Octopus - Ocean data portal

The Ocean Tool for Public Understanding & Science (OcToPUS) dynamically harvests and harmonises open-access marine data to provide a holistic and dynamic view of the changing state of the ocean, its biodiversity and human impacts.

OcToPUS aims to support scientific study, monitoring, policy and decision-making for the sustainable management of the ocean.

“OcToPUS enables scientists, policy makers and the general public to have open-access to a wide variety of current and high quality marine data to inform and catalyse marine research and ocean governance”.
Professor Alex Rogers, Octopus Founder; Chief Scientist, REV Ocean

Data & Technology

OcToPUS relies on established free and open-source geo-spatial technology to provide interactive access to dynamically updated, multi-dimensional data on the marine environment. A retrospective approach to big data achieves allows us to present information on temporal trends and variability of ocean phenomena to identify change in the ocean.

  • Ecosystem services: net primary production, natural hazard mitigation.
  • Oceanography: bathymetry, water (temperature, salinity, phosphate, oxygen, nitrate, silicate), currents, turbidity.
  • Ocean biodiversity: species distribution and occurrence, habitat suitability, deep-sea and coastal ecosystems
  • Human impact: ship traffic density, coral bleaching, ocean acidi cation, shing activity, marine mining licenses.
  • Administration: Exclusive Economic Zones, Marine Protected Areas, Regional Fisheries Bodies, Marine Ecoregions.

Open Access Data: OcToPUS harvests data from a large variety of open sources. Keeping data origin transparent and acknowledging providers is critical component of the platform. Details of sources and contributing institutions are detailed on the OcToPUS website. Further details can be found in the Ocean Data Explorer and are embedded in the file headers.

Ocean Data Explorer

The Ocean Data Explorer (above) is the central gateway to access, analyse and visualise ocean data in OcToPUS. An interactive web-mapping interface allows users to combine and query the layers in space and time. A scientific toolbox grants access to explorative data analysis and algorithms.

OcToPUShas been built and developed as a collaboration between the Oxford Martin School and the University of Oxford. Nekton and Oxford University are partnering on the development and management of OcToPUS.

We work with scientists, marine research institutes, Governments, conservation organisations and ocean managers to develop specific applications to support research, analysis, policy, monitoring, management and decision making.
