About the Conference

The Ocean Optics Conference attracts a diverse audience of active practitioners in this field, including oceanographers, marine ecologists, limnologists, optical engineers, marine resource managers, and policy professionals from around the world.

Conference presentations will include the science of optics across all aquatic environments, research, and applications, including (but not limited to) biogeochemistry, environmental management and applications, instruments, techniques and observational systems, remote sensing, phytoplankton ecology, radiative transfer and optical theory, global change, and benthic processes. Attendees will attend plenary presentations during the day and interact with colleagues during scientific poster session receptions held in the exhibit/poster hall in the early evening. In addition to invited and contributed oral and poster presentations, the conference will provide the opportunity for community-wide discussions.
