Argo Float - akses data

Apa itu Argo Float, bagaimana ceritanya, dimana persebarannya, untuk apa ya ???

Munculnya Argo Float merupakan sebuah konsep revolusioner dalam sistem observasi kelautan dan metode pengukuran global. Argo Float merupakan instrumen yang bergerak mengikuti arus bawah laut yang disebar di lautan terbuka dengan resolusi spasial kira-kira 300 km. Selama satu kali dalam sepuluh hari akan muncul ke permukaan di akhir tiap siklusnya dan mengirimkan data ke satelit komunikasi (misalnya: satelit ARGOS)

Argo Float - silahkan akses data Argo Float...bisa dilihat Argo yang telah matidan yang masih hidup di http://www.marine.csiro.au/~gronell/ArgoRT/select_floats_WMO.html

Untuk akses data Argo kini cukup mudah..dan enak dilihat euy..karena memanfaatkan google earth..

What is Argo? Argo is a global array of 3,000 free-drifting profiling floats that measures the temperature and salinity of the upper 2000 m of the ocean. This allows, for the first time, continuous monitoring of the temperature, salinity, and velocity of the upper ocean, with all data being relayed and made publicly available within hours after collection.

Positions of the floats that have delivered data within the last 30 days (AIC, updated daily):

Why do we need Argo? We are increasingly concerned about global change and its regional impacts. Sea level is rising at an accelerating rate of 3 mm/year, Arctic sea ice cover is shrinking and high latitude areas are warming rapidly. Extreme weather events cause loss of life and enormous burdens on the insurance industry. Globally, 8 of the 10 warmest years since 1860, when instrumental records began, were in the past decade. more information...

Where is Argo now?

Argo deployments began in 2000 and by November 2007 the array is 100% complete. Today's tally of floats is shown in the figure above. While the Argo array is currently complete at 3000 floats, to be maintained at that level, national commitments need to provide about 800 floats per year (which has occurred for the past three years). more information...

Who Collaborates with Argo?

Argo is a major contributor to the WCRP's Climate Variability and Predictability Experiment (CLIVAR) project and to the Global Ocean Data Assimilation Experiment (GODAE). The Argo array is part of the Global Climate Observing System/Global Ocean Observing System GCOS/ GOOS).

Pada 19 Maret 2009, saya menerima email dari
Dr Tseviet Tchen
CSIRO Marine and Atmospheric Research

mengatakan bahwa ada info baru di blognya Argo... :

" Regarding Argo, there is a new thread to its blog about the Argo outreach effort, to which you may want to contribute. "

Argo outreach resource

In line with the Argo outreach effort, CSIRO has been hosting a web-page which provides weekly updated T/S profiles for the global Argo array:

http://www.marine.csiro.au/~ttchen/argo/gmap.htm, with specific characteristics as follow:

* national grouping for floats localisation
* low-cost hardware requirements for web-access, ie access is via GoogleMap which requires no high-speed graphic card, in contrast to Google Earth.

Usage: hovering the mouse-pointer over the icon of a float brings up a menu which lists clickable links leading to float information, such as TS-plots.


More detailed real-time data are available for the Australian floats at http://www.marine.csiro.au/~gronell/ArgoRT/select_floats_WMO.html


You are most welcome to explore this resource and to feedback any comments.


Tseviet Tchen.
