Summary of PIRATA Brazil Activities during 2006

• 8S-30W SWE ATLAS buoy emergency recovery due to
  anchoring problems.
• Engine failure of R/V ANTARES prior to the PIRATA
  BR-IX backbone and SWE-II scheduled maintenance
  cruise in July 2006.
• Emergency servicing arranged by DHN, with special
  funding from MCT.
• PIRATA BR-IX and PIRATA BR SWE-II are now
  underway. 3 ATLAS moored are being serviced.
• PIRATA data collected, decoded, and made
  available by INPE during September 2005-August
  2006.
• PIRATA Laboratory at INPE/Natal Mechanical
  workshop civil constructions completed.
• ASPSP Tide Gauge acquired being integrated with
  INPEs automatic met station at CPTEC.

PIRATA BR-IX

• Current PIRATA BR IX Mission dates are October
  23 to December 15.
• CTD profiles at each degree of latitude along the
  38W meridian and along the PIRATA SWE array
  between 34W-19S and 30W-08S.
• ANTARES shall amostrate ADCP currents twice along
  the 38W meridian line, as a way to enhance the
  accuracy of currents measurements sampled by
  ANTARES ADCP.
• There shall be one radiosonde launch per day
  during the time at sea.

  and DHN, with real-time buoy positioning info by
  PMEL.
• June 28th, ATLAS buoy recovered by DHNs ship
  Amorim do Valle.
