Tidal currents in Te Pangu Bay, Tory Channel

Tidal currents were measured by a month-long deployment of an ADCP seaward of the existing farm in Te Pangu over a neap-spring cycle. Results showed that while water flow was greater close to the mouth of Te Pangu, recirculation and eddies generated by adjacent headlands suggested there would be no significant advantages in moving net pens within the near vicinity once drag from the net pens was considered.

Purpose
This assessment provided background to the potential re-orientation or re-sitting of the marine farm in Te Pangu to enhance water flow through the net pens, generated by (potentially) stronger currents.
