Ocean Data Bank

Marine Chemistry Database

        The Marine Chemistry Database represents one of the datasets in the Ocean Data Bank (ODB), which is operated by the Institute of Oceanography, National Taiwan University (IONTU). Since its foundation in 2015, it provides an archive of marine chemical data collected from marine research vessels of Taiwan and various data sources (see Our Data). The archive holds not only records of CTD and surface seawater pCO2 but also bottle sampling data of more than 10 different measured variables (incl. DO, chlorophyll, and nutrients).
 
        The release of any data in this database is subject to policies and regulations of the National Science and Technology Council (NSTC). Therefore, completing and sending an application form to yehtc@ntu.edu.tw is mandatory for data requests.

Our Data

The data held in the Marine Chemistry Database are divided into 3 areas:

CTD

CTD data were collected from marine research vessels of Taiwan. Our inventory not only provides access to continuous profiles of temperature and salinity but also dissolved oxygen, transmission, and fluorescence data collected with auxiliary sensors.

Bottle

Bottle data were mostly contributed from National Science and Technology Council projects. In addition, there are also South East Asia Time-series Stations (SEATS) data from Dr. Fuh-Kwo Shiah (Research Center for Environmental Changes, Academia Sinica) and the bottle data from the lab of Dr. Chen-Tung Arthur Chen (Department of Oceanography, National Sun Yat-sen University) and distinguished Professor Su-Cheng Pai (Institute of Oceanography , National Taiwan University ).

pCO2

Underway pCO2 data are provided by the New Ocean Researcher 3 (NOR3) Marine Instrument Center. Following internal data quality control, the data are transmitted to and stored in the Marine Chemistry Database.

Our Services

Data access

Data in ODB falls under the data release policies of the National Science and Technology Council, Taiwan. Therefore, sending the request form to yehtc@ntu.edu.tw is required to release any data.

Data Display

Please visit the ODB Marine Chemistry Viewer website which facilitates data visualization of the chemistry data stored in the ODB by querying temporal and spatial ranges.

Station metadata

Please visit the CTD stations and the Bottle stations webpages for retrieving the metadata of individual stations or vessels. Metadata includes station coordinates, maximum depth, and availability of measured variables.
