Observation

 

  1. High chlorophyll a concentration along the coast of Sarawak was possibly due to the higher rainfall that increased of the river discharge that induced nutrient flux in the coastal water. However, the chlorophyll a content could be over-estimated due to the turbid water.
  2. Phytoplankton chlorophyll a concentration at area close to river mouth is expected to be over-estimated.
  3. The increment of chlorophyll during Jan 2004 along the west coast of Sabah was evident.
  4. Higher rainfall at the east of Sabah in December 2003 could contribute to the increase of chlorophyll a in Jan 2004.
  5. Higher chlorophyll a in Brunei Bay was probably due to turbid water.
