Marine life is controlled by the very variable conditions in the oceans; some species have certain temperature and salinity requirements, others species need plankton to feed at. OCEBIS (OCEan Biological Information Service) is a web service that aims at providing maps of potential biological drivers that provides the basis for life in the oceans and identifying potential living areas for marine species. Examples are maps of frontal zones and marine spatial connectivity maps. To deliver these maps OCEBIS uses real-time hydrography from the Copernicus Marine Service. The OCEBIS portal is based on Geoserver so that data is displayed on pretty geographical maps; the portal has drop-down menus displaying the available products generated by OCEBIS, as well as static background layers. The portal allows zooming into areas of interest and overlying different maps, and offers a basic toolbox for data exploration. The service currently applies to the European North West Shelf.
All data produced by OCEBIS as well as the displayed graphics, are freely available to the public. No registration is necessary. Data is provided as is and without any warranty whatsoever. Currently the following biological data layers below are updated dynamically. Hourly update frequency means Copernicus Marine Service is polled at hourly basis for new raw physical/biogeochemical data sets
|bloom index||d/dt(vertically integrated primary production)||hourly|
|Depth of pycnocline||water density by UNESCO interpolation||hourly|
|Max density gradient||water density by UNESCO interpolation||hourly|
|Surface estaurine front||characterized by 32 PSU < salinity < 33.5 PSU||hourly|
|Logarithm of light at seabed||minus vertical integral of attenuation coefficient||hourly|
|Depth of vertical maximum of phytoplankton concentration||-||hourly|
|Vertical maximum of phytoplankton concentration||-||hourly|
|Sea bed potential temperature||directly from Copernicus Marine Service||hourly|
|Mixed layer depth||directly from Copernicus Marine Service||hourly|
|Sea surface temperature||-||hourly|
|Surface-bottom temperature stratification||-||hourly|
|Thermal mixing front||evaluated as magnitude of gradient of surface-bottom stratification||hourly|
|Depth of max temperature gradient||-||hourly|
|Max temperature vertical gradient||-||hourly|
|Surface vorticity||curl of surface current vector field||hourly|
|Hydrodynamic transport of passive tracers by starting position||User selects starting time and position and transport period. This can be used to assess hydrodynamic transport of early life stages, when spawning locations are known||transport kernels computed updated on seasonal basis|
New data layers may be added upon user interest and requests
How the service is operational
OCEBIS is a downstream service based on Copernicus Marine Environment Monitoring Service (CMEMS). This means that ocebis.org on an hourly basis retrieves new data from Copernicus Marine Environment Monitoring Service and generates maps of potential biological drivers which are made available on ocebis.org. In this way, OCEBIS gives a real-time view of the ocean state from a biological point of view. Some data types like spatial connectivity maps are generated on seasonal basis. Due to storage limitations OCEBIS only provides a limited backlog of data. However, the user may download back-end software used at ocebis.org and generate any time series downloading data from Copernicus Marine Environment Monitoring Service data archives.
Usage of data and displayed graphics from OCEBIS should be acknowledged by adding "... generated with / using data from OCEBIS(ocebis.org). Data from ocebis.org was generated using E.U. Copernicus Marine Service Information” at a suitable places in the context making usage of OCEBIS data.
