Science Mission Task 4.4: Multidisciplinary seafloor observatory trials in the vicinity of the Poseidon-Pylos cable   

Tasks:

  • To perform two surveys from 1000-5500m in the vicinity of the Poseidon-Pylos cable and
  • Analyse images and environmental data from surveys.
  • Combine data with existing data from other disciplines (e.g. seismic, geological, organic matter).
  • Produce report identifying potential sites for permanent observatory.
  • Perform concentrated observations at potential sites for permanent observatory.
  • Analyse images and environmental data from concentrated survey.

The various observational objectives of Task 4.4 were completed over 5 research ship cruises in August 2008, October 2008, May 2009, December 2009 and January 2011.
A baited automatic camera system was used to take images which will be used to estimate fauna abundance at potential sites for a neutrino telescope.
Some of the images are shown below. Click on an image to see a larger version.
Further surveys were carried out using Remotely Operated Vehicles (ROVs), as well as CTD profiles measuring water properties.
