EM122 Water Column Sonar Data Collected During AT26-06

Submarine Exploration and Evaluation of Petroleum Seeps (SEEPS) (AT26-06, EM122). 1. Conduct in-situ incubations with devices for microbial growth, deployed in 2011.
2. Investigate the fate of dissolved hydrocarbons in the waters along the CA margin.
3. Investigate the variability in composition of seeping hydrocarbons at sites along the CA margin.
4. Investigate the distribution and nature of hydrocarbon seepage and biodegradation along the CA margin.
5. Identify and map hydrocarbon/tar sources and related features along the CA margin.
6. Identify, map and sample microbes and chemicals associated with historical waste disposal practices.
7. Conduct sampling for additional in-situ incubations.

Distribution Formats
  • >Kongsberg EM122 raw files (Version:1)
    • File Specification: Kongsberg/Simrad .raw files are generated by ME70, EK60 or ES60 instruments. They contain power and optionally angular position data with each beam/frequency identified by an independent channel. See the Simrad interface specification manual for further information. The .wcd files are generated by Kongsberg EM302 or EM122 instruments. See Kongsberg documentation for more information.
