texas (in Galveston Bay). Aggregate materials that formed between days 2 and 4 of the experiment in control, WAF, DCEWAF, and CEWAF treatments and sunk to the bottom of mesocosm tanks were collected at the end of the experiment. The particles were extracted using dichloromethane. Dichloromethane extracts were diluted with methanol and analyzed using one dimensional and two dimensional gas chromatography mass spectrometry (GC-MS). Only DCEWAF treatment particles produced spectra with sufficient GC-MS signal to noise to archive here. The GC-MS data contained in the .csv file datasets represent the time elapsed after sample injection and the corresponding spectral response at the mass (or mass range) of interest that were obtained directly from the ChromaTOF software. The .jpeg files represent the spectral response (as generated by the ChromaTOF software) for the one-dimensional and two-dimensional GC-MS runs.
