The OceanObs' 19 will be held on September 16-20, 2019 at Honolulu, Hawaii, USA. OceanObs’19 seeks to improve response to scientific and societal needs of a fit-for-purpose integrated ocean observing system, for better understanding the environment of the Earth, monitoring climate, and informing adaptation strategies as well as the sustainable use of ocean resources.

With the efforts of all panels and research foci, CLIVAR submitted 10 white papers to contribute to the conference as well as the ocean observing system.
