A cabled observatory system for integrated long term, high-frequency biological, chemical, physical measurement for understanding planktonic ecosystem

Coastal ocean environment exhibits rapid change in time and space. Continuous long term measurements of environmental data are scarce. Environmental parameters, such as temperature and salinity, change due to multi-scale physical processes, such as Kuroshio and internal waves. A different scale of physical process affects planktonic ecosystem differently. In order to investigate how planktonic ecosystem responds to multi-scale physical processes, we have deployed a cabled observatory system (Oshima Coastal Environmental data Acquisition Network System, OCEANS) in coastal area of Habu port (Oshima island, Tokyo). OCEANS is a part of Joint Environmental Data Integration System (JEDI System) that is a research program supported by CREST (JST).
