## 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 INPE’s 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.

## June 6, 2006: 8S-30W PIRATA SWE ATLAS buoy adrift!...

- June 6th, 2006: the 8S, 30W PIRATA SWE ATLAS buoy starts to drift.
- Exchange of e-mails among PMEL-INPE-DHN takes place;
- Emergency recovery mission is setup between INPE and DHN, with real-time buoy positioning info by PMEL.
- June 28th, ATLAS buoy recovered by DHN’s ship Amorim do Valle.
- Buoy sensors & electronic already shipped to PMEL.
- _“__Causa Mortis”_: Nylon rope teared off.
