Current Status
NODC or DNA No agency is officially assigned. Marine Research Section, GISTDA is currently working as a contact point.
Summary The process of setting up NODC or DNA is not an easy task and will take time. In the mean time, GISTDA can effectively play NODC or DNA's roles , provided that :
  • These roles are agreed and approved by GISTDA's board.
  • Limitations of personnals and funding are overcome.
  • Technical support is provided.
Southeast Asia START Regional Centre (SEA START RC)
Descriptions Southeast Asia START Regional Centre (SEA START RC) is an organization under Chulalongkorn University acting as non-government regional organization. START, the Global Change SysTem for Analysis, Research and Training, is a global network to encourage multidisciplinary research on the interactions of human and environment affecting and being affected by global changes. START is establishing regional network including Pan-Africa, Southeast Asia, South Asia, Temperate East Asia, Mediterranean, and Oceania. Geographically SEA START RC represents China Taipei, Vietnam, Lao, Thailand, Cambodia, Philippines, Malaysia, Singapore, Brunei Darussalam, Indonesia, and Australia.

Ship Measurements
Ship Measurements in the past After WWII - 1982 : 39 surveys in Gulf of Thailand and 1 in Andaman Sea
After 1982 ( with 2 new vessels) : 41 surveys in Gulf of Thailand and 5 in Andaman Sea
Routine Measurements 1 survey in Gulf of Thailand (90 days) and 1 survey in Andaman Sea (120 days) per year
Data Collected Temperature, salinity, conductivity, DO, pH, sediment data, current, meteorological data
Sampling Points Gulf of Thailand
Inner Gulf

Tide Guage
Descriptions Hydrographic department started collecting tidal height in 1904 at Bangkok Bar, located at the mouth of Cho Praya River. The first tide datum was calculated in April 1911. The subsequence 5-year water level from Ko Lak station was averaged and known as standard mean sea level of Thailand in October 1915. The Ko Lak 1915 datum is still used as standard mean sea level of Thailand though later studies showed that this is not truly the long term average.

After 1911, as Hydographic Department operated more and more tide guage, tidal observations became its responsibilities. Tidal data is also acquired from Port Authority of Thailand and Harbor Department. Hourly heights have been published for all stations.

Coastal Marine Processes
Descriptions Coastal marine processes are one of the most interested areas of study recently. In order to understanding better the coastal and near shore processes, data such as nearshore sediment, current, wave data, bottom topography, beach profile are utmost important. Hydrographic Department also has responsibilities in many beach and nearshore work including shore erosion protection, coastal construction, and environmental impact assessment study. In the latter roles, further data such as nutrient and heavy metal might be collected.
Oceanographic Data Management
Descriptions In 1997 the Oceanographic Division has initiated the oceanographic database with the responsibilities :
  • collect oceanographic data from contributors
  • develop quality control procedures
  • archive data in proper format
  • update data and maintain data consistency
  • contribute data in standard format and as requirement
  • develop on-line data and information exchange system
Data Archeology and Rescue
Descriptions Oceanographic data collected in the past is digitized, rechecked, and archived in database build around Access Database, which is used as data entry and a data management tool on personal computers. Until now, only hourly tidal height and 25-hour current observations have been checked and archived while other data are partially digitized.
WAM Modelling
Descriptions Outputs from WAM modelare placed on the web server at www.navy.mi.th/navymet/ , consisting of forecast of Significant Wave Height in Southease Asia and Thailand area. The forecast is for00, 12, 24, 36, 48, 60, 72, 84, and 96 Hr. Data from SEAWATCH Thailand is used for model verifications.

Routine Measurements
Details From 1997 : operates
  • 290 water collection stations
  • 105 soil sampling points at river mouth and coasts
  • 110 water sampling points at river mouth
  • water sampling in HAB area : 10 times/year
Coastal Oilspill Sensitivity Index
Descriptions Coastal Oilspill Sensivity Index is a GIS compiled from existing GIS data from several agencies and data verification from satellite images (LANDSAT, SPOT, ERS, and IKONOS). The project was funded by SIDA - Swedish International Development Cooperation Agency. The database and map cover the coastal area which includes 10 km. into land and 20 km. into the sea, consisting of coastal and marine physical parameters, biological parameters, and ecosystems, such as beaches, sea grass, mangrove forest, coral reefs, recreation areas, marine culture. The maps were created in 1:100,000 and 1:50,000 scale.
