SST and coral bleaching

update for yesterday n today.
------------------------------

yesterday i do some background reading on coral bleaching and SST.
i understand the concept of both case study..
but what spinning me around is how does the SST data extracted?
i mean, the data processing.
what is the raw data for SST?
are the colourful classified satelite images is the product of combination of SST observation from satellites and thermometer ?(since there is various type of SST and sources)
or is there any satellite that can detect the temperature without needing any processing process?
after long days of reading (plus sleepy cuz fasting)
i find nothing except the example of applied arc marine data model (which solve my one entangled misunderstanding issue)

ok, today i found 1 article from australia govt which give answers for my unpleasant understanding of SST.

and this is part of it (which makes me write this update -->improvement)
Sea Surface Temperatures (SSTs) maps derived from remote sensing by satellites have been available since the 1970s. The Bureau currently uses measurements from the Advanced Very High Resolution Radiometer (AVHRR) on board the National Oceanic and Atmospheric Administration NOAA series of polar orbiting satellites to derive SSTs for the Australian region. The data is calibrated and quality controlled against SST data collected from ships and drifting buoys. The SSTs are used in real time operations and also archived as the data as part of Australia's National Climate Record.
ok, since i have the answer for my dilemma, now i can proceed to search info about the data processing (procedure and software) and find some public data + open source software!

c u l8r.

coral bleaching is like broke-up thingy (which leads to self-destroy effect) between coral and symbiotic algae. i wrote it down on blue book!
