3. Topic in FY2016

(1) Opened totally renewed E-library of Deep-sea Images (J-EDI)

The JAMSTEC E-library of Deep-sea Images (J-EDI) was fully renewed in FY2015 in order to improve the accessibility of users to video/photo data and enable to visualize observation data during dives. In FY2016 after transfer and re-registration of data we opened the new version of J-EDI. We also enabled users to download still images with original resolution. With this renewal visibility and operability of the system were improved and original resolution images were available online, so monthly average of download of videos and photos increased by a factor of 2 and 3.2 respectively. We also started adding new “Staff’s Favorite Deep-sea Videos” monthly and delivering information of the video of the month via Twitter and Facebook. With these improvements visitors to J-EDI were greatly increased and J-EDI became more familiar. According to the evaluation of the access record analysis we prepared for the access by mobile devices and updated the login service in order to increase the number of users.

(2) OBIS Steering Group Meeting was held at GODAC

JAMSTEC provides the OBIS (Ocean Biogeographic Information System, an international marine biological database) with biological occurrence data through BISMaL, and also operates the OBIS Japanese node (J-OBIS) using BISMaL as a core information system. The 6th session of the IODE Steering Group for OBIS (SG-OBIS-VI) was held at GODAC (Nago city, Okinawa, Japan) during 1 to 3 February 2017 with participants of 35 members from 17 countries. JAMSTEC supported the meeting as a local host, and promoted collaborations among Asian local nodes by providing the opportunity to meet together.
