Last Update : 02 Mar., 2010

Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has performed wide range of marine-earth observations, for example oceanographic observations via research vessels and submersibles, moored observations and terrestrial observations. Data and sample information from these oceanographic or terrestrial observations are publicized through relevant data sites or databases on the Internet.
"JAMSTEC Data Search Portal" is an entrance to such oceanographic/terrestrial observation data and sample information in JAMSTEC. Users are able to search JAMSTEC’s research activities or data/samples across those data sites or databases by area, period or variables. This portal provides links to the data publication pages from search results.

By selecting data type(s), refreshing a map and choosing area with "Quick Search" tool users will get the list of records covered by the search area. Links to data publication sites will appear on the search result and users are able to go to the relevant pages. Search by period or variable is also available.

2.1 Map Window

On this window users can select data type, zoom up/down and pan the map, and designate search area.

• Main Map
On the base map of topography, coast lines and borders, data acquisition positions are shown as points or lines. Colors or symbols differ according to data types. More information, for example names of ocean bottom features, cruise numbers, dive numbers or observation site names, may be displayed if zoomed up.


• Data Selection
First please select data type(s) to be retrieved. All data are selected in the initial state. It is available to select more than one data type. After changing selections "Refresh" must be applied. Users can select all data types by "All" and can select no data type by "Clear".


• Legends
Legends or symbols are shown.


• Global Map
The extent of the main map is displayed in a red rectangular.


• Map Tools
Click icons of map tools and click/drug on the main map. Tools are "Zoom In/Out", "Pan", "Global View", "Previous View" and "Initialize". "Zoom In" is default.


• Search Tools
Click the "Quick Search" icon and drug on the main map to designate the search area. Retrieved data are highlighted in yellow and "Search Result Window(s)" will be popped up. "Clear Selection" tool can erase highlight color. "Advanced Search" button opens the retrieval condition window for complex search.


• Map Information
Extent of the main map and latitude/longitude of the mouse cursor are displayed.

2.2 Retrieval Condition Window

• Select Data type
Data types selected in the main map are already set. To change data types click “From Main Window” and go to the Map Window.


• Select Research Vessel
Select "R/V name" to search by name(s) of research vessel and/or select "Cruise ID" to search by cruise name. Users can select ship name(s) from the list and input cruise name in the text box.


• Select Submergible
Select "DSRV name" to search by name(s) of submersible and/or select "Dive Number" to search by dive number. Users can select submersible name(s) from the list and input dive number in the text box.


• Select Variable
To search by observation terms select variable(s) from the list.


• Search Period
Input "Start Date" or "End Date" from the calendar or input date in yyyy-mm-dd format to search by period. To specify one single day input the same date into both. To specify an unlimited period in one direction leave the relevant box null.


• Search Area
Extent of main map is already set as retrieval area. To change the area, hit "From Map Window" and go to the Map Window.

2.3 Search Result Window

Data hit by the retrieval conditions are shown in the list. Selected more than one data type, plural "Search Result Windows" will appear.
Because some of the properties are written in Japanese, users using other language may see garbled characters for such properties.

• Number
Click the number and the relevant data is highlighted in red on the main map.


• Jump Button
Jump button will appear in the "Web Site" column, if relevant data publication page is available.


• Total Data
Total number of the retrieved data is shown.


• More Records
Up to thirty records are shown in "Search Result Window". If more than thirty records are hit, "More Records", link to the next page, is shown in the bottom of the window. In the next page "Previous 30 Records" , link to the previous page, is shown.

Following data/samples or research activities are available now on this system. Data on this site will be updated or added without notice.
