The remotely operated vehicle Ventana was used to measure the vertical distribution and the optical characteristics of suspended layers of fine particles along the axis of Monterey Canyon in Monterey Bay, California. A combination of a nephelometer, a transmissometer and a structured light source with high definition video detection was used for these measurements. The particles layers ranged from broad bands extending over several hundred meters of depth to thin, concentrated layers <20 m thick. Ventana was also used to collect water samples, without the physical disruptions inherent in CTD/rosette-based sampling, within and around the particle layers. Samples were collected from depths of 400 - 1450 m and are being analyzed for methane, methane carbon stable isotopes, alkalinity, nutrients, thorium isotopes, and pH. In addition, video of the structured light transects were analyzed to determine particle size distribution and collected particles were analyzed for mineral and chemical composition. Finally, genomic characterization of the microbial communities on the collected particles will be conducted. General scientific contribution of the cruise: The results of this cruise will significantly increase our understanding of the importance of diagenetic processing in suspended particle layers, and how such processing affects the biogeochemical cycles of the upper ocean. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded NCEI Accession 0000902 was revised and a new version of the archival package was published.
