In our country surrounded by the sea with diverse environment, our life is getting a lot of benefit from it. However, global changes have been suggested to affect marine environments and to dwindle the marine biological resources. Under these circumstances, accumulating data is needed for understanding the current status of marine environment and marine biodiversity, in which has been obtained during a wide range and number of research and observational activities, as knowledgebase on the marine and the earth sciences around Japan.
JAMSTEC has been opened such data by the data sites or the database systems according to these data types, observational platforms or research projects. One of main mission of our group is to construct and maintain several information systems (e.g. DARWIN+, JAMSTEC Data catalog, JAMSTEC Documents Catalog) for the aims to contribute to open data / open science. And also to continually improve technical means for those systems in order to make it easy, integrative and convenient to use the data, information, knowledge, products and services necessary for deepening scientific understanding and sound decision making.

The other main mission of our group is to construct and maintain a image database system "J-EDI". This system provides with the numerous data of deep-sea videos and photos to the public with detailed information of these contents, which has been obtained with observations using several manned and unmanned deep-sea research submersibles (e.g. DSRV "SHINKAI6500", ROV "HYPER-DOLPHIN"). And also, is to construct and maintain an integrated data system "BISMaL", to distribute the collected and integrated information of marine life for understanding of marine biodiversity and marine environmental changes.
In addition, our group has been construct the global environmental information infrastructure with data integration function for the aims to contribute to marine and earth science research, to contribute to the social and economic fields such as regional fishery industry, and to contribute to "open data / open science" by deploying sustainable services to realize a sustainable society.
Our group has been construct the data system in cooperation with several research section in JAMSTEC such as the Ocean Radar data site "MORSETS" that is provided quasi-real-time surface current maps of the Eastern Tsugaru Strait, which has been obtained with the HF radar data station, and is provided archived data. And also the data download site "JAGDAS" has been provided grid datasets including ocean state estimation data, generated in JAMSTEC.

Trough the construction and operation of such systems, we are contributing to cooperation with international data centers and providing data obtained by JAMSTEC.
Although, "BISMaL" is a data system of JAMSTEC, it also functions as the system of the Japan Ocean Biogeographic Information System Center (J-OBIS), the Japan node of the Ocean Biogeographic Information System (OBIS) in which is operated by International Oceanographic Data and Information Exchange (IODE) under the umbrella of the IOC/UNESCO. Data and information collected and integrated by J-OBIS are opened to the public and provided to OBIS through "BISMaL". "BISMaL" is contributing to global data sharing and information exchange as well as working as a data system of JAMSTEC. And also, "JAMSTEC Data catalog" is sharing contents with international data centers such as the NASA's Global Change Master Directory (GCMD) and "GEOSS Portal".
We will be able to contribute to provide information complementing statistical analysis necessary to solving problems in various social benefit areas, by strengthening international cooperation, and to play an important role to support the activity of social benefit areas such as the realization of the United Nations' the 17 Sustainable Development Goals (SDGs) etc.
