Explanation of Science Party Requirements and Technician Requirements |
Min. 2 marine techs required, one trained in processing of EM302 swath bathymetry data. Essential that this be done onboard during cruise in order to provide quality control of data acquisition during expedition. |

|
Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
EM302 swath bathymetry system required. 3.5 kHz and 12 kHz seismic profilers, 24 Niskin bottle rosette and CTDs wiht oxygen and particle sensors.
|

|
Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
JASON II is required plus their instrument vans, crane, and winch. Two "elevators" are requested for transport of instrumentation to/from seafloor. OSU multi-corer is required and will be modified with thermistors mounted on one core barrel. |
