Third Annual Kick-Off Meeting (2015)
Apr 13, 2015
On April 13, 2015, the JEDI-System team held the third annual kick-off meeting at Tokyo University of Marine Science and Technology. At the annual kick-off meetings, the JEDI-System members discuss recent developments, research and the next steps.
JST, CREST International Workshop
Oct 21, 2014
In late October, the JEDI-System Project, headed by Professor Hidekatsu Yamazaki, joined with Dr. S. Lan Smith, the principal investigator in a JST, CREST project at JAMSTEC, in order to host an workshop titled 'Advances in the Plankton Ecosystem Model and the Evaluation of Biodiversity'. The other conveners included Professor Simon Levin (Princeton University), Professor Ken Denman (University of Victoria), and Professor Chih-hao Hsieh (National Taiwan University). The workshop was held at Tokyo University of Marine Science and Technology's Rakusui Hall.
OCEANS Underwater Observatory Deployment
Featured Article
Aug. 12, 2014
OCEANS is an underwater observatory system that enables real-time viewing of what is happening in the ocean around Oshima Island, Japan (Fig. 1). By taking advantage of the live data, we can discover what kinds of fish swim through the area or what kinds of plankton live in a parcel of seawater. For example, our research team found that highly dense mysida aggregations appear (Fig. 2), indicating a biologically rich environment around Oshima Island.
2014 JST, CREST Site Visit @ Oshima
May 30, 2014
In early May 2014, Professor Koike, the research supervisor from JST, CREST, visited Izu-Oshima Island to inspect the OCEANS site (Oshima Coastal Environmental data Acquisition Network System). The main topic of discussion was how to deploy the cable and the node. The OCEANS node contains various sensors, such as temperature sensors, a camera, and a hydrophone. The temperature sensors will be strung on a cable (called a 't-string') attached to the node.
Mandal Paper Published in PLOS ONE
May 2, 2014
The highly respected open-source scientific journal PLOS ONE has published a JEDI-System paper by Sandip Mandal, Christopher Locke, Mamoru Tanaka, and Hidekatsu Yamazaki entitled 'Observations and Models of Highly Intermittent Phytoplankton Distributions.' The paper, accepted March 20, 2014, applies a new planktonic ecosystem modeling method called the closure approach and was written as part of the JEDI-System subprogram S2. New Planktonic Ecosystem/NPZ Model.
