RAMA Buoy in the

Northern part of BOB:

Monitor CO2 in air and

seawater

(CO2 sensor was support

BOBLM)

Expectation:

1. To understand the Status of acidity of

seawater in Thai.

2. To understand the chemical property

of seawater chemistry (especially

acidity) around vicinity of coral reefs

3. To develop and increase research

capability on the ocean acidification in

Thai waters

4. To develop the long term monitoring

and studies on ocean acidification

and its impacts on marine ecosystem

in Future
