Summary of Field Work: |
The proposed observational experiment is to study isopycnal spectra and stirring on the submeso- and finescales. The primary platform is a 200-m long towed chain equipped with 60 CTD sensors with realtime data capability. The experimental site is within the box of 125-130W, 30-35 N. The experiment will be conducted in summer of 2018. |

Explanation of Science Party Requirements and Technician Requirements |
We will conduct 24 hours operation and therefore 2 Restechs will be preferred. |

|
Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Shipboerd ADCP is needed for making velocity measuremetns. 300kHz ADCP is preferred. If not, we will bring our own 300kHz ADCP. Dynamic positioning will be preferred for the hove to operation. We also would like to have an additional 75kHz ADCP for providing deeper velocity information.

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
TSE winch is needed for the towed CTD chain operation. Towed point for the towed cable. |
