Analytical measurements of nutrients in a mesocosm, a Long Term Oil and Particle Oxidation Study (LTOPOS)

This was a multiple mesocosm experiment where seawater that had been collected 8 km offshore south of Galveston (TX) and pre-treated with a charcoal filter to separate large particles were exposed to different treatments such as mixing with the oil slick, and DCEWAF (diluted chemically enhanced water accommodated fraction). Controls were also enacted. Samples for chemical analysis of particles were taken from the surface and bottom of tanks at specific time points. Nutrient samples were analyzed by Astoria Pacifica Auto-Analyzer.
