About us

Founded by Taiwan’s National Science Council (NSC, renamed on 2014/3/3 to the Ministry of Science and Technology, MOST) in 1987, the Ocean Data Bank (ODB) is being operated by the Institute of Oceanography, National Taiwan University (IONTU). This is an interdisciplinary oceanic information system based on a Service Oriented Architecture (SOA) for the Western Pacific Ocean. The database has compiled various oceanic data acquired in the surrounding seas of Taiwan since 1986. The service let users search multidisciplinary datasets via web browsers. This database also integrated with a Geographic Information System (GIS), and generates instant graphs and maps (with 15′ grid resolution and monthly timescale) on physical, geophysical, or biological oceanographic information.

Marine Geophysics database

The oceanographic database is under the Ocean Data Bank (ODB), which mainly archive and disseminate the ocean researcher I、II、III data. Currently, there are mainly two different types of data available in the ODB for Ocean physics: Shipboard Acoustic Doppler Current Profiler (Sb-ADCP) data and Conductivity-Temperature-Depth (CTD) data.

Marine Geophysics database

Marine Geophysics database maintains a large volume of bathymetry, seismic navigation data, Sub-Bottom Profiler data and other data types.Data sources include ocean researcher I、II、III, and collected during marine cruises from 1990 to the present. Our data sets of these digital databases have been released as a DVD-ROM or VCD-ROM sets , and the Geographic Informatio system (GIS) have been provided with ArcIMS .Currently only a limited number of lines are available online. Digital seismic reflection data (SEGY files) and Sub-Bottom Profiler data are available on request and can be searched for using WebGIS by geographic area, survey, cruise, or geophysical parameter.

Bathymetric Data around Taiwan

Digital bathymetric data set has been produced by compiling available shipboard bathymetric data supplemented by global bathymetric data sets. It may serve the basis for studying interrelationship among marine geology, physics, chemistry, and biology. We provide two data sets as follows:

500-m gridded data set : Coverage is 18° N to 27° N, and 117° E to 125° E.

1000-m gridded data set : Coverage is 2° N to 35° N, and 105° E to 135° E

Bio-ocean database

We started to build up a bio-ocean database in late 2009. It is focusing on the zooplankton abundance in the surrounding seas of Taiwan, providing the essential biological parameter to test regional ecological hypotheses. This bio-database is also part of our interdisciplinary ocean integrated database followed with the main structure of World Ocean Database 2009, the world largest ocean database running by National Oceanic and Atmospheric Administration, U.S.A. Users can not only build up a query easily according to their target geographical regions, sampling methods, research ship cruises, stations as well as a particular taxonomic groups or species, but also can cross search the correlated environmental data such as the Conductivity, Temperature, Depth (CTD) records. Our bio-database has been collected over 6000 plankton abundance records over the past six months from historical references. Data after the quality check will be released in the system which is planned launching in fall, 2010.

Marine Information Management System

Marine Information Management System is a Web-based, n-tier, service-oriented architecture composed of web clients, application server(s), database(s) and file server(s) and is based entirely on standard Internet protocols including HTTP / HTTPS, XML and SOAP [Simple Object Access Protocol]. It is different from transitional isolated systems. This framework is used in an application project, it solves user information integrate between marine physical system ,marine geophysical system and bio-database systems, shows its advantage in solving related problems. This model is applied to improve the interoperability of heterogeneous systems.
