RISET DAMPAK PERUBAHAN IKLIM GLOBAL
DENGAN MENGGUNAKAN ARGO FLOAT
Kerjasama Riset BRKP 1) dan CSIRO Marine Research 2)
General Discussion

2. Argo Float
Instrumentasi yang
akan bergerak
mengikuti arus
bawah laut untuk
memperoleh data-
data oseanografi di
banyak lokasi sesuai
dengan pergerakan
arus bawah laut

3. Components of Argo Float:
• Satellite antenna
• CTD sensor
• Satellite Transmitter (Using GTS
satellite for data transmition from
float to receiver station)
• Air pump / valve
• Hydraulic pump (piston)
• Hydraulic oil
• Pneumatic bladder
• Lithium battery

4. Profiling float mission
Target float coverage
3000 floats
1 per 3º square

5. Argo coverage is 57.07% of target
(Updated March 2005)

(Malaysia International Shipping Company)

14. Photos Documentation (2)
8 Argo Floats APEX in boxes

15. Photos Documentation (3)
Find & remove the float from boxes
according to Hull number &
coordinate position for deployment
Reset the float for 3 second
using magnet

16. Photos Documentation (4)
Ensuring the hydraulic pump working
& also transmission to satellite was
good
Remove the plastics bags which
covering CTD sensor

17. Photos Documentation (5)
The Bladder empty means it’s not ready The Bladder full means it’s ready

18. Photos Documentation (6)
Put the Float in deployment sling then deploy from stern

19. Photos Documentation (7)
Lower the float over the stern then release
when it almost at the sea surface

20. Pengolahan data:
• Analisis Spektral Terhadap Data Tekanan, Temperatur &
Salinitas dari Argo Float dan Data Pasang Surut untk
Melacak Kejadian Tsunami Aceh 2004 (Achmad
Solechan & Agus Supangat)
• Studi Variabilitas Termoklin di Perairan Indonesia:
Selatan Jawa (Mayang W.A.R.I, Widodo S. Pranowo)
• Pelaporan & publikasi riset (Bagus Hendrajana, T.
Rameyo Adi, Semeidi Husrin, Rizki A. Adi)
