Science Objectives

The Pioneer 3 Leg 1 deployment cruise (Pioneer-3a) has 13 primary objectives that include the recovery and deployment of Profiler Moorings, the deployment of gliders, and CTD casts with water sampling at the mooring sites. The Pioneer-3a cruise also has additional objectives, including multi-beam bathymetry surveys of the Pioneer region and CTD/ADCP surveys in the vicinity of the Pioneer moored array.

Science Activities

The R/V Knorr will depart from Woods Hole and transit to the Pioneer Offshore site where operations will commence. Successive days will include either two mooring operations (deployment and recovery) or one mooring deployment and one glider deployment. CTDs with bottle samples will be done in conjunction with the mooring turns. Glider deployments will be interspersed with mooring operations at times and locations chosen for efficiency. Multibeam surveys and ADCP surveys will be conducted in late evening after mooring and glider operations are completed. A detailed timeline is provided in Appendix A.
The primary Objectives (O1-O13) are listed below. Nominal times for these activities are given in the cruise timeline (Appendix A). Site locations are listed in Appendix B.
  • O1. Recover the Upstream-Inshore Profiler Mooring (CP02PMUI-00002).
  • O2. Deploy the Upstream-Inshore Profiler Mooring (CP02PMUI-00003).
  • O3. Recover the Upstream-Offshore Profiler Mooring (CP02PMUO-00003).
  • O4. Deploy the Upstream-Offshore Profiler Mooring (CP02PMUO-00004).
  • O5. Recover the Central Inshore Profiler Mooring (CP02PMCI-00001).
  • O6. Deploy the Central Inshore Profiler Mooring (CP02PMCI-00002).
  • O7. Recover the Central Offshore Profiler Mooring (CP02PMCO-00001).
  • O8. Deploy the Central Offshore Profiler Mooring (CP02PMCO)-00002).
  • O9. Recover the Offshore Profiler Mooring (CP04OSPM-00001).
  • O10. Deploy the Offshore Profiler Mooring (CP04OSPM-00002).
  • O11. Deploy two shallow (200 m engine) coastal gliders (EB, FZ-2).
  • O12. Deploy three deep (1000 m engine) coastal gliders (FZ-1, SS-1, SS-2).
  • O13. Conduct CTD casts with water sampling at the mooring sites.
There are also Additional objective  that would be desirable to accomplish on the cruise. The Additional objectives are listed in rough priority order, and will be completed as time and conditions permit.
  • A1. Conduct multibeam bathymetry surveys in the Pioneer region.
  • A2. Conduct a CTD surveys (no bottle samples) in the vicinity of the moored array.
  • A3. Conduct shipboard ADCP surveys in the vicinity of the moored array.
