African Register of Marine Species

The contribution of the African institutions to the Ocean Biogeographic Information System (OBIS) and the World Register of Marine Species (WoRMS) was improved considerably through the organization of focused workshops during which experts from ODINAFRICA institutions in Africa developed databases on marine molluscs, sponges, and decapods.

Coastal and Marine Atlases

The African Coastal and Marine Atlas (www.africanmarineatlas.net) was initiated as a continental-scale online resource of public-domain geospatial data. The project was designed to identify, collect and organize data sets into an atlas of biophysical themes, including: basemaps, geosphere, hydrosphere, atmosphere, biosphere and the human and built environment.

Sea Level Data Collection

The African network for measurements and monitoring of sea level was expanded and upgraded by installing new tide gauges in Cameroon, Congo, Djibouti, Egypt, Ghana, and Mauritania. The installation of Global Navigations Satellite Systems – GNSS receivers at the sea level stations in Takoradi (Ghana), and Inhambane and Pemba (Mozambique) provides the connection between the horizontal and the vertical datum at these locations.

The tidal and GNSS observations together allows one to monitor crustal motions at the tide gauge locations in order to derive absolute or climate related signals in mean sea level from the tide records. Experts from the African countries used the training provided to analyse data from the sea level stations around Africa and prepare tidal predictions.

Information on the network (equipment types and location, reports, trainings etc) is available on the African Sea Level Network website (www.sealevel.odinafrica.org/), while the data from the stations can be accessed near-real time at www.sealevelstations.net. Thanks to the combined efforts of GLOSS, IOC/tsunami and ODINAFRICA, Africa now has a network of 40 sea level stations.

Ocean Data Collections and Catalogues

National data collections were developed. These consisted of ocean station data (from global and local sources), satellite analyses, ocean climatologies, weather climatologies, geology, base mapping, ecology, fisheries. The institutions participating in ODINAFRICA have been provided with a data CD containing data from the IOCEA and IOCWIO regions obtained from other IODE data centres around the world. In addition a programme to identify, digitise and repatriate other datasets which are available in foreign institutions to the regions was implemented in the framework of GODAR. Several ODINAFRICA NODCs published their National Marine Database collections on CD-ROMs and other media. A catalogue of data sets can also be accessed through a central GeoNetwork server located at: www.geonetwork.iode.org/geonetworkAMA
